Tiburon Weather

April stands out as Tiburon's ideal month, with temperatures around 72 degrees, 12.8 hours of daily sunshine, and minimal fog. July is another excellent choice, hitting 77 degrees with nearly 12 hours of sun. Both months offer that perfect blend of warmth and visibility that makes this waterfront town shine. If you're flexible, May and September are strong alternatives, offering similarly pleasant conditions without the slight summer fog uptick that happens in June. The best days cluster around these warm-weather months, with April and July consistently delivering those crystal-clear views of San Francisco Bay.

Tiburon's morning fog averages 2.2 hours daily, but it peaks in autumn and early winter. November and October see the heaviest fog, with fog lingering 3.8 to 4.2 hours into mornings, significantly reducing visibility and shortening usable daylight. This marine layer hugs the water here more persistently than inland Bay Area spots due to Tiburon's waterfront location and exposure to the Pacific. Spring through early summer sees minimal fog, especially April when it barely reaches 24 minutes. To understand how this fog forms, check out the article on morning fog in the Bay Area for the broader meteorology.

Tiburon rarely gets uncomfortably cold for outdoor dining. Winter lows average around 46 degrees, which is chilly but manageable with a jacket. April through September are your sweet spots, when evenings stay in the 52-57 degree range. Late spring and summer, particularly April and July, give you those warm afternoons around 72-77 degrees perfect for al fresco meals without worrying about bundling up. Even winter months stay above freezing. The real culprit isn't cold but fog, which rolls in heaviest October through early winter, blocking those coveted views from the waterfront restaurants. Layer up, and you'll be comfortable for outdoor dining year-round.

Tiburon and Sausalito experience similar Bay Area coastal conditions, but Tiburon sits slightly more exposed to the marine layer due to its peninsula geography. Both towns see comparable temperatures and fog patterns, but Tiburon's waterfront orientation means it catches more consistent marine air flow. Wind tends to be similar between the two, though Sausalito slightly shelters from certain northwesterly patterns. The real difference comes down to topography: Tiburon's lower elevation (just 16 feet) means it's more vulnerable to marine layer persistence, while Sausalito has more terrain variation. Both are excellent choices, but if you're fog-averse, check the specific forecast before deciding.

Tiburon averages 71 rainy days annually, with rain heavily concentrated October through March. November is the wettest month at 6.4 inches, followed by January at 6.5 inches. From April through September, rain becomes virtually nonexistent, giving you a reliable six-month dry season. Summer is especially dry, with July and August receiving less than half an inch monthly. This means you can confidently plan outdoor activities from late spring through early fall without worrying about rain. Winter and fall require more caution. For deeper context on seasonal patterns, the article on Bay Area rainy months explains why this concentrated winter rainfall happens along the coast.

Summer (June-August) demands a light jacket even on warm 75-degree days due to sudden fog and marine breezes, plus sunscreen for 10-12 hours of daily sunshine. Spring (April-May) calls for layers as temperatures swing from 52-degree mornings to 72-degree afternoons. Winter (December-February) requires a substantial jacket, as lows dip to mid-40s with frequent rain and fog. Fall (September-November) is tricky: bring layers and a rain jacket, especially in October and November when afternoon temperatures drop to the 50s-60s and rain becomes likely. Year-round, wind-resistant outerwear is smart given Tiburon's water exposure. The guide to dressing in layers for San Francisco weather covers this perfectly, as Tiburon shares many coastal layering challenges.

Tiburon averages 9.4 hours of daily sunshine annually, which is solid but not exceptional by Bay Area standards. The real story is seasonal variation. Spring peaks at 12.8-12.9 hours (April-May), making it gloriously sunny. Summer dips slightly to 10-11.7 hours as marine fog increases, particularly in June. Fall and winter plummet to 6-7.2 hours as overcast skies dominate. So while Tiburon isn't a sunshine outlier, your odds are excellent if you visit April through May. These months deliver both warmth and extended daylight, making them perfect for maximizing outdoor time with those panoramic Bay views.

Tiburon's waterfront location exposes it to consistent bay breezes, though it's not exceptionally windy compared to the ridges and headlands nearby. The Marin Headlands and other elevated areas catch more dramatic wind, while Tiburon's lower elevation and town setting buffer some gusts. Wind tends to build through afternoon hours and peaks in spring and fall when pressure systems become more active. Summer brings gentler breezes, while winter can see stronger gusts during storm passages. For understanding why the Bay Area gets so much wind, the article on Bay Area wind patterns explains the mechanics that affect Tiburon specifically.

November, December, and January form Tiburon's meteorological weak spot. November starts poorly at 64 degrees with 6.1 hours of sun and 6.4 inches of rain. December dips to 57 degrees during the day, adding fog persistence. January continues the pattern with 59-degree highs but slightly more rain at 6.5 inches. These months deliver low comfort scores in the 64-72 range, thanks to the combination of cooler temps, reduced sunshine, and persistent wet weather. If you visit during this period, embrace indoor dining and waterfront walks during brief midday clearings. February begins recovery as sunshine increases and temperatures edge up slightly, but the winter stretch remains Tiburon's least pleasant season.

Tiburon enjoys a remarkably mild climate with minimal seasonal extremes. Summer highs reach only 77 degrees (July), while winter lows bottom out around 44-46 degrees. That's a 30-degree difference, which sounds modest but matters less than the lack of true extremes. You'll never experience scorching heat or freezing cold here. Even in August, temperatures rarely exceed 76 degrees. This moderation is thanks to the marine influence that keeps the bay temperate year-round. Compare this to inland Bay spots that swing 40+ degrees between seasons, and you see why waterfront Tiburon is consistently comfortable. You can visit any month without weather anxiety, though comfort scores peak April through July when days warm into the low to mid-70s.
