Is it safe to be outside right now? The thermometer only knows half of it. Standing in open sun is not the same as standing in the shade, so HeatCue reads both: wet-bulb globe temperature (WBGT), the number that captures how heat, humidity, and sun actually hit your body, with a plain risk band you can read in a second. Know before you go: • Current WBGT for your location: heat, humidity, and sun in one number • Sun or shade: the same weather read two ways, so you know what the shade buys you • A clear risk band: Safe / Caution / Danger / Extreme • UV index beside the heat: sunburn risk at a glance • Alerts: your cue before conditions turn dangerous, several per place, each watching sun or shade • Home-screen widgets: conditions at a glance • Hourly + 7-day forecast and trends: plan the run, the hike, the walk • Multiple locations: home, work, the trailhead • Profiles: the average person, at-risk people, and dogs each have different heat limits. You can also create a custom profile. • Plain-language guides: what wet bulb and WBGT actually mean Built for anyone who works, trains, or plays outside, and for anyone keeping an eye on kids, older family, or pets through a heatwave. HeatCue shows conditions and general risk categories based on public weather data.
