Wet Bulb Globe Temperature

Wet Bulb Globe Temperature helps you understand current and forecast heat risk for a location you choose. See the WBGT estimate, risk band, source, freshness, practical planning guidance, hourly outlook, and map context in one calm view.

CHECK HEAT RISK

• Review current WBGT and its clearly labeled risk band.
• See when the estimate was valid and which weather source supplied it.
• Compare hourly and multi-day conditions before work, exercise, or an event.
• Explore a location on the map without silently changing a saved place.
• Keep the last valid result visible when a refresh fails.

USE OFFLINE HEAT TOOLS

The Calc tab works without location or network access. Calculate outdoor WBGT, indoor or shade WBGT, estimated wet-bulb temperature, dew point, relative humidity, or heat index from values you provide. Each method shows only the inputs it needs and keeps its result separate from weather history.

FREE CORE, OPTIONAL PRO

The free app includes core WBGT guidance, offline calculators, up to five saved locations, recent saved forecasts, and a daily allowance for fresh worldwide weather locations. When the allowance is used, an optional rewarded ad can add more fresh checks after verification.

Pro adds unlimited saved locations and history, CSV export, forecast-day reminders, higher paid-provider allowances, and removes ads. Weekly, monthly, annual, and lifetime options are available.

PRIVATE BY DESIGN

No account is required. Saved sites, history, preferences, and reminder settings remain on your device. Location is optional and requested only when you choose automatic nearby weather.
