Annual Hydrologic Data Report, Volume III – Weather – 2801 W Durango St., Phoenix, AZ 85009 (602) 506-1501 Page 3 Introduction This publication is part of a three-volume report containing hydrologic and meteorological data collected by the Flood Control District of Maricopa County during Water Year 2024. This report is Volume III and contains weather station statistics. On-line users of this document have additional resources available by selecting hyperlinks. Weather Station names will link to the FCDMC web page for that weather station. Other hyperlinks will link within the document. All weather stations report temperature and relative humidity; many also report a combination of wind direction, wind speed, barometric pressure, and solar radiation. In addition, dewpoint temperature is calculated every 15 minutes at all weather stations using the temperature and relative humidity data. The temperature, relative humidity, and wind sensors transmit data every 15 minutes; the barometric pressure and solar radiation sensors every 30 minutes. The following paragraphs describe the arrangement, collection, and compilation of the monthly weather station data contained in this report: • Weather station data presented in the monthly weather summaries are based on the “2024 Water Year” which began on Oct. 1st, 2023, and ended Sept. 30th, 2024. Each monthly summary represents one weather station and lists daily weather station statistics by sensor. The monthly summaries are arranged chronologically and by station name. • An index of ALERT System weather stations, code names, locations, and installation dates are located on page viii. This is followed by a sensor id number matrix listing the available sensors at each weather station. Both indexes are sorted by station name in alphabetical order. Station names are hyper-linked to additional weather station information and climate summaries (where available). • The monthly weather summaries contain daily maximum, minimum, and mean values for temperature and dewpoint. The monthly summaries also contain daily maximum and minimum values for relative humidity and barometric pressure. Finally, the monthly summaries contain daily maximum peak wind and solar radiation values. All of the ALERT system weather stations record precipitation; however, that data is located in the FCDMC Hydrologic Data Report Volume I. • The unit of measurement for daily maximum, minimum, and mean temperature data is in degrees Fahrenheit (˚F). The daily maximum, minimum, and mean dewpoint data are also in degrees Fahrenheit (˚F). The daily maximum and minimum relative humidity data are in percent (%). The daily maximum peak wind data are in miles per hour (mph). The daily maximum and minimum barometric pressure are in millibars (mb). The daily maximum solar radiation data are in watts per square meter (w/m2). • All data presented in the weather summaries are rounded to the nearest whole value. Additional and/or more detailed sensor data in hard copy or electronic copy are available for the weather station sensors listed in this report.

The summer heat held its ground well into October 2023, which was statistically much warmer and drier than average. El Niño conditions prevailed through winter 2023, which are generally associated with statistically wetter/cooler winters in Arizona. This panned out for most of Southern AZ, and much of Maricopa County experienced at or above average precipitation from Dec-Feb. This wetter pattern persisted through the spring as well, with a majority of the county seeing above normal precipitation from Mar-May. Scientific studies have shown an abnormally wet and cool winter/spring has been linked to a resultant delayed and drier monsoon circulation. Monsoon 2024 did end with another historic lack of rainfall at observation locations in Arizona, especially within Maricopa County. For example, Phoenix Sky Harbor received 0.74” of precipitation between June 15th and September 30th. This tied for the 7th driest monsoon season dating back to 1896. Monsoon 2024 for the ALERT network was the 3rd driest monsoon since 1981, only surpassing Monsoon 2023 by a small margin. Another stand-out during this time was the heat, which quickly cemented itself across the region in early May and continued through early September. More detailed weather and rainfall information on this past monsoon can be found here. Table 6 below shows temperature data averaged across the entire ALERT weather station network. Values were calculated using WY2024 data. Anomalies and ranks were calculated using data between 2000 and 2024. Overall, the mean temperature across all stations for WY2024 was 72.9˚F, which was 1.2˚F warmer than the long-term network average of 71.7˚F and ranks as the 4th warmest WY on record (since 2000). Looking at the anomaly data (not shown), 33 of the weather stations had a warm bias between +0.3˚F and +3.6˚F above their respective long-term averages. The Gila Bend Landfill station observed their warmest mean WY temperature on record (78.2°F). There were 6 stations cooler than their long-term average (-0.2°F to -1.8°F anomaly) that were located either in the foothills of northern Maricopa County or mountains of southern Yavapai County. Note the Gila Bend Mountains station was not included in 2024 mean and anomaly temperature evaluation due to limited observations (only 65 percent of possible WY2024 observation days recorded). Table 6: ALERT Network Temperature Statistics for Water Year 2024 Statistic Avg Temp (˚F) Avg Max Temp (˚F) Avg Min Temp (˚F) Value Anomaly 72.9 +1.2 84.1 +0.4 61.6 +1.7 Rank 4th Warmest (2000-2024) 11th Warmest (2000-2024) 4th Warmest (2000-2024) The average maximum temperature across all stations for WY2024 was 84.1˚F, which was 0.4˚F warmer than the long-term average of 83.7˚F. This ranked as the 11th warmest WY on record since WY2000. There were 27 weather stations warmer than their respective long-term mean maximum temperatures (+0.2°F to +2.6°F anomaly) with 10 below (-0.1°F to -3.6°F anomaly). There was one station that set new warm WY average maximum temperatures (Mobile). No new daily maximum temperatures were set during WY2024, but the McMicken Dam weather station tied its historical Annual Hydrologic Data Report, Volume III – Weather – 2801 W Durango St., Phoenix, AZ 85009 (602) 506-1501 Page 17 daily maximum temperature (116°F). The G&F Woolsey Peak weather station observed daily maximum temperature for WY2024 tied for coolest on record (100°F). The average minimum temperature across all stations was 61.6˚F, which was 1.7˚F warmer than the long-term average of 59.9˚F. Water Year 2024 ranked 4th warmest on record since WY2000. Most stations (33) were warmer (+0.1°F to +3.7°F anomaly); however, 4 relatively higher elevation stations located in northern Maricopa County (Aguila VFD, Desert Mountain School, Rackensack Canyon, and Sycamore Creek Upper) had an average minimum temperature below their respective long-term means (-0.1°F to -1.5°F anomaly). There were 3 stations that set new warm WY average minimum temperatures (Buckeye FRS #1, Camelback @ Loop 303, and Jefferson Park). No new daily minimum temperature records were set during WY2024; however, the Sycamore Creek Upper weather station tied its historical coolest daily minimum temperature on record (19°F), while the observed daily minimum temperature for WY2024 at G&F Woolsey Peak and Thompson Peak tied for warmest on record (47°F and 34°F, respectively). Annual Hydrologic Data Report, Volume III – Weather – 2801 W Durango St., Phoenix, AZ 85009 (602) 506-1501 Page 18 Brief Review of Excessive Summer Heat for Water Year 2024 This Water Year undoubtedly included one of the hottest summers on record. The definition of ‘hottest’ is subjective, but data can give insight into the extremity of high values, length of heatwaves, or overall presence of heat. Until recently, summer 2020 could be defended as the hottest summer on record at Phoenix Sky Harbor and across the ALERT network. According to the National Weather Service Phoenix WFO, the Sky Harbor Airport weather station saw 19 daily high temperature records tied/broken. A more detailed summary on summer heat in 2020 within the ALERT network can be found here. The summer heat of 2023 overall was also record-breaking; however, it varied greatly month-to-month. For instance, the start of the summer season was unusually cool at Phoenix Sky Harbor with a June mean temperature departure of 1.9°F below normal. Record heat quickly ramped up into July 2023 as Sky Harbor recorded 31 consecutive days of high temperatures over 110˚F, which at the time broke the previous streak of 18 days set in 1974. Summer 2024 displayed a steady, long-lasting heat, including a new record 113 day streak of high temperatures over 100˚F at Phoenix Sky Harbor. Very hot temperatures also continued into the early fall season as highlighted by an all-time new September record temperature of 117°F being set on the 28th. The data and following discussion will present a deep dive into the summer heat for each of these respective years and provide insight on the ‘hottest’ summer for the ALERT network. Because of the persistent heat and the meteorological significance of September 2024, the review includes heat data through an extended summertime period (June-September). There was a total of 40 ALERT weather stations chosen to take part in this summary. These stations represent various regions across Maricopa County, including the greater Phoenix Metropolitan area and lower rural deserts, along with some portions of Pinal and Yavapai counties. Elevations for these stations range from 735 ft. to 7,975 ft. Each station provides at least 8 years of weather readings, and 34 stations have 15 or more years of observational data. Table 7, on the next page, compares temperature data for the defined summer period (JJAS). The left side of the table includes weather station information including elevation, years of station inventory since 2000, and the temperature sensor ID number. The right side of the table includes the 2024 mean temperature, the normal mean temperature (2000-2024), the temperature difference from the longterm mean (anomaly) over the 4-month span, standard deviations, and standardized anomalies (SA). Values displayed in red for the 2024 Mean Temp. column indicate either a matched (light red) or record (bold red) hottest average summer temperature for the respective station. Out of the 40 stations in the ALERT network, 39 (98%) experienced above average mean temperatures and 26 (65%) experienced the record hottest mean temperature throughout the summer. The spatial distribution of this record heat spanned across the rural deserts, urban centers within the lower Phoenix Valley, and reached far north to the stations in the higher elevations. The only stations that did not surpass this threshold were G&F Woolsey Peak and Magma FRS.

Next, standard deviations were calculated to observe the variability of the temperature datasets at each weather station over the 2000-2024 period. The greater the standard deviation, the less historically meaningful the 2024 anomalies were. Finally, standardized anomalies were calculated using the anomaly and standard deviation data at each station. Standardized anomalies are used with weather data to find statistical outliers (uncommon events) in datasets after removing bias. Absolute values between zero and one meant the anomaly fell within one standard deviation of normal and, therefore, not considered to be an unusual event. Values greater than one were outliers and, in this case, the greater the value, the more uncommon the event was. Looking at temperature anomalies, 28 stations experienced a 2.0˚F or greater warm anomaly while 11 met or exceeded 3.5˚F during the period. The average anomaly for all stations (not shown) was 2.6˚F. Of the 40 station’s standardized anomalies (SAs), 29 (73%) were greater than 1.0 and 16 (40%) met or exceeded 2.0. The average temperature SA across all the weather stations was 1.6 (not shown), which exceeded the average temperature SA of 1.2 in 2020. To put some of those numbers into perspective, values that fall between 0 and ±1 indicate the anomaly fell within one standard deviation of normal and is considered a common event as it has a 68% probability of occurrence. Values of ±2 have a 27% probability of occurring and ±3 comes with a probability of just 4%. Table 8, below and continued on the next page, compares additional temperature datasets at each of the ALERT weather stations. The left side of the table depicts weather station information including elevation. The right side of the table includes monthly mean temperatures for June, July, August, and September. The values highlighted in red represent matched records for the month. The values in bold red represent new records at the station for the month. The final three columns show the total number of days where high temperatures exceeded 100˚F and 110˚F and minimum temperatures exceeded 90˚F. TABLE 8: Additional 2024 Temperature Data Elev.

Of all weather stations, 12 (30%) new records were matched or set during June. Additionally, 36 (90%) stations recorded above normal mean values. Moving on to July, 8 (20%) stations matched or set their warmest July on record, and all 40 weather stations experienced above average values. August 2024 took a step back from breaking records and only one station matched a previous mean temperature record. However, 37 (93%) stations experienced above average temperatures. September saw 22 (55%) stations match or break record mean temperatures, with 39 (98%) experiencing above average temperatures. Table 9, next page, displays a side-by-side comparison between the years of interest. On the left side of the table is the ALERT Weather Station name, elevation, and long-term normal mean summer temperature (JJAS, 2000-2024). The next columns include the mean temperature and Annual Hydrologic Data Report, Volume III – Weather – 2801 W Durango St., Phoenix, AZ 85009 (602) 506-1501 Page 22 anomaly for 2020, followed by those same two variables for 2023 and 2024. Values displayed in red represent a tied summer heat record within that year, and values displayed in bold red represent a broken summer heat record. The blue highlights represent the same characteristics (lighter for a tied record, darker for a broken record), but only considering the values for the years prior, not following. For example, at Usery Mtn. Park, the record mean temperature was broken in 2020 with a value of 93˚F. This value is highlighted in dark blue because it was the record at the time but is not shown in red because the record was broken in 2024 with a value of 94˚F.

Most notably, of the 24 records that were set in 2020, only 5 total stations maintained their records, while the other 19 were tied or broken. Of those values, 17 were tied/broken in 2024. Looking at anomalies, as mentioned before, the average temperature anomaly across all stations in 2024 was 2.6˚F. To compare, the average anomaly (not shown) for 2023 was 0.6˚F in 2023 and 2.0˚F in 2020. To summarize, 2020 and 2024 were both anomalously hot years for the ALERT network, with 2024 surpassing the 2020 mean anomaly by 0.6˚F. Additionally, the 2024 summer period saw more heat records broken or tied than in 2020 across many lower desert elevation sites. The temperature data presented help show that historic summer heat impacted the ALERT network in 2020, 2023, and 2024; however, the recent 2024 summer was overall the hottest on record.
