May in San Francisco is a delightful time, characterized by gradually warming temperatures and fewer rainy days as the city transitions from spring to early summer. This month offers a sweet spot for visitors, providing pleasant conditions ideal for exploring the city's iconic landmarks and vibrant neighborhoods before the peak summer crowds arrive. San Francisco weather during this period is often mild and inviting.
Understanding San Francisco's May Climate
Typically, San Francisco weather in May is characterized by moderate temperatures and relatively low rainfall. The average high temperature hovers around 65°F (18°C), while the average low dips to about 53°F (12°C). Despite these averages, San Francisco is known for its microclimates, meaning the weather can vary significantly from one neighborhood to another. For example, areas closer to the coast may experience cooler temperatures and fog, while inland areas like the Mission District tend to be warmer and sunnier. It is important to stay updated with accurate weather forecasts.
Fog, famously known as Karl the Fog, is a common phenomenon in San Francisco, especially during the summer months, but it can also make appearances in May. The fog forms as warm air from inland California meets the cold waters of the Pacific Ocean. This can lead to dramatic shifts in temperature and visibility, sometimes within the same day. Visitors should be prepared for the possibility of fog, particularly in the morning and evening, and dress in layers to adjust to the changing conditions.
Rainfall in May is generally minimal compared to the winter months. On average, San Francisco sees about 0.8 inches of rain in May, spread out over a few days. This makes it a relatively dry month, perfect for outdoor activities. However, it's always a good idea to check the forecast before heading out and carry a light jacket or umbrella just in case.

Humidity levels in San Francisco are typically moderate in May, adding to the overall comfort of the weather. The combination of mild temperatures and moderate humidity makes it easy to spend long hours exploring the city on foot or by bike. However, those sensitive to humidity may want to take precautions, such as staying hydrated and wearing breathable clothing.
Another factor influencing the weather is the wind. San Francisco can be quite windy, especially in areas near the coast and the bay. The wind can make the air feel cooler than it actually is, so it's advisable to bring a windbreaker or light jacket. The strong winds also contribute to the city's reputation as a great place for sailing and windsurfing. San Francisco weather in May is also shaped by these winds.
Preparing for Your Trip: What to Pack
Packing for San Francisco in May requires some consideration due to the variable weather conditions. Layers are key to staying comfortable throughout the day. Start with a base layer of lightweight, breathable clothing, such as cotton or merino wool. Add a mid-layer like a fleece jacket or sweater for warmth, and top it off with a waterproof and windproof outer layer. This will allow you to easily adjust to changing temperatures and weather conditions.
In addition to clothing, comfortable walking shoes are essential. San Francisco is a city best explored on foot, and you'll likely be doing a lot of walking, especially with its steep hills. Choose shoes that provide good support and traction to navigate the city's varied terrain.
Don't forget to pack sunscreen and sunglasses, even if it seems overcast. The sun can be surprisingly strong, especially when reflected off the water. A hat can also be useful for protecting your face from the sun and wind.
Other useful items to bring include a reusable water bottle to stay hydrated, a small backpack for carrying essentials, and a portable charger for your electronic devices. With a little preparation, you can ensure you're comfortable and ready to enjoy everything San Francisco has to offer in May.
