Wet Bulb Temperature Tracker vs Earth Exhibit

High Wet Bulb Globe Temperature (WBGT) days are more common each year. This free Wet Bulb Tracker sends you alerts and keeps you informed. Plan your activities for the day, at work or with family, with your health and safety in mind. Air Temperature is about hot air. Wet Bulb Temperature measures humid-heat conditions to indicate how much your body can cool without help, when active outdoors. Our body runs at about 36°C / 97°F, so a Wet Bulb of 30°C / 86°F feels uncomfortably warm, and by 35°C / 95°F the body dangerously overheats. THE OUTDOOR READING, FRONT AND CENTRE Wet Bulb is usually read off instruments in the field, but mathematical models let us work it out from weather data for a location. Wet Bulb Globe Temperature (WBGT) is calculated in the app from air temperature, humidity, sun, and wind. Calculations follow the US National Weather Service's forecast method: a psychrometric solve for Wet Bulb, and the Dimiceli and Piltz globe model. This reading is useful when working, training, or walking outside, as a heat risk warning. WET BULB MATH ANSWERS A DIFFERENT QUESTION FROM 'FEELS LIKE' Feels Like answers: how hot does the air feel? A Feels Like of 32°C / 90°F is just a warm day. Wet Bulb Globe answers: how much can sweating cool you outdoors? A Wet Bulb Globe of 32°C / 90°F is Critical, and tells you to immediately stop exertion outside and stay actively cool. It matters. HEAT ALERTS Alerts notify you when outdoor Wet Bulb rises at your location. Adjust alerts in Settings. SEE A WHOLE DAY'S TIMELINE View an hourly timeline of each day's Wet Bulb Globe temperature, colored by safety level, showing how humid-heat builds and fades. Drag the marker across the day and the readings above it change. Hours likely to see rain show a smaller bar giving the percentage chance in your area. KNOW WHAT TO DO Every risk level comes with basic but handy Guidance: how long it's reasonable to stay out, what to watch for, and when to take breaks. The About page links to the Wet Bulb thresholds used by militaries, occupational safety bodies, and national weather services worldwide. WORK IT OUT - GET AN UNDERSTANDING The Calc tab lets you slide in any air temperature, humidity, wind speed, and solar radiation and watch both readings respond. Useful for teaching the concept or calculating from data.

The sky and the seasons are always doing something remarkable. You just rarely hear about it in time. Earth Exhibit fixes that. Track 600+ natural phenomena from around the world: auroras, solar and lunar eclipses, meteor showers, wildlife migrations, wildflower blooms, bioluminescent tides, tidal bores, and dozens of atmospheric optics like sun dogs, fire rainbows, and light pillars. For each one, Earth Exhibit tells you the thing that actually matters. Is it worth stepping outside for near you right now, and if not now, when. WHAT YOU GET • A live read on what's happening near you, scored from real weather, moon phase, darkness, tides, space weather, and seasonal timing, not guesswork. • A Field Clock that answers "what's worth going outside for today, and when": golden hour, the clear-sky window, tonight's best stargazing, and any sky events. • Alerts when something you're watching is genuinely coming together. A geomagnetic storm pushing the aurora south, a meteor shower peaking under clear skies, a seasonal window opening near you. • A Coming Soon view of upcoming eclipses, conjunctions, and seasonal events with real dates and countdowns. • Detailed guides for every phenomenon: where to go, the best time of day, what conditions you need, and what to expect. • A way to log what you've seen, with photos and notes, and browse what others spotted. BUILT ON REAL DATA Earth Exhibit pulls from trusted public sources, including NOAA space-weather feeds, Open-Meteo forecasts, astronomical models, and wildlife observation databases, and combines them into one honest answer per phenomenon. When it tells you something is worth seeing, that is because the conditions actually support it.
