Seattle is famous for coffee, and there’s certainly evidence of the residents’ love for it – check out the “original Starbucks” (which has moved but still has its original vintage look) next to Pike Place Market as well as the abundance of independent coffee shops and roasters making their mark in the city. But there’s more to Seattle than coffee. Pike Place Market itself, with its fruit, fish, cheese and flower sellers, is a feast for the senses. And artistic creativity abounds. The iconic Space Needle has great 360-degree city views, while the Olympic Sculpture Park is nine acres of first-class sculpture. The harbour is great for a stroll and there’s the Seattle Aquarium and Seattle Great Wheel there too to check out. Do not miss out on seeing the beautiful Puget Sound. Hop on a cruise for whale watching or head out to Bainbridge Island for a day trip. Ferry boats, a convenient way to travel and experience Seattle’s natural beauty, connect the numerous islands and shores throughout the waterways of Elliott Bay. Stay on dry land and walk through Seattle’s dozens of parks and enjoy the sight of sailboats roaming through the bay. Go shopping in landmark districts or attend one of the many festivals held year round in Seattle. When you feel like taking a trip that combines both natural beauty and urban activities, you won’t be disappointed booking a flight to Seattle.

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.
