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 Montgomery because deep South heat and Black Belt humidity make this capital's summers punishing, with wet-bulb readings running dangerously high. 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 Montgomery usually gets
Across 2015–2024, Montgomery averaged a 91°F daily high in summer: 47th hottest of the 174 metros we track, and July is typically the warmest month.
Summer runs warm rather than extreme: about 73 days a year reach 90°F, and 100°F is essentially unheard of.
Humidity is the real story: summer averages about 71%, so sweat evaporates poorly and heat stress runs well above what a 91°F afternoon suggests.
It rarely strays far above its own average, topping out at 100°F in this sample.

For school sports, AHSAA (Alabama High School Athletic Association) publishes AHSAA Heat Stress Exercise Restrictions (updated 28 May 2024), which uses wet-bulb globe temperature. Alabama’s activity zones appear beside the live reading in the app.
Heat in Montgomery: common questions
How hot does it usually get in Montgomery?
Across 2015–2024, Montgomery averaged a 91°F daily high through summer, with about 73 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 Montgomery?
July has the highest average daily high in Montgomery. Humidity is the real story here: summer averages about 71%, 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 Alabama have a heat policy for school sports?
AHSAA (Alabama High School Athletic Association) publishes AHSAA Heat Stress Exercise Restrictions (updated 28 May 2024), which uses wet-bulb globe temperature. Alabama’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 Montgomery right now?
The reading at the top of this page is the current wet-bulb globe temperature for Montgomery, Alabama, 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 Montgomery?
Air temperature ignores humidity, wind, and sun: the things that decide whether heat is dangerous. Montgomery's climate (deep South heat and Black Belt humidity make this capital's summers punishing, with wet-bulb readings running dangerously high.) 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 Montgomery?
July is the peak month in Montgomery, and within a day heat stress is highest in the early-to-mid afternoon when sun load is greatest. About 73 days a year reach 90°F, so most of the risk sits in a handful of afternoons rather than across the whole season. Use the forecast on this page to find the window that works.
