Why temperature is not enough
A temperature reading is a lousy way to know whether you will like being outside. 85 degrees in dry shade can feel fine. 85 degrees in heavy humidity and direct sun can feel brutal. Humidity, sun, and wind all change how heat hits your body, but most apps still hand you one number and make you do the math.
Comfort Predictor does that work for you. It blends temperature, humidity, sun, and wind into one measure of how the air will feel, then shows the times when conditions are comfortable today, over the next few days, and across the week. Instead of "85 and humid," you get "comfortable from 7-9am, then again after 6pm."
It is built for anyone planning time outdoors: a walk, a run, gardening, a kid's playtime, a dog walk, or lunch outside. The point is simple: pick the right window, not just the right temperature.
