Introduction

Planning a trip to San Francisco in May? Understanding the typical weather patterns can help you pack appropriately and make the most of your visit. May marks a transition period, moving away from the wetter winter months towards the warmer summer season. However, San Francisco's microclimates and unique geography create weather conditions that can be unpredictable. This guide provides a comprehensive overview of what to expect, ensuring you're prepared for anything Mother Nature throws your way.

What to Expect: Temperature, Fog, and Rain

San Francisco's weather in May is characterized by moderate temperatures, frequent fog, and the possibility of light rain. Here’s a breakdown:

• Temperature: Average daytime temperatures range from the low to mid-60s Fahrenheit (15-20 degrees Celsius). Evenings can be cooler, dropping to the high 40s or low 50s (8-12 degrees Celsius).
• Fog: San Francisco is famous for its fog, often nicknamed "Karl." May is a month where fog is very common, particularly in the mornings. The fog tends to roll in from the Pacific Ocean, blanketing areas near the coast, including the Golden Gate Bridge. It often burns off by midday, giving way to sunshine.
• Rain: While May is considerably drier than the winter months (December to February), occasional rainfall is still possible. The average rainfall in May is around 0.7 inches, so while you shouldn't expect constant rain, it's wise to be prepared.

Why This Matters: Understanding these weather patterns is crucial for planning activities and packing appropriately. Dressing in layers is key, allowing you to adjust to changing conditions throughout the day. Being prepared for fog is essential if you plan to visit coastal areas or iconic landmarks like the Golden Gate Bridge.

Potential Risks: While San Francisco's May weather is generally pleasant, there are a few potential downsides:

• Unexpected Cold: The fog can make temperatures feel much cooler than the average, especially in the mornings and evenings.
