Features & Capabilities

WetBulbCast shows forecasts of wet-bulb temperature to check whether your swamp cooler will work well for you.

Is it a good day for your swamp cooler? Your evaporative (swamp) cooler cannot cool the air it blows into your house to below the wet bulb temperature — and how well they work depends almost entirely on one number: the wet-bulb temperature. When it's low, your cooler can drop indoor temperatures dramatically and cheaply. When it's high, running it barely helps. What you get
: • Wet-bulb temperature — the single most important number for swamp cooler effectiveness, shown for every hour of the next 10 days 
 • Dew point — a direct measure of how much moisture is already in the air
 • Feels-like temperature — so you know what it's actually like outside, not just what the thermometer says
 • 10-day hourly forecast — plan your cooler schedule days ahead and whether you may need AC instead 
 • UV index, wind speed, precipitation probability, and cloud cover — the full picture in one compact table
• Interactive chart — visualize temperature, wet-bulb, and dew point trends at a glance 
 • Multiple saved locations — check your home, office, or any place you care about Powered by Apple Weather
 WetBulbCast uses Apple's WeatherKit for accurate, hyperlocal forecasts updated throughout the day.
