HeatSafe WBGT

Know when heat becomes dangerous. HeatSafe shows live Wet Bulb Globe Temperature and clear, color-coded safety guidance for your exact location.

HeatSafe turns complex heat science into a simple answer: how dangerous is the heat right now, and what should you do about it?

Most weather apps only show temperature. But how hot it feels — and how risky it is for your body — depends on humidity, sun, and wind too. HeatSafe uses Wet Bulb Globe Temperature (WBGT), the same heat-stress measure trusted by athletic trainers, the military, and outdoor workers, to give you a clear read on real heat risk.

FEATURES • Live WBGT estimate for your current GPS location • Clear, color-coded risk levels with plain-language safety guidance • Hourly outlook so you can plan workouts, games, and outdoor work • Save your favorite locations and check conditions anywhere • Works worldwide using Open-Meteo forecast data, with extra detail from the National Weather Service in the United States • Fast, lightweight, and privacy-friendly — no account required

WHO IT'S FOR • Athletes, coaches, and parents at youth sports • Runners, hikers, cyclists, and golfers • Outdoor and construction workers • Anyone who wants to stay safe when it's hot and humid
