Is Dolores in the sun right now? Will that patio still be sunny at 5? Sunny Spots SF answers the one question San Francisco weather apps can't: not whether it's sunny — but WHERE. The app simulates real building shadows for any time of any day. Drag the time slider and watch shadows creep across the city, computed from actual building geometry and the sun's true position. Blend in live hourly cloud forecasts, and every park, café, and beach in the city gets an honest sun score — full sun, good sun, low sun, in shadow, or fogged out. WHY IT'S DIFFERENT • Real shadow simulation — not just a weather forecast. The app knows which side of the street the sun is on. • Built for San Francisco's microclimates — the city where it's 58° and foggy in the Sunset while the Mission bakes. • 1,300+ spots — cafés with outdoor seating, parks, coworking spots, and all 9 city beaches, refreshed live from OpenStreetMap. FEATURES • Time-travel slider: check sun for any time today, tomorrow, or any date • Live cloud, wind, and UV forecasts for every beach, with the best tanning window for the next 3 days • Verified sunny spots, ground-truthed by locals • Filter by parks, cafés, work spots, and beaches • Works instantly — no account, no sign-up, nothing to configure PRIVATE BY DESIGN No accounts, no analytics, no ads, no tracking. Location permission is optional and your location never leaves your phone. Sun position math based on the SunCalc algorithms. Location data © OpenStreetMap contributors. Weather data by Open-Meteo.com. Maps by Apple.
