Sun Trap: Pub Sun Finder

Sun's out. Suntrap shows you, right now, which UK pub gardens are actually lit — and which will still be in the sun by the time you walk over.

Suntrap finds UK pubs whose beer garden, terrace or pavement seating is actually in the sun right now — or whenever you're planning to head out.

For every pub we know about, Suntrap traces the outdoor space, then casts the sun against the surrounding buildings to work out how much of the seating is lit at this moment. No guesswork, no "south-facing" hand-waving — just a map of where the sun has actually landed.

Features • A live map of pubs, each tinted by how sunny their outdoor space is right now. • A sun-time slider — drag forward an hour or two to see where the light will be by the time you arrive. • Tap a pub for opening hours, a photo of the outdoor area, and walking directions. • Switch cities in a tap. Suntrap is live across a growing list of UK cities — London, Manchester, Birmingham, Liverpool, Leeds, Bristol, Brighton, Edinburgh, Glasgow, Cardiff, Belfast and more — with new ones added regularly. • Works offline-friendly: tiles cache as you pan, so the map keeps moving on patchy signal. • No accounts, no tracking, no ads.

How it works Suntrap combines OpenStreetMap pub and building data with first-principles solar geometry. For each pub we sample points across the outdoor seating polygon, raycast toward the sun, and check whether any nearby building is tall enough to block it. The lit fraction is weighted by sun altitude, so a bright noon sun counts for more than a low evening one.

Suntrap is independent. We start from OpenStreetMap data and then hand-trace the gardens and street seating that OSM doesn't cover yet — so if a garden is missing or wrong, tap "Send feedback" inside the app and we'll add it.
