What to Expect: Temperature, Fog, and Sunshine

Average Temperatures

In July, San Francisco's average high temperature hovers around 65°F (18°C), while the average low is around 53°F (12°C). These temperatures are mild, but it’s important to note that they can fluctuate. Some days may be warmer, reaching into the 70s, while others can remain cool, especially when the fog is heavy. The consistent cool temperatures are due to a combination of the cold Pacific current and the city's unique geography.

The Infamous Fog

One of the most defining characteristics of San Francisco weather, especially in July, is the fog. Often affectionately referred to as “Karl the Fog,” this dense fog rolls in from the Pacific Ocean, particularly in the mornings and evenings. The fog is most prevalent along the coast and can extend inland, blanketing iconic landmarks like the Golden Gate Bridge. While the fog can create a picturesque scene, it also plays a significant role in keeping temperatures mild. It's not uncommon for the fog to clear by midday, revealing sunny skies, only to return again in the late afternoon. — Roosevelt Avenue: Jackson Heights Guide

Sunshine and Clear Skies

Despite the fog, July in San Francisco does offer plenty of sunshine. The fog tends to burn off during the day, providing clear skies and pleasant conditions for outdoor activities. The city experiences an average of 10-12 hours of sunshine per day in July, making it a great time for sightseeing, walking, and exploring. However, it’s always wise to be prepared for the fog to return, as it can change weather conditions quickly.

Rainfall

Rainfall in San Francisco during July is minimal. The city experiences a dry season during the summer months, with very little precipitation. On average, July sees less than 0.1 inches of rainfall, making it one of the driest months of the year. This lack of rain contributes to the sunny days and clear skies that are common during this time.

Microclimates

San Francisco is known for its microclimates, meaning that the weather can vary significantly from one neighborhood to another. Areas closer to the ocean, like the Sunset District and Outer Richmond, tend to be cooler and foggier, while inland areas, such as the Mission District and Potrero Hill, are often warmer and sunnier. This is due to the city's unique topography and the way it interacts with the ocean breeze and fog. When planning your day, it’s a good idea to consider these microclimates and be prepared for different conditions depending on your location.

How to Prepare for San Francisco Weather in July

Layering is Key

The best way to prepare for San Francisco weather in July is to dress in layers. Start with a base layer, such as a t-shirt or tank top, and add a sweater or fleece jacket. A light outer layer, like a windbreaker or light jacket, is also a good idea, especially for foggy days or evenings. This layering approach allows you to adjust your clothing throughout the day as the temperature changes.

Pack for All Conditions

Even though July is a dry month, it’s wise to pack for a variety of conditions. Include items like jeans, long-sleeved shirts, and closed-toe shoes. A scarf or hat can also be useful for keeping warm on foggy days or evenings. Don't forget sunglasses and sunscreen for sunny days, and a reusable water bottle to stay hydrated.

Check the Forecast

Before heading out for the day, it’s always a good idea to check the local weather forecast. This will give you a better sense of what to expect and allow you to adjust your clothing and plans accordingly. There are many reliable weather apps and websites that provide detailed forecasts for San Francisco, including hourly updates and long-range predictions.

Be Fog-Aware

When planning outdoor activities, be aware of the fog and how it might impact your plans. Fog can reduce visibility, especially in areas near the coast, so it’s important to exercise caution when driving or walking. If you’re planning to visit a landmark like the Golden Gate Bridge, be prepared for the possibility that it may be shrouded in fog. However, don't let the fog deter you – it can create a unique and atmospheric experience.

Examples & Use Cases

Golden Gate Bridge Visit

Imagine you're planning a visit to the Golden Gate Bridge in July. You wake up to a foggy morning and decide to dress in layers, wearing a t-shirt, a fleece jacket, and a windbreaker. As you approach the bridge, the fog is thick, and the temperature is cool. You're glad you brought your layers! However, by midday, the fog starts to dissipate, and the sun emerges. You remove your jacket and enjoy the clear views of the bridge and the city. This scenario illustrates the importance of layering clothing and being prepared for changing conditions.

Exploring Golden Gate Park

Another example is planning a day in Golden Gate Park. The park is vast, and the weather can vary within its boundaries. The western side of the park, closer to the ocean, tends to be foggier and cooler than the eastern side. If you’re planning a picnic, you might choose a spot on the eastern side to take advantage of the sunshine. Regardless of where you are in the park, it’s a good idea to have layers on hand, as the weather can change quickly.

City Sightseeing

When exploring different neighborhoods in San Francisco, you might experience the city’s microclimates firsthand. For instance, you might start your day in the foggy Sunset District and then head to the warmer and sunnier Mission District. Dressing in layers will allow you to adapt to these different conditions and stay comfortable throughout your day of sightseeing.
