Emeryville Weather

April is consistently Emeryville's strongest weather month. The data backs this up: April 2025 averaged highs of 72.4F with a comfort score of 90 out of 100, nearly 13 hours of sunshine per day, and almost no rain. It sits in that sweet spot where winter storms have passed and summer fog has not fully settled in. June through August are also excellent, with highs in the mid-to-upper 70s and comfort scores ranging from 84 to 89. Those summer months do bring slightly more morning fog, but it typically burns off by mid-morning. If you want warm, dry, and bright, April is hard to beat. May is a close second, with zero recorded rainfall in May 2025 and nearly 13 hours of daily sun. The fall months, particularly October and November, bring considerably more rain and drop comfort scores into the low-to-mid 70s. Plan accordingly.

Emeryville stays genuinely mild through summer, which is one of its most underappreciated qualities. The hottest months are July and August, when average highs land around 76 to 78F. That is warm enough to be comfortable outdoors, but not the scorching heat you would find in inland cities like Concord or Livermore, which can top 95F on the same day. Emeryville sits right on the bay, which keeps temperatures regulated by marine air flowing in off the water. The bay breeze becomes a real presence by afternoon, especially in July and August. You rarely see temperatures above 85F here, and heat waves that hammer the inland valleys tend to arrive as pleasant warm days in Emeryville. If anything, the challenge in summer is the morning fog, which can linger for a couple of hours. By noon, though, you are typically looking at clear skies and ideal temperatures. It is a forgiving summer climate.

Emeryville winters are mild by almost any standard. Average lows in December and January hover around 42 to 46F, and daytime highs stay in the high 50s to low 60s. You are not dealing with freezing temperatures or frost. That said, the combination of cool air, occasional wind off the bay, and overcast skies makes it feel chillier than the thermometer suggests. January 2025 had a comfort score of only 73 out of 100, largely due to 6.58 inches of rainfall and limited sunshine averaging around 6.4 hours per day. November and December tend to be the roughest stretch, with November 2025 recording just 6.3 hours of sunshine and over 5 inches of rain. The Bay Area's rainy season runs roughly November through March, with January being historically the wettest month. A light jacket and layer-friendly clothing will handle most winter days here without drama.

Yes, but Emeryville's fog pattern is more moderate than what you would experience in San Francisco or the coastal neighborhoods. The 18-month data shows an average of 2.2 hours of morning fog per day, which is notable but far from overwhelming. Summer months like June and July tend to see the most fog, with June 2025 recording 3.6 hours of morning fog on average. The marine layer forms along the coast and pushes inland overnight and into the morning hours, and Emeryville, sitting right at the bay's edge, is in its path. The good news is that the fog typically lifts by late morning, leaving the afternoon clear. September often sees the clearest mornings of any month, with fog averaging just 1.3 hours per day in September 2024. If you want to maximize sunshine, plan outdoor activities for late morning through late afternoon.

For most of the year, yes. Emeryville racks up roughly 249 comfortable days per year, which makes outdoor dining a reliable option from April through October. The summer months are particularly pleasant: highs in the mid-70s, low humidity, and afternoon sunshine after the morning fog clears. The bay breeze is real, though. On summer afternoons, wind picks up enough that a light layer can make the difference between comfortable and chilly when you are sitting still at an outdoor table. Spring is arguably the ideal season for outdoor dining: April and May combine warm temperatures, long sunshine hours, and minimal wind compared to summer. Winter is more hit or miss. November through January brings rain, shorter days, and cool temperatures that make outdoor dining less appealing, though a dry December afternoon in Emeryville can still be quite nice. Check the forecast rather than assuming.

Wind is a genuine factor in Emeryville. The city sits right at the bay's edge at just 16 feet of elevation, with no significant terrain to block the afternoon sea breeze that channels through the Bay Area's gaps and across the water. Summer afternoons, especially July and August, tend to bring the most consistent wind. The Bay Area's wind patterns are driven by the pressure differential between the cool coast and the hot Central Valley, and that effect is strongest in summer. Mornings are typically calmer than afternoons. In winter, wind shifts to come more from rain-bearing storm systems, which creates a different, gustier feel on storm days. Day-to-day variation is significant, so checking a forecast before planning extended outdoor time is worth the habit. Nearby Temescal and Rockridge, a few miles inland, tend to be noticeably less windy on typical afternoons.

Emeryville sits between Oakland and Berkeley in both geography and climate, but its waterfront position gives it a distinct character. Being right on the bay means cooler summer temperatures than inland Oakland, more consistent afternoon wind, and slightly more morning fog exposure. Downtown Oakland is typically a few degrees warmer on summer afternoons because it is set back from the direct bay influence. Berkeley, directly to the north, shares a similar mild climate but with more elevation variation across its neighborhoods. Emeryville's flat, low elevation keeps temperatures remarkably stable. The Bay Area's famous microclimates mean that just a few miles of distance can produce noticeably different conditions, but Emeryville's weather is relatively predictable compared to hillier neighbors. Its average comfort score of 82 out of 100 across 18 months reflects a genuinely pleasant baseline that most Bay Area visitors and locals would find welcoming.

Emeryville's rainy season runs from November through March, with January being the peak. The 18-month data shows January 2025 as the wettest month with 6.58 inches of rain, followed by November 2024 with 6.01 inches. October and November mark the transition into wet season, when rainfall picks up sharply after essentially dry summers. May through September are reliably dry: May 2025 recorded zero rainfall, and June, July, and August combined averaged under half an inch for the whole season. Emeryville gets about 77 rainy days per year, which is consistent with the rest of the East Bay flatlands. Rain events here tend to come in waves tied to atmospheric river systems rather than steady drizzle, meaning you might see a week of heavy rain followed by a stretch of clear, dry days. December 2024, for example, had only 0.85 inches of rain despite being mid-winter, a reminder that even the wet season has its dry stretches.

Layers are the right call in Emeryville year-round, for different reasons depending on the season. In summer, mornings can feel cool and foggy, afternoons warm up into the mid-70s, and evening bay breezes push temperatures back down. A light jacket that you can tie around your waist covers all three phases of the day without weighing you down. Dressing in layers is genuinely the Bay Area approach, not just a cliche. In spring and fall, add a slightly warmer mid-layer because temperature swings are more pronounced. Winter visits call for a waterproof outer shell and warmer base layers, especially if you are spending time near the water. Comfortable walking shoes matter more than any specific weather gear since the waterfront paths and shopping areas involve a lot of pavement. Sunglasses are useful year-round: even in winter, afternoon sun off the bay can be surprisingly bright. Skip the heavy winter coat unless you are visiting during a storm system.

Emeryville averages 9.5 hours of sunshine per day across the year, with significant seasonal variation. The sunniest stretch runs from April through July, peaking at 12.8 hours in April 2025 and 12.9 hours in May 2025. Those long spring days, combined with relatively dry conditions, make them the most light-filled period. Summer months like June and July stay above 11 hours of sunshine even with morning fog factored in. October is where the drop becomes noticeable: sunshine falls to around 6.8 to 7.5 hours per day and keeps declining through November and December, which both average about 6.3 hours. Winter fog and overcast skies account for most of that reduction. The Bay Area's four-season pattern plays out clearly in Emeryville's sunshine data: a long dry season of reliable sun, followed by a shorter, cloudier wet season. With roughly 249 comfortable days per year, Emeryville is a genuinely good-weather city by regional standards.
