Detailed Profiles of Each Record Extreme
🌡️ All-Time High Temperature: 98.0°F
August 11, 2023 • 10-Year Average High: 83.2°F
During the peak of the 2023 persistent subtropical ridge, temperatures at Tampa International Airport climbed to 98.0°F—nearly 15°F above the 10-year average daily high (83.2°F) and marking the hottest single reading across the entire 10-year observational period. Combined with a dew point near 80°F, heat index values exceeded 115°F.
❄️ All-Time Low Temperature: 29.0°F
December 24, 2022 • 10-Year Average Low: 68.3°F
A historic arctic outbreak drove sub-freezing polar air deep into peninsular Florida on Christmas Eve 2022. KTPA bottomed out at 29.0°F—almost 40°F colder than the typical 10-year average low (68.3°F), recording a hard freeze and setting the coldest temperature of the 2015–2024 decade.
💧 Peak Atmospheric Dew Point: 82.0°F
August 7, 2024 • 10-Year Average Dew Point: 64.2°F
Dew points exceeding 75°F are considered oppressive; on August 7, 2024, deep tropical moisture over Tampa Bay surged the dew point to 82.0°F, nearly 18°F above the 10-year baseline average (64.2°F). This saturated atmosphere trapped heat at ground level and delivered record atmospheric moisture content.
🌪️ Lowest Barometric Pressure: 28.69 inHg
September 10, 2017 • 10-Year Average Pressure: 30.04 inHg
As Hurricane Irma tracked northward through the Florida peninsula, its central core induced a dramatic atmospheric pressure collapse. KTPA’s barometer plummeted from its typical 30.04 inHg baseline down to 28.69 inHg (971.5 hPa), the lowest barometric pressure recorded in the 10-year period.
💨 Peak Sustained Wind: 47.0 mph
September 10, 2017 • 10-Year Average Peak Wind: 13.5 mph
The strongest 2-minute sustained wind speed recorded across the 10-year period reached 47.0 mph during Hurricane Irma’s closest approach—more than triple the typical daily peak sustained wind (13.5 mph), accompanied by peak instantaneous wind gusts of 66 mph at airport anemometers.
🌧️ All-Time Wettest Day: 16.14 Inches
August 4, 2024 • 10-Year Average Daily Rain: 0.36 in
Slow-moving tropical moisture feeder bands associated with Hurricane Debby dropped an astounding 16.14 inches of rain in a single 24-hour observational cycle at KTPA—nearly 45 times the typical daily rainfall (0.36 in), shattering all previous 10-year daily rainfall records.
