Heat stress in Providence
Coastal New England humidity feeds muggy summer heat that lingers, and older triple-decker housing often lacks the AC to cope.

Wet-bulb globe temperature (WBGT) is the heat measure that actually tracks danger to the body. Unlike the plain air temperature on your phone, it folds in humidity, wind, and direct sun: the factors that decide whether your sweat can still cool you. It’s the standard the military, athletic associations, and occupational-safety bodies use to call when outdoor activity is no longer safe.
That matters in Providence because coastal New England humidity feeds muggy summer heat that lingers, and older triple-decker housing often lacks the AC to cope. The number above is the live outdoor WBGT for the city right now; tap through to the live map to inspect any neighborhood, scrub the forecast hour by hour, and see the 7-day outlook.
How hot Providence usually gets
Across 2015–2024, Providence averaged a 81°F daily high in summer: 149th hottest of the 174 metros we track, and July is typically the warmest month.
Heat arrives in bursts here rather than settling in, with only about 9 days a year at or above 90°F.
Humidity is the real story: summer averages about 73%, so sweat evaporates poorly and heat stress runs well above what a 81°F afternoon suggests.
A bad day runs well past a normal one, with 100°F recorded against a 81°F summer average.
Daily high temperatures and humidity from ERA5 reanalysis, 2015–2024 (hottest day in the sample: 2022-08-09). These are climate averages for context: the reading at the top of this page is the live one.
For school sports, RIIL (Rhode Island Interscholastic League) publishes RIIL Rules & Regulations, Article 7 §3: Heat Acclimatization Rules, which uses wet-bulb globe temperature. Rhode Island’s activity zones appear beside the live reading in the app. Our Rhode Island heat policy page has the details, the source and the date we last checked it.
Heat in Providence: common questions
How hot does it usually get in Providence?
Across 2015–2024, Providence averaged a 81°F daily high through summer, with about 9 days a year at or above 90°F. July is typically the hottest month, and the hottest day in that sample reached 100°F. Figures are from ERA5 daily reanalysis.
When is the hottest time of year in Providence?
July has the highest average daily high in Providence. Humidity is the real story here: summer averages about 73%, so sweat evaporates poorly and heat stress runs well above what the temperature alone suggests. Use the forecast on this page to plan around the specific days that matter.
Does Rhode Island have a heat policy for school sports?
RIIL (Rhode Island Interscholastic League) publishes RIIL Rules & Regulations, Article 7 §3: Heat Acclimatization Rules, which uses wet-bulb globe temperature. Rhode Island’s activity zones appear beside the live reading in the app. Our WBGT is a modeled estimate rather than the on-site device reading a policy may call for, so check the association's own document for current requirements.
What is the WBGT in Providence right now?
The reading at the top of this page is the current wet-bulb globe temperature for Providence, Rhode Island, computed from live weather by the Liljegren (2008) method and labeled with how recently it updated. For an exact reading at your own neighborhood, plus an hour-by-hour forecast, open the live map.
Why is WBGT more useful than the temperature for Providence?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Providence's climate (coastal New England humidity feeds muggy summer heat that lingers, and older triple-decker housing often lacks the AC to cope.) is exactly why a single "feels-like" or thermometer reading can understate the real risk. WBGT captures all of it in one number.
When is heat most dangerous in Providence?
July is the peak month in Providence, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. Dangerous days are uncommon here, which is its own hazard: 9 days a year reach 90°F, and people are least acclimatized when they arrive. Use the forecast on this page to find the window that works.
