What Should I Wear Today? — WhetherWear

What to wear today depends on more than the temperature: wind, rain, sun and how long you will be outside all move the answer, and two people in the same weather can correctly dress differently. WhetherWear reads the live conditions for your location and returns a specific outfit — layers, outerwear, footwear and what to carry — adjusted for your activity and whether you run warm or cold.

How to dress for the weather today

Air temperature alone is a poor guide to what to wear. The same 55°F is a different decision in still sun than in a 20 mph wind, and the gap between the two is often larger than the gap between two forecast days. WhetherWear reads the conditions that actually change the answer:

Feels-like, not air temperature. The correction that matters changes with the season, and neither one runs the whole year. Below roughly 50°F wind chill governs, because moving air strips away the thin warm layer your body holds against your skin — that is the domain the NWS wind chill formula is defined on. In real heat, from roughly 80°F, humidity governs instead, because it decides whether sweat can evaporate at all; that is where the NOAA heat index begins. Between the two the air temperature is close to the whole story, and a large “feels like” correction in that band deserves suspicion rather than trust.
How long you will be outside. Five minutes and three hours at the same temperature are different garments.
Sustained wind, never the gust. Wind is a construction problem before it is an insulation one — a dense weave or a membrane beats another sweater.
Measured precipitation and its probability, rather than hedged forecast wording. Text like “patchy rain possible” is a hint, not rain.
Dew point for breathability. Relative humidity cannot tell you whether sweat will evaporate; dew point is that gap expressed as a temperature.
Whether you run warm or cold, and what you are doing. Two people in the same weather can correctly dress differently.

What it does not know is stated too: indoor conditions, your health, and what is actually in your wardrobe. The full method, including what is deliberately not published, is at how WhetherWear decides. No measured accuracy rate is claimed.
