...A WARM AND VERY DRY SUMMER...
SUMMER 2025 BEGAN WITH AN EARLY SEASON HEATWAVE IN MID TO LATE JUNE
WITH SEVERAL DAYS IN THE LOW TO MID 90S. JULY 2025 COULDN`T HAVE
BEEN MORE DIFFERENT THAN LAST YEAR...UNLIKE WHEN THERE THERE 0 DAYS
ABOVE 90 DEGREES IN JULY 2024, HOT AND VERY HUMID CONDITIONS
PERSISTED THROUGH JULY. THIS YEAR, JULY WAS THE 2ND MOST HUMID JULY
SINCE DEWPOINT RECORDS BEGAN IN 1911. THE AVERAGE DEWPOINT WAS 67.53
DEGREES, MAKING IT THE MOST HUMID JULY SINCE 1933 WHEN THE AVERAGE
DEWPOINT WAS 67.97 DEGREES. THE PEAK OF THE SUMMER HEAT OCCURRED IN
MID TO LATE JULY; THE HOTTEST DAY OF THE SUMMER WAS ON JULY 24TH
WITH A HIGH OF 95 DEGREES. AUGUST BROUGHT SOME MUCH NEEDED RELIEF
FROM THE HEAT AND HUMDITY, ESPECIALLY TOWARDS THE END OF THE MONTH.
THERE WERE 23 90+ DEGREE DAYS THIS SUMMER, WITH 8 IN JUNE, 9 IN
JULY, AND 6 IN AUGUST. OVERALL, SUMMER 2025 HAD AN AVERAGE
TEMPERATURE OF 73.5 DEGREES, WHICH IS 1.5 DEGREES ABOVE NORMAL AND
RANKS AS THE 20TH WARMEST SUMMER ON RECORD. THIS WAS THE WARMEST
SUMMER SINCE 2018.
THE SUMMER MONTHS WERE NOTABLY DRY AT TIMES AND LACKED WIDESPREAD
SOAKING RAINFALL. ANY APPRECIABLE RAINFALL THIS SUMMER WAS FOUND
MAINLY IN DAILY POP-UP SHOWERS AND STORMS, AND UNFORTUNATELY, MANY
OF THOSE STORMS MISSED THE FORT WAYNE AIRPORT. THERE WERE MANY DAYS
WERE NO RAIN WAS MEASURED AT THE AIRPORT BUT OTHER LOCATIONS NEARBY
DID RECIEVE RAIN. FOR THE SECOND SUMMER IN A ROW, THERE WERE NO DAYS
WITH A RAINFALL TOTAL OVER AN INCH; THE HIGHEST 1 DAY TOTAL WAS
0.91", WHICH OCCURRED ON JUNE 18TH. IN TOTAL, FORT WAYNE RECIEVED
7.56" OF RAIN THIS SUMMER. THIS IS MORE THAN LAST YEAR`S TOTAL OF
6.73", BUT STILL WAS 4.77" BELOW NORMAL AND RANKS AS THE 24TH DRIEST
SUMMER ON RECORD.
A MONTH BY MONTH SUMMARY IS BELOW:
...JUNE BRINGS THE FIRST SUMMER HEAT WAVE...
WHILE JUNE 1 WAS NOTABLY COOL (DAILY AVERAGE TEMPERATURE WAS 10
DEGREES BELOW NORMAL), THE REMINDER OF THE MONTH WAS WARMER THAN
NORMAL. ONLY SEVEN DAYS THIS MONTH SAW AN AVERAGE DAILY TEMPERATURE
BELOW NORMAL. DURING A LATE-MONTH HEAT WAVE, FORT WAYNE TIED A
RECORD WARM MINIMUM TEMPERATURE (JUNE 22, 74 DEGREES TIED WITH 1988)
AND RECORDED A HIGH TEMPERATURE OF 90 OR GREATER FOR SEVEN STRAIGHT
DAYS.
THE LONGEST STRETCH OF 90S ON RECORD IS 22 DAYS ENDING JULY 18, 2012.
JUNE OF LAST YEAR SAW A SEVEN-DAY STRETCH OF 90S END ON JUNE 22ND.
THE TOTAL NUMBER OF 90 DEGREE DAYS THIS MONTH IS EIGHT, WHICH
MATCHES JUNE 2024 AND IS ABOVE THE AVERAGE OF FOUR.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 73.2 DEGREES WHICH IS 2.5
DEGREES ABOVE NORMAL. THIS TIES 2018 AS THE 16TH WARMEST JUNE ON
RECORD. WHILE 90-DEGREE DAYS CERTAINLY NUDGED THE MONTH`S AVERAGE
TEMPERATURE ABOVE NORMAL, OVERNIGHT LOWS CARRIED NOTABLE WEIGHT. THE
MONTH`S AVERAGE LOW TEMPERATURE OF 63 DEGREES TIES 1952 AND 1943 AS
THE 8TH WARMEST ON RECORD. NOTE THAT JUNE 2021 RANKS AS THE 7TH
WARMEST AT 63.2 DEGREES.
AMID THE HOT AND STEAMY CONDITIONS, PASSING THUNDERSTORMS BUBBLED UP
AT TIMES AND RAINFALL WAS VERY EFFICIENT. FOR EXAMPLE, AT NEARBY
LIMA, OH, 2.02" OF RAIN WAS RECORDED ON THE 26TH BUT 1.92" OF THIS
TOTAL WAS RECORDED IN ONE HOUR! ALL TOLD, THE MONTH`S PRECIPITATION
TOTALED 4.25 INCHES WHICH IS 0.23 INCHES BELOW NORMAL. THIS RANKS AS
THE 51ST WETTEST JUNE ON RECORD. DESPITE BEING BELOW NORMAL, THIS IS
THE GREATEST AMOUNT OF JUNE RAINFALL SINCE 2021 WHICH RECORDED 5.91
INCHES.
...A HOT AND HUMID JULY...
LAST YEAR, WE ENJOYED A COOLER THAN NORMAL JULY WITH NO 90 DEGREE
DAYS. THIS YEAR, THE WEATHER WAS MUCH MORE TYPICAL FOR JULY WITH
MULTIPLE UPPER LEVEL RIDGES SETTING UP OVER THE MIDWEST AND GREAT
LAKES REGIONS. HOT AND HUMID WEATHER DOMINATED FOR A MAJORITY OF THE
MONTH, ESPECIALLY AT THE BEGINNING AND END OF THE MONTH. THERE WERE
9 DAYS WITH HIGH TEMPERATURES IN THE 90S IN FORT WAYNE. THE HOTTEST
TEMPERATURE THIS MONTH WAS 95 DEGREES ON JULY 24TH. AS FOR THE
HUMIDITY, THERE WAS A NOTICEABLE STRETCH OF VERY HUMID CONDITIONS
FROM JULY 24TH THROUGH 30TH. DURING THIS TIME, THERE WERE 106
CONSECUTIVE HOURS OF DEWPOINTS AT OR GREATER THAN 70 DEGREES! THIS
RUN IS THE LONGEST ON RECORD FOR DEWPOINTS AT OR GREATER THAN 70
DEGREES FOR JULY AND IS THE 5TH LONGEST STRETCH ON RECORD FOR ANY
MONTH OF THE YEAR. DEWPOINT DATA AT KFWA DATES BACK TO 1948.
OVERALL, JULY FINISHED WITH AN AVERAGE TEMPERATURE OF 76.5 DEGREES,
WHICH IS 2.7 DEGREES ABOVE NORMAL. THIS TIES 2002 AND 1919 AS
THE 18TH WARMEST JULY ON RECORD AND THE WARMEST SINCE 76.9 IN 2020.
AMID VERY HOT AND HUMID CONDITIONS, THUNDERSTORMS WERE WIDELY HIT OR
MISS IN AND AROUND FORT WAYNE THIS MONTH. RAINFALL WAS VERY
EFFICIENT FOR LOCATIONS THAT WERE ABLE TO GET STORMS. FOR INSTANCE,
ON JULY 30TH, HARLAN, IN RECEIVED OVER 4" OF RAIN (ON NE SIDE ALLEN
COUNTY, IN) WHILE THE FORT WAYNE AIRPORT ONLY GOT 0.08" (SW SIDE OF
ALLEN COUNTY, IN). THERE WERE ONLY 2 DAYS THIS MONTH WHERE DAILY
RAINFALL TOTALS WERE OVER A HALF INCH: JULY 25TH AND JULY 31ST. JULY
2025 HAD 2.15 INCHES OF RAIN THIS MONTH, WHICH IS 1.90 INCHES BELOW
NORMAL AND TIES (1995, 1932) AS THE 25TH DRIEST MONTH ON RECORD.
THIS WAS COMPARABLE TO 2.14 INCHES RECORDED IN JULY OF LAST YEAR.
OTHERWISE, THIS IS THE DRIEST JULY SINCE 1.12 INCHES IN 2016.
NO NEW RECORDS WERE SET THIS MONTH.
...A VERY DRY AND SLIGHTLY COOLER AUGUST...
THE BEGINNING OF AUGUST BEGAN WITH A FEW DAYS OF COOLER THAN NORMAL
TEMPERATURES, WHICH WAS FOLLOWED BY A LONGER RELATIVELY WARM PERIOD
THROUGH THE MIDDLE PART OF THE MONTH. THERE WERE 5 DAYS IN THE 90S
THIS MONTH WITH THE WARMEST TEMPERATURE OF THE MONTH OCCURRING ON
AUGUST 12TH WITH A HIGH OF 91 DEGREES. A UNSEASONABLY STRONG COLD
FRONT SWEPT THROUGH ON AUGUST 24TH/25TH, REPLACING THE HOT AND HUMID
CONDITIONS WITH MUCH COOLER TEMPERATURES FOR THE LAST THIRD OF THE
MONTH. THE LAST 9 DAYS OF AUGUST FEATURED HIGHS IN THE 70S AND LOWS
IN THE 40S. DAILY AVERAGE TEMPERATURE DEPARTURES WERE GENERALLY
SMALL EACH DAY, BUT DEPARTURES ON THE 26TH AND 27TH WERE OVER 10
DEGREES BELOW NORMAL. AFTER THE 2ND MOST HUMID JULY ON RECORD,
AUGUST WAS MUCH MORE COMFORTABLE IN TERMS OF HUMIDITY AND THE
OVERNIGHT LOWS. THERE WERE 4 NIGHTS IN AUGUST WITH A LOW OF 50 OR
LESS; THE COLDEST LOW TEMPERATURE OF THE MONTH OF 42 DEGREES
OCCURRED ON AUGUST 27TH. THIS LOW TEMPERATURE ACTUALLY SET A NEW
DAILY RECORD, BREAKING THE PREVIOUS RECORD OF 45 SET ON AUGUST 27,
1910. ALL IN ALL, AUGUST FINISHED WITH AN AVERAGE TEMPERATURE OF
70.7 DEGREES IN FORT WAYNE, WHICH IS 0.9 DEGREES BELOW NORMAL AND
TIES FOR THE 38TH COOLEST AUGUST ON RECORD.
MUCH LIKE JULY, PRECIPITATION WAS VERY HIT OR MISS. MUCH OF THE
MONTH`S RAINFALL TOTAL CAME FROM POP-UP SHOWERS AND STORMS AS THE
AFOREMENTIONED STRONG COLD FRONT TOWARDS THE END OF THE MONTH DID
NOT PRODUCE ANY SUSBSTAINIAL RAIN. IN FACT, UP UNTIL AUGUST 28TH,
FORT WAYNE WAS IN THE RUNNING FOR THE 2ND DRIEST AUGUST ON RECORD. A
TOTAL 0.73" OF RAIN FELL ON AUGUST 28TH, WHICH ACCOUNTS FOR OVER
HALF OF THE RAINFALL FOR THE ENTIRE MONTH AND BOOSTED THE MONTHLY
TOTAL OVER AN INCH. AUGUST TOTALED 1.16" OF RAIN FOR THE MONTH,
WHICH IS 2.51" BELOW NORMAL. THIS WAS THE DRIEST AUGUST IN FORT
WAYNE SINCE 1984.
