Seattle is casual all year round. It's always a good idea to carry both an umbrella and sunglasses. You never know.

Spring
The air is still brisk in the morning and evening, but getting warmer as we inch closer to summer. Layering is a good idea, with a light jacket or sweater in the evening. Temperatures range from mid-50°s in April to high 60°s in June.

Summer
Seattle's summers can't be beat, with a scant 1 - 2 inches of rainfall monthly all season, and bright sunny days on the water. Temperatures range from low-70°s to high 80°s, with the occasional 90° heat wave. Consider sunscreen and headwear to protect you from the sun.

Fall
Autumn temps begin to decline back into the 60°s and 50°s, ending up around the mid 40°s in December. Layered clothing is smart, and you'll be glad you packed that water resistant jacket.

Winter
Winters can be crisp, but compounded with often wet, breezy air, they can be downright frigid. Wear your layers, water resistant outerwear, and bring along gloves and a warm hat. You'll want your umbrella at close reach, too. Temperatures hover between high 30°s and low 50°s, with an average 3.5 to 6 inches of rain monthly.


GOING OUT ON THE TOWN?
There are few dress code requirements in the city, as Seattle is deserving of its reputation as a casual destination. You will notice the dress code flexibility even in high-culture centers such as the Seattle Symphony, the Pacific Northwest Ballet and the Seattle Opera.

Seattle Opera
The Seattle Opera is flexible when it comes to dress code requirements. You will see opera-goers wear anything from evening gowns to khakis. So go ahead and dress up for a special night out, or dress down for comfort.

Pacific Northwest Ballet
Many times you will see more formal attire during the Holiday performances and opening nights, but anything between business casual and formal is welcome year-round.

Seattle Symphony
The Seattle Symphony welcomes a variety of attire – from business casual to tuxedo or formal gown. Many attendees tend to dress more formal for gala events, but most of the time you'll see concertgoers in whatever makes them comfortable.
