San Francisco, known for its microclimates and unpredictable weather, is experiencing a typical November day today, November 17, 2025. The city is waking up to a crisp morning with temperatures hovering around 55°F (13°C).
San Francisco's weather is heavily influenced by its proximity to the Pacific Ocean, resulting in a Mediterranean climate with mild, wet winters and dry, cool summers. Today, the city is experiencing the classic San Francisco fog, which is a common occurrence this time of year. The fog, known locally as "Karl the Fog," often rolls in from the ocean, creating a mystical atmosphere that is both beloved and frustrating for residents.
The weather forecast for the rest of the day predicts a high of 62°F (17°C) with a mix of sun and clouds. The wind is expected to pick up slightly in the afternoon, with gusts reaching up to 15 mph, adding a bit of a chill to the air. The humidity will remain relatively high, typical for a coastal city, making it feel a bit cooler than the actual temperature.
For those planning outdoor activities, it's advisable to dress in layers. A light jacket or sweater will be essential for the morning and evening hours, while the midday sun might make a lighter layer more comfortable. The fog is expected to lift somewhat by mid-afternoon, offering a few hours of clearer skies before it returns in the evening.
San Francisco's weather is a significant part of its charm, and today is no exception. The city's unique climate, with its foggy mornings and mild afternoons, creates a dynamic atmosphere that keeps residents and visitors on their toes. Whether you're a local or a tourist, understanding the weather patterns of San Francisco can enhance your experience and help you make the most of your day.
