Napa in July
Good time to visit
July is peak summer with hot, dry weather and maximum crowds. Great for pool days and evening events, but plan around the heat for daytime activities.
Weather
July brings the year's hottest weather to Napa Valley. Expect daily highs in the upper 80s to low 90s Fahrenheit with bone-dry conditions and minimal humidity around 35%. Mornings start pleasantly cool but afternoons can feel quite warm, especially in the valley floor areas.

All Months
April through June brings perfect weather and blooming mustard flowers between the vines. September through November means harvest season — expect crowds but also the most exciting energy as grapes come in. Summer gets hot and expensive, with July temperatures hitting 90°F and hotel rates peaking. But those long evenings on restaurant patios make up for the heat. Winter sees rain and some winery closures, though February's mild days offer the best deals and smallest crowds. Harvest typically runs late August through October, with Pinot Noir coming in first followed by Cabernet Sauvignon. Book accommodations early for harvest season — many properties require three-night minimums and charge premium rates.
