I calculated sun/shade exposure for every seat at World Cup stadiums
Last year, I went to a game at a stadium I had never visited (Arrowhead). Ended up baking in the sun for the entire second half. Afterwards, was surprised I couldn't find a tool that told me where the sun would actually be during games. So for WC2026 I built SeatSun: a free tool (no sign up needed) that calculates sun/shade exposure for every section at the World Cup 2026 stadiums depending on date and match time. The technical core: solar azimuth and altitude calculations (based on Meeus astronomical algorithms, ~0.3 degree accuracy) tied to each stadium's orientation and GPS…

A map of cafes that are in the sunJul 2026 · sunny.coffee · ▲8I wanted to sit outside for coffee but there was no way to see which cafes are in the sun right now. So I built a map that shows which cafes, benches, and outdoor seats are in the sun vs. shade at any time of day. It ray-marches building shadows live in a WebGL shader over a MapLibre map. I also pre-index all places from OpenStreetMap into H3 hex cells and serve them as static JSON on Cloudflare R2, so the client just fetches the cells in view and no backend is needed. Feedback welcome, especially on shadow accuracy in your city. Currently only buildings and trees are taken into account when…
