## What is WetBulb?

Know when outdoor heat deserves extra caution.

WetBulb-Guard turns temperature and humidity into a clear, easy-to-read heat-risk check. See an estimated wet-bulb temperature, heat index, and the lower-risk hours ahead before you head out.

PLAN OUTDOOR TIME
• Check current heat risk for your location or any city
• Compare the next 12 hours to find a cooler window
• Choose an activity type for practical, general planning guidance

SEE THE NUMBERS THAT MATTER
• Temperature and relative humidity
• Heat index
• Estimated wet-bulb temperature
• Clear data time and stale-data status

STAY IN CONTROL
• Optional alerts when your chosen risk level is forecast
• Use your location or search for a city
• No account, ads, subscription, or in-app purchases

Important: WetBulb-Guard provides general weather information and estimates for personal planning. It does not measure on-site WBGT, replace an employer heat-safety plan, provide medical advice, or determine whether conditions are safe for any activity. Check local conditions and seek professional or emergency help when needed.
