Best time to Visit Pacific Northwest

Spring arrives gradually across the Pacific Northwest, bringing milder temperatures, longer days and the first signs of new growth. Portland and Seattle begin to blossom, while the mountains can remain snow-covered well into May.

Why visit now:

• Spring blooms – cherry blossoms and fresh greenery bring spectacular colour to region’s major cities
• Fewer crowds – a quieter time to explore Portland, Seattle and scenic natural areas
• Fresh landscapes – snow-capped mountains contrast beautifully with emerging spring buds
• Active wildlife – spring brings increasing opportunities to spot birds, marine life and other wildlife

Good to know:

• Cooler and wetter conditions are still possible
• Temperatures vary – coastal areas are generally milder, while inland and high-altitude areas can be considerably cooler
• Some higher-elevation areas/routes may remain inaccessible

Summer is one of the most popular times to visit the Pacific Northwest, bringing warmer temperatures, long daylight hours and drier weather. Cities such as Seattle and Portland come alive, while the region’s mountains, forests and coastline are at their best for exploring.

Why visit now:

• Warmest, driest and most reliable period for outdoor exploration
• Long daylight hours – to make the most of outdoor activities
• Best access to national parks and mountain areas
• Ideal coastal weather – perfect for visiting the region’s beaches and lakes

Good to know:

• Peak season – popular national parks and attractions can be busy, particularly in July and August
• Book ahead – accommodation, car hire and park services can be in high demand
• Mountain weather can change quickly – even in summer, higher elevations can be cooler and conditions can shift

Autumn brings cooler temperatures, changing colours and a quieter feel to the Pacific Northwest. September can still offer warm, settled days, while October brings crisp morning, spectacular foliage and changeable weather across the region.

Why visit now:

• Autumn colours – forests and mountain landscapes take on rich shades of red, orange and gold
• Fewer crowds – a more peaceful time to explore cities, scenic routes and national parks
• Milder conditions – September can offer some of the region’s best weather for outdoor exploring

Good to know:

• Changeable weather – rain increases as autumn progresses so come prepared
• Shorter days – daylight hours decrease through September and October so plan longer scenic drives accordingly
• Early snow – mountain routes and trails at higher elevation can become less accessible later in the season

Winter brings cooler temperatures, shorter days and peaceful atmosphere to the Pacific Northwest. Seattle and Portland remain accessible year-round, while the mountains receive plenty of snow, creating excellent conditions for winter sports and dramatic scenery.

Why visit now:

• Cosy city breaks – cafés, restaurants, museums and galleries make Seattle and Portland worthwhile even on wetter days
• Ski season – mountain resorts like Mount Hood and Mount Rainier offer skiing, snowboarding and other winter activities
• Winter scenery – snow-capped mountains and misty forests create a striking backdrop
• Fewer visitors – a quiet time to explore the cities and coastal areas

Good to know:

• Rain is common – particularly in coastal areas, with November to March being the wetter months
• Snow at higher elevations – mountain roads and passes can be affected by winter conditions, and some routes may close
• Road conditions can vary – winter tyres or chains may be required, so check conditions before setting out
