On a clear day in June the terrace has sun 11:00–14:00, about 3 hours in total. In short: sun at lunch.
The story of Hermans
Hermans is a vegetarian restaurant at Fjällgatan 23B on Södermalm. Its founder, Herman Ottosson, came up with the idea while selling home-made jewellery on Mexican beaches. Back in Stockholm he set out to bring vegetarian food to the city, opening his first restaurant in 1992; over time it grew to seven around town.
After fourteen years in the trade, Herman handed the vegetarian kitchen over to Leo and Omer in 2006. The restaurant describes itself as a multicultural extended family with staff from all over the world, and from Fjällgatan the view stretches out across Stockholm.

How Stoligt works it out
Every ten minutes we draw a line from each terrace toward the sun and check whether a building or hill is tall enough to block it. Building heights come from OpenStreetMap and ground heights from Lantmäteriet, the Swedish mapping agency. The times assume a clear day, so clouds are not included here. They are on the live map, which shows today's weather.
Trees, parasols and awnings are not in the model, and we don't know exactly where on the pavement the tables stand. Treat the times as an educated guess, often accurate to within ten minutes.
