T-Shirt Weather. See the multi-day forecast for any city on a world map

Hacker News

My family and I were trying to plan a short summer escape from the cold, grey Danish summer — somewhere it was actually warm enough for a t-shirt. I couldn't find a good way to just see that at a glance, so I built one. It's a world map of multi-day forecasts. Zoom out for capitals, zoom in and smaller cities fill in. There's a "t-shirt weather" toggle that highlights the places that are warm and dry enough for just a T-shirt. It's proven quite useful for us. Data is from Open-Meteo, city data from GeoNames. The stack is Nuxt + MapLibre GL, with fairly heavy Redis caching so I'm not hammering Open-Meteo on every pan/zoom. Hope someone else finds it useful. Have a great summer!
