What to Wear in Napa in August

You will find that most places in Napa are laid back and casual. Most are fine with casual outfits including shorts, skirts, and sandals. If an event or winery requires more formal wear, they will often let you know before you arrive.

I often wear short sleeved shirts with shorts or jeans during the day. You will be standing most of the day, so make sure to wear something comfortable.

For shoes, I usually wear sandals or flat shoes. This makes it more comfortable during the tastings.

Usually in the mornings, when it is still a little cooler, I will bring along a light jacket. This way, I can taste wines outside if the option is available. I then remove the light jacket or sweater as the day heats up.

The dress code is the same for men. You can wear shorts or jeans along with sandals. You will see a variety of shirts from nicer business casual shirts to T-shirts. Both are fine as long as they are clean and are in good condition.

Although it is casual, make sure to stay away from torn or ripped clothing. Napa is an upscale destination and you might feel uncomfortable in clothing that is too casual.

5 Things to Do in Napa in August

1. Wine Tasting: The best thing to do this time of year is go wine tasting. There are more than 400 wineries in this small region each with a good selection of wines. Here are some of my favorite places to go tasting.

2. Nightlife: Head over to the Blue Note in downtown Napa for some great live music. The venue is in the Napa Valley Opera House and is a perfect place to catch a live show.

3. Hot Air Balloon Tour: Another fun way to experience Napa in August is on a sunrise Hot Air Balloon Tour. These tours start first thing in the morning with a 45-minute ride above the vineyards as the sun rises. Some also offer sparkling wine and brunch after the ride. Learn more about these tours.
