Peak Season:

Although it rains a lot in Seattle there is significantly less during the months from April to October. As the summer weather (June – mid September) is also mild, this half of the year is the most pleasant time to visit. The summer season is the most popular time and is when most people book flights to Seattle. Hotel rates and airfare tickets tend to be more expensive from around mid-May to mid-September.

Travellers can experience long days as during June and July it stays light until 10pm. You may still need to pack an umbrella as there are occasional summer showers, although, you’ll find plenty to keep you occupied indoors, such as, going to see something in the theatres and performance halls. Summer is also when the big, primarily outdoor, festivals are held.

Off Season:

The rainy season goes from October to April, which is when fewer people tend to visit the city, compared with the drier peak season. This is a good time to look for flights to Seattle and accommodation, as you may be able to find a good deal.

If you visit during October, why not attend the annual Fremont Oktoberfest? This event features the biggest beer garden in the Northwest with over 100 mircobrews and craft beers on offer to taste and enjoy. There is also a variety of attractions for all the family, such as, the Oktoberfest 5k beer run, live Seattle Bands and a children’s activity area.

The most pleasant weather during the off-season occurs in early May and late September. So why not book during these months to make the most of cheap flights to Seattle.
