Napa in August
Good time to visit
August brings peak heat and peak crowds to Napa Valley. The weather can be challenging during midday, but early mornings and evenings are magical.
Weather
August continues July's hot, dry pattern with some of the year's highest temperatures. The heat can feel intense during midday hours, with virtually no rainfall and humidity levels dropping to 30%. But those warm days create perfect conditions for evening outdoor dining under the stars.

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.
