Jack London Square Weather
Town • San Francisco Bay Area
At the foot of Broadway, where downtown Oakland meets the estuary, Jack London Square has been a landmark since the mid-1800s. The Port of Oakland calls it the city's only publicly accessible mixed-use waterfront and marina area, with restaurants, estuary walking paths, and Sunday farmers markets. The island of Alameda lies across the water. The square is the Oakland stop for the San Francisco Bay Ferry and for a free water shuttle to Alameda Landing.

What shapes Jack London Square's weather
The cool estuary water keeps Jack London Square's temperatures in a narrow range. On summer mornings, low cloud that has crossed the bay can hang over the waterfront a little longer than over downtown. Evenings by the water turn chilly fast once the sun drops. In return, the square rarely gets as hot as inland Oakland. The exception is a rare day when dry wind blows offshore, from the hills toward the bay, and stops the cooling sea breeze.
Low ground on a tidal channel means the waterfront also feels winter's highest tides. King tides, the highest tides of the year, come around the turn of the year. They can push water high along both shores of the estuary even on dry days.
Tips for visiting Jack London Square
Arrive by ferry
The Oakland and Alameda ferry route links the Oakland terminal at the square with Main Street Alameda and the Downtown San Francisco Ferry Terminal. A crossing takes about 15 to 25 minutes.
Cross to Alameda free by water shuttle
The Oakland-Alameda Water Shuttle runs from the foot of Broadway to Alameda Landing with no fare.
Come Sunday for the farmers market
The Port of Oakland lists Sunday farmers markets among the square's regular events.
Pick a sheltered table after 3 p.m.
On summer afternoons the west wind comes straight up the estuary. Indoor seating or the lee side of a building is warmer than the open promenade.
Bring a jacket for evening
Even on warm days, the waterfront cools quickly after sunset.
Jack London Square through the seasons
- Spring (March–May)
- Spring skies are clearer than winter's, and the afternoon wind on the estuary strengthens into May.
- Summer (June–August)
- Summer brings breezy, mild afternoons and cool evenings on the water. Morning low cloud is common and can linger by the waterfront.
- Fall (September–October)
- September is as warm as August, and the sea breeze eases through October. Fall is a good time for outdoor dining on the promenade.
- Winter (November–February)
- Winter is the rainy season. The City of Alameda, across the estuary, warns that king tides around Thanksgiving, Christmas, and January can cause coastal flooding even without rain.
Activities and the weather that matters
- Waterfront dining: Outdoor tables are best on calm fall afternoons and warm evenings. Summer wind off the estuary makes outdoor tables chilly by late afternoon.
- Walking the estuary paths: The paths are good in most dry weather, and in summer the morning is calmer than the afternoon.
- Boating on the estuary: The city's boating programs run on Lake Merritt and the Oakland Estuary. Calm mornings suit paddling better than windy afternoons.
- Ferry ride across the bay: Clear fall and winter days after a storm give the best views of San Francisco. Summer crossings are windy and cool on deck.
