Corona Heights Park Weather
Park • San Francisco Bay Area
Corona Heights Park is a steep, rocky knob of red Franciscan chert rising to about 520 feet between the Castro and Buena Vista Park. San Francisco Recreation and Parks manages its roughly 13 acres. The Randall Museum, a playground, and an off-leash dog area sit on the lower slopes. An old quarry amphitheater lies below the bare summit outcrop known as the corona. It is smaller and lower than Twin Peaks, but sits close enough to downtown that its summit has some of the city's best views.

The hourly fog, wind, cloud, and temperature patterns on this site are the same for all of them. Real differences between them come from hills, elevation, and wind exposure that the model cannot resolve.

What shapes Corona Heights Park's weather
From the summit of Corona Heights you can often watch the line between foggy and sunny San Francisco. Fog spills over Twin Peaks and around Sutro Tower to the southwest, while downtown, off to the east, keeps its sun. Because it is lower than Twin Peaks, the hill is less often buried in the marine layer, the cool, moist ocean air that forms the fog. On deep fog days it disappears too.
The bare chert summit has almost no shelter. The afternoon sea breeze crosses it with full force, and thin, rocky soil means the hilltop dries quickly after rain. The steep trails erode easily, because runoff funnels straight down them in heavy rain.
Tips for visiting Corona Heights Park
Bring a windbreaker for the summit
The afternoon sea breeze crosses the bare summit with almost no shelter, even on sunny days.
Park at the Randall Museum
The museum has parking, and there is limited parking at the 15th Street tennis courts. Muni buses stop nearby on Castro Street and Roosevelt Way.
Take care on the 15th Street descent
The 0.2-mile trail down to the tennis courts is the steepest section, with loose gravel. It is slipperiest after rain.
Enter at Roosevelt and Museum Way
Bill Kraus Meadow at the entrance leads to the off-leash dog area. The park is open from 5 a.m. until midnight.
Corona Heights Park through the seasons
- Spring (March–May)
- Wildflowers carpet the grassland, including checkerbloom, California poppy, Douglas iris, and Johnny jump-up, host plant of the callippe silverspot butterfly.
- Summer (June–August)
- Summer afternoons are windy on the exposed summit, with fog often visible over Twin Peaks to the west. Mornings and early evenings are calmer.
- Fall (September–October)
- Fall is typically the most pleasant season on the summit, with less fog and lighter wind late into the day.
- Winter (November–February)
- Winter rain runs straight down the steep, eroded trails and leaves them slick. Wait a day or two after a storm before climbing.
Activities and the weather that matters
- Summit viewpoint: Go on clear, calm mornings or fall evenings. On windy summer afternoons the bare summit is cold.
- Wildflower walks: Spring after a wet winter brings the best bloom. Avoid the steep dirt trails right after storms.
- Randall Museum visit: The museum on the park's lower slope is a good fallback when wind or rain makes the summit unpleasant.
