Napa is a perfect tourist destination thanks to its world-class wines, breathtaking landscapes, Michelin-starred restaurants, opulent lodgings, rejuvenating spas, arts and culture, exclusive shopping, and well, we could go on and on.

Napa Valley truly provides something for everyone.

Tourists are attracted to the area by a variety of factors, including the excellent weather.

The Northern California wine area of Napa benefits from a mild, Mediterranean climate with lots of sunny days throughout the year, making it a great place to visit at any time of year in addition to being good for producing grapes.

The ideal months to visit Napa are frequently regarded as September and November.


The weather is nice, there are fewer people around, and hotel rates and other pricing are lower than they would be during peak season.

The ideal weather can be found in Napa Valley in September.

The daytime temperature is warm yet pleasant, while the evening temperature drops. Most days this month don’t get too hot or too cold.

The Taste of Mount Veeder, the Carnivus Maximus at Crocker & Star, and the Harvest Part at Inglenook are among the Napa events happening in September 2022.

At wineries all around the valley, you can participate in a variety of other enjoyable activities.

What To Wear For Daytime Activities In Napa?

While a half-day trip to Napa would be nice, we advise planning a full-day excursion to allow for all the fun activities, like wine tasting, dining out, and of course, touring.

We have enlisted a few fun activities to do during the daytime in Napa:

  • Labor Day Weekend
  • Live Music at the Blue Note
  • Hot Air Balloon Ride
  • Wine Train Tour
  • Cave Tours
  • JaM Cellars
  • Louis M. Martini
  • Domaine Carneros
  • Rutherford Hill Winery
  • Trefethen Family Vineyards
  • John Anthony Vineyards

You’ll want to be cool and comfortable due to the warm afternoon temps so two to three short-sleeved shirts should be brought along.

Additionally, if you intend to spend time outside at the wineries, they are ideal.

Pack a few pairs of jeans and casual pants.

The mornings and nights are chilly, despite the fact that it gets warm during the day.

There are a few colder days each month even though the average high is in the lower 80s.

Additionally, if the weather hasn’t warmed up yet when you start tasting in the morning, it is simpler to bring a light jacket along.

Make sure to bring a few pairs of relaxed shoes. You can buy stylish flat-soled footwear that will satisfy your feet.

You will spend a lot of time standing up because most wine tasting venues have little to no sitting.

Sunglasses are a must-have! In September, the majority of the days are sunny, so while you’re outside, you should wear sunscreen.

Shorts or skirts are also acceptable. Particularly if you go earlier in the month, we advise bringing one or two.

This is when the daytime temperature is still pretty warm.

What To Wear For Nighttime Activities In Napa?   

Napa is renowned for its charming downtown with its historic architecture. The town also boasts a promenade along the river that is lined with eateries and stores.

In Napa, there are many activities to do at night after a fun day. Here are a few recommendations:

  • Enjoy a show at the Uptown Theater
  • Taste exquisite wines at JaM Cellars
  • Explore the Oxbow Public Market
  • Treat yourself to the spa experience at Napa Valley Massage & Wellness Spa
  • Catch cabaret shows at Lucky Penny Community Arts Center
  • Blue Note Napa
  • Visit Crush Lounge
  • Go to the Grape Escape

Strike a balance if you’re a woman who worries about dressing too formally or too casually! Blue jeans and wedges might look chic and put together with a blouse. Country chic can be achieved with a dress, jean jacket, and cowboy boots.

For males, button-down shirts and golf clothing are always safe bets. Although wearing a bit more effort will guarantee that you blend in wherever you go, fashionable, dark wash jeans are also acceptable.
