Knowing about clothing essentials, bringing layers is crucial. Start with lightweight base layers, such as t-shirts or long-sleeved shirts, that can be easily added or removed as the temperature fluctuates. A light jacket or sweater is a must for evenings or cooler days. A slightly heavier jacket, such as a fleece or windbreaker, is also a good idea, especially if you plan to visit areas near the ocean or take a boat tour.

Additionally, consider location-specific needs within San Francisco. If you plan to visit areas near the coast, such as Fisherman's Wharf or Ocean Beach, be prepared for cooler temperatures and potential wind.
