If you're planning outdoor activities in San Francisco, ignore the season — focus on the hour. I hiked Lands End in July at 2pm in a t-shirt and was shivering by 4pm when the fog rolled in. The 5°C temperature swing between coast and bay is real. Best running conditions: September-October, when the marine layer retreats and 22°C hits the city. Pack a windbreaker for any coastal trail, year-round. Marin Headlands is magnificent but windy; aim for 10am-2pm. February-March brings surprisingly green hills and empty trails — my favorite hiking window.
