If you’re a lover of wine and good food, then you probably know that Napa Valley is one of the best places in the world to wine taste.

But did you know that October is one of the best times to visit this famous wine region?

The weather is still mild (not too hot or cold), so you can enjoy the grape picking without getting overheated or chilled.

And as an added bonus, there are fewer tourists around than during peak season.

The question is, what should you wear?

Here’s what we recommend.

Is it cold in Napa in October?

The average high temperature for October is 75 degrees, but you can expect highs to be in the low 80s during the first half of the month and in the low 70s at the end. 

The average low temperature for October is 57 degrees, but you can expect lows to be near 60 degrees up until mid-month and in the mid 30s during late October.

In October, the weather is usually sunny and warm, with just enough rain to keep everything green and lush. 

It’s also a great time to visit wineries because many winemakers take their harvest off early so they can get their grapes off right after harvest (instead of waiting until later in November or even December).

Does it get cold in Napa at night?

The weather in Napa is great in October, even if it is a bit on the chilly side.

The average temperature during the day is 75-80 degrees Fahrenheit (26 degrees Celsius), while it drops to around 50 degrees Fahrenheit (10 degrees Celsius) at night.

It’s important to note that this temperature variation can be greater depending on where you are in the valley and what time of day it is. 

For example, if you’re staying in Yountville or St. Helena you’ll likely see temperatures in the 70s during the day, but when you get into Calistoga or Napa Valley proper at night, temperatures could drop into the 40s or 50s.

What do you wear in Napa in October?

October is a great month to visit Napa.

The weather can be unpredictable and you may get a few days of rain, but it’s amazing how quickly the sky clears up and the sun shines again.

  • A scarf. 

It’s windy, cold nights and warm days.

Napa is famous for its unpredictable weather and the best way to stay warm and dry is to layer up with a scarf, hat, and waterproof outerwear.

Even if you’re taking a day trip or staying in town, bring an extra layer with you just in case.

  • A soft sweater or cardigan. 

The evenings tend to be cool but not freezing so you can get away with these lighter layers.

  • Boots.

There are lots of vineyards and wineries that are on hills or in the woods so having comfortable footwear is important!

Is October a good time to go to Napa Valley?

October is a great time to visit Napa Valley.

The weather is still warm, the crowds are gone and the grapes are ripening.

You’ll find that restaurants and wineries are less crowded and you’ll be able to enjoy your experience more.

October is also a great month for visiting Napa/Sonoma because it’s one of the few times in the year when you can sleep under the stars without freezing. That’s right, camping in October is possible and it’s great fun!

The weather in October in Napa/Sonoma is usually sunny with some afternoon clouds and temperatures near 70°F (21°C). The mornings start out cool but by midday it warms up quickly into the 60s°F (15°C). 

The evenings are cool enough to make sleeping under the stars very comfortable, even if you’re not used to sleeping on a cot!

It’s also a good time to go wine tasting as many wineries have reduced hours or even closed their tasting rooms by this time of year. This means less crowds at wineries, especially on weekends when most people travel.

Is there a dress code for Napa Valley wineries?

Wineries in Napa Valley are very casual. There’s no dress code, so you can wear whatever is comfortable for you. 

However, if it’s hot outside in the daytime or you’ll be walking around outside, it’s best to wear lightweight clothing and shoes that don’t have heels or pointed toes.

Sandals are always acceptable, even if they’re not made of leather or suede.

What should I pack for Napa Valley?

Napa Valley is a beautiful place to visit, and you want to make sure that your trip is as comfortable as possible.

Here are some things you should pack for your Napa Valley vacation:

  • Sunscreen

Sunscreen is essential for any outdoor activity, especially if you plan on spending time outdoors. Make sure you bring plenty of sunscreen with an SPF of 30 or higher.

  • Hat

A hat will help protect your face from the sun and keep it cool during hot days in the valley. Plus, it will add a little style to your outfit!

  • Lightweight clothes 

The weather in Napa Valley can change quickly and unexpectedly, so bring along some lightweight clothes that are easy to pack.

You’ll want something that can easily layer over a long sleeve shirt or lightweight jacket if it gets cold out during the day or at night. 

You might also consider packing a light raincoat just in case rain hits while you’re there.

If you’re planning on doing any hiking or exploring nature trails throughout Napa Valley, then definitely bring along some hiking boots or shoes.

How do people dress for dinner in Napa?

Dining in Napa is a special experience. It’s not like dining in other cities. The atmosphere is more relaxed, the food is amazing and the wine is even better!

There are no hard and fast rules when it comes to dressing for dinner in Napa, but there are a few guidelines that will help you look your best and feel comfortable.

  • Women dress slacks with heels, flat sandals. A good rule of thumb is to avoid anything too tight or too short. Dresses are also acceptable but keep them simple and elegant.
  • Men can wear slacks, khakis or sport coats with dress pants. Jackets are optional but if you do wear one, keep it simple and elegant without a tie and also without an abundance of buttons or pockets that might look tacky.


October is a great time of the year to visit Napa Valley. Regardless of when you plan on visiting, you will want to dress accordingly with layers. Otherwise, the day can be warm and sunny one minute and foggy or even raining the next. And if that isn’t enough, it can also get windy too. But overall, October is an amazing time to visit Napa Valley.
