Indianapolis, Indiana – Sweltering heat is set to blanket Indianapolis through the weekend, with temperatures soaring into the low 90s and only minor relief at night. By Friday, much of Central Indiana will see daytime highs of 90 to 92 degrees, prompting concerns for outdoor plans and those sensitive to the heat.
According to the National Weather Service, patchy fog could linger early Thursday, but sunshine quickly takes over with a calm wind and highs near 89. Conditions stay mostly clear overnight, and Friday marks the start of a multi-day heat stretch as south winds gradually increase humidity and keep nighttime lows around 72.
Sunny, hot weather dominates both Saturday and Sunday, with peak temperatures near 92 on Saturday and 91 Sunday. Little cloud cover means UV levels will be high, so limit afternoon exposure and keep hydrated. Southwest breezes will offer limited relief as warm air persists across the metro and outlying counties.
The next notable change comes Monday, when there’s a 20% chance of showers and thunderstorms after 2 p.m., offering the first break from relentless heat. Until then, plan for hot days, mild nights, and little rain in sight. Stay alert for additional heat advisories and be ready for developing thunderstorm risks as early as late Monday.
