Prepare for hot weather before it arrives

A simple heat plan can help households make safer choices when high temperatures are forecast.

Check local forecasts and alerts

Heat risk depends on temperature, humidity, exposure, housing and a person's circumstances. Follow alerts from your local weather service and public-health authority, because thresholds and recommended actions vary by region. CDC heat-health information offers general protective steps, but local directions should take priority during an emergency or an official heat advisory.

Plan shade, rest and contact

Think ahead about access to a cooler place, drinking water appropriate for your needs, and ways to reduce strenuous activity during the hottest part of the day. Check in with people who may have limited cooling, mobility or social support. Fans and air-conditioning availability differ; local authorities can provide options such as cooling centers when those services exist.

Know when to seek help

Heat-related illness can become urgent. Learn warning signs and emergency steps from your public-health authority, and contact emergency services if someone is seriously unwell. Some medicines and health conditions affect heat risk; do not alter a prescription without professional advice. CDC guidance is U.S.-focused, so use the relevant local health service for emergency numbers and current recommendations.
