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
EIGHT DAYS WITH HIGH TEMPERATURES IN THE 90S IN SOUTH BEND. THE
HOTTEST TEMPERATURE THIS MONTH WAS 96 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
64 CONSECUTIVE HOURS OF DEWPOINTS AT OR GREATER THAN 70 DEGREES.
THIS RUN IS THE 11TH LONGEST WITH DEWPOINTS AT OR ABOVE 70 DEGREES
FOR JULY. DEWPOINT DATA AT KSBN DATES BACK TO 1948. ONE RECORD WARM
LOW TEMPERATURE WAS TIED THIS MONTH. ON JULY 24TH, THE LOW OF 74
DEGREES TIED THE PREVIOUS DAILY RECORD SET IN 1987. OVERALL, JULY
FINISHED WITH AN AVERAGE TEMPERATURE OF 75.9 DEGREES, WHICH IS 3.5
DEGREES ABOVE NORMAL. THIS MONTH TIES 1949 AS THE 19TH WARMEST JULY
ON RECORD AND THE WARMEST SINCE 76.4 DEGREES IN 2020.
AMID VERY HOT AND HUMID CONDITIONS, THUNDERSTORMS WERE WIDELY HIT OR
MISS IN AND AROUND SOUTH BEND THIS MONTH. RAINFALL WAS VERY
EFFICIENT FOR LOCATIONS THAT WERE ABLE TO GET STORMS. FOR INSTANCE,
ON JULY 20TH, A NEARBY COCORAHS OBSERVER IN MILL CREEK, IN IN LA
PORTE COUNTY REPORTED 2.94" OF RAINFALL WHILE THE SOUTH BEND AIRPORT
ONLY GOT A TRACE. THERE WERE ONLY TWO DAYS THIS MONTH WHERE DAILY
RAINFALL TOTALS WERE OVER A HALF INCH: JULY 26TH AND JULY 28TH. JULY
2025 HAD 3.04 INCHES OF RAIN THIS MONTH, WHICH IS 0.74 INCHES BELOW
NORMAL AND RANKS AS THE 65TH DRIEST MONTH ON RECORD. THIS WAS THE
DRIEST JULY IN SOUTH BEND SINCE 2.39 INCHES IN 2021.
