Decoding the Distinct Seasons of San Francisco

Unlike many other locations, San Francisco weather doesn't neatly fit into four distinct seasons. Instead, the city experiences a more subtle shift, largely influenced by its proximity to the Pacific Ocean and the surrounding topography. Understanding these seasonal variations is key to enjoying everything the city has to offer. Let's break down the typical weather patterns you can expect throughout the year.

Spring in San Francisco: The Fog Rolls In

Spring in San Francisco, typically from March to May, is often characterized by the arrival of Karl, the city's affectionately nicknamed fog. This marine layer rolls in from the Pacific, bringing with it cool temperatures and, at times, significant cloud cover. While the inland areas may bask in sunshine, the coastal neighborhoods, including the iconic Golden Gate Bridge, are often shrouded in a chilly mist. Temperatures during spring typically range from the low 50s to the high 60s Fahrenheit. Layering is essential during this time; a warm jacket, scarf, and hat are recommended, even on seemingly sunny days. The wind can also pick up, adding to the chill factor. Despite the fog, spring also brings beautiful blooms to the city's parks and gardens, making it a visually stunning time to visit, if you are prepared for the cooler temperatures and occasional drizzle. Remember, the San Francisco weather in spring is often the foggiest, especially in the mornings and evenings.

However, even on a sunny afternoon, the wind can make it feel cooler than the temperature indicates. Average temperatures range from the mid-50s to the low 70s Fahrenheit. Summer is generally drier than spring, but the fog can still bring moisture and reduced visibility.
