I know it should be useful to very few people from here, but I'll be happy if it helps one person :)

Collecte MTL is an app (web and iOS) to know waste collection schedule at any address on Montreal island.

It uses open data provided by the city (which is great!), and is totally free and without ads.

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!
