INDIANAPOLIS, INDIANA — Indiana is experiencing what meteorologists are calling the hottest day of the year, and the numbers hitting the state today are not just uncomfortable — they are dangerous.
Heat index values are soaring across every corner of Indiana on June 30, 2026, with no city, town, or region escaping the extreme conditions. New Albany, in the far south, is leading the entire state with a heat index of 111 degrees — a number that pushes well past the threshold where heat-related illness becomes a serious, life-threatening risk.
The extreme heat is not limited to southern Indiana. Vincennes and Evansville are both reaching 109 degrees on the heat index, while Terre Haute climbs to 108. Indianapolis, the state capital, is sitting at 106 degrees. Even the northern communities that typically stay cooler are getting hit hard — Fort Wayne is recording 107, Gary and Lafayette are at 106, and South Bend is at 104.
What makes today different from a typical summer heat event is the statewide uniformity. From the Michigan border all the way down to the Ohio River, every reporting location in Indiana is sitting above 100 degrees on the heat index. There is no cooler corner of the state to escape to today.
Health officials are urging Indiana residents to stay indoors in air conditioning for as much of the day as possible. Outdoor activity should be avoided during peak afternoon hours. Those who must be outside are advised to take frequent breaks in shaded areas, drink water consistently, and monitor themselves and others for warning signs of heat exhaustion — including heavy sweating, dizziness, nausea, and rapid heartbeat.
Elderly residents, young children, and those without access to air conditioning face the greatest risk today. Neighbors are being asked to check in on vulnerable community members.
Indiana has seen hot summers before. But today, June 30, 2026, stands out as a statewide emergency-level heat event.
