SF has microclimates and for my preferences the southeastern part of the city (the Mission, Potrero Hill, Dogpatch) have perfect summers. Highs of 65-75, and then at night the fog comes and cools things down for perfect sleep temperatures. On the western side of the city it’s just fog all day. Plus it’s always an impressive sight to see the fog come over the hills every day.
