Jacket or Not?
Do I need a jacket today?
Jacket or Not? pulls your local forecast (temperature, feels-like, wind, and sunset) and gives you a single call: wear it, bring it, or leave it. No five-day chart, no radar. Just the one answer you actually need before walking out the door.
How the call is made
- Feels-like under 58°F (14°C) locks in a "wear" verdict, no matter the air temperature.
- Evening temperature drops shift a "leave" into a "bring" so you are not stuck out at sunset without a layer.
- Wind chill is folded into feels-like, so a windy 65°F day can read colder than a still 60°F one.
Common questions
What temperature do I need a jacket?
Jacket or Not? triggers a "wear" verdict when feels-like temperature is at or below 58°F (14°C). Between roughly 58°F and 70°F (14°C to 21°C) you may want to bring a layer for later. Above that, you can leave it home.
Should I bring a jacket if it is windy?
Yes, often. The verdict factors in wind chill, not just air temperature. A 65°F day with 20+ mph wind can feel cold enough to flip the call from "leave" to "bring" or "wear".
Does Jacket or Not? use my location?
It pulls a forecast for the location you grant or type in (city or ZIP). Your coordinates are only used to fetch weather data. Nothing is stored on a server tied to you. The full policy is on the privacy page.
Why does it sometimes say "bring" instead of "wear"?
"Wear" means you need a layer right now. "Bring" means you do not need it walking out the door, but the temperature drops, wind picks up, or sunset is coming and you will likely want one later. It is a contingency, not the same call.
