What September is like in Napa Valley

September is peak harvest, the most exciting month in the valley. Highs are near 84F (29C), nights are cool and the air smells of crushed grapes. Crews work the vineyards, trucks roll to the wineries and tasting rooms are full. It is also the most crowded and expensive time of the year, and wildfire season can still bring smoke.

September suits wine lovers who want to see the crush in action and do not mind paying for it. Book hotels, tastings and dinners well ahead. Families may find it busy and adult-focused. If you want lower prices with pretty scenery, April or November are better.

What is especially good about Napa Valley this month.

01

The crush

02

Harvest-season dining

Restaurants in Yountville and Napa are at their best with the season's produce.

03

What to pack for September

  • Layers for warm afternoons and cool nights
  • Sun protection
  • Closed-toe shoes for vineyard and cellar tours

Beat the crowds

  • Visit midweek. Weekend traffic on Highway 29 and weekend tasting room crowds are far heavier, and rates drop Sunday through Thursday.
  • Use the Silverado Trail instead of Highway 29 to move up and down the valley with less traffic.
  • Choose spring or November over peak harvest for easier reservations and lower rates.
  • Book your most-wanted winery first, then build the day around it; morning slots are calmer and your palate is fresher.

Know before you go

  • Most Napa wineries now operate by appointment only. Walk-ins are limited, especially on weekends and during harvest.
  • Wildfire season, typically late summer into fall, has disrupted the valley in several recent years with smoke, road closures, and power shutoffs. Check conditions before you go.
  • The valley is open year-round. Winter brings quieter tasting rooms, and a few smaller wineries reduce hours.
  • Some wineries close on major holidays like Thanksgiving, Christmas, and New Year's Day.
