April in the PNW: Rain, Sun, and Everything In Between—What to Expect

The Pacific Northwest in April is a rollercoaster of weather, blending lingering winter chills with the first whispers of spring warmth. Whether you're planning hikes, garden prep, or just want to avoid getting caught in a downpour, here’s what you need to know.

Typical April Weather Patterns

April marks a transition period in the PNW, where the region shifts from relentless rain toward milder, sunnier days. However, unpredictability reigns—expect everything from sudden showers to surprise sunshine.

• Rainfall: Showers are frequent, but less intense than winter months. Coastal areas see more precipitation than inland valleys.
• Temperature Swings: Daytime highs range from mid-50s to low 60s (°F), while nights can still dip into the 40s.
• Mountain Snow: Higher elevations may still get late-season snow, affecting passes like Snoqualmie and Santiam.

Microclimates Make a Difference

The PNW isn’t uniform—microclimates mean your experience varies drastically based on location:

1. Coastal Zones (e.g., Astoria, Cannon Beach): Cooler, foggier, and windier with frequent drizzle.
2. Willamette Valley & Puget Sound: More sunshine breaks between rain, especially toward month’s end.
3. Eastern Washington/Oregon: Warmer and drier, with desert regions seeing early spring blooms.

Outdoor Activities: Timing is Key

Want to make the most of April? Plan around these trends:

• Best Hiking: Late April, when trails dry out. Try Columbia River Gorge or lower-elevation forest hikes.
• Gardening: Start cold-hardy plants early, but hold off on tomatoes until May.
• Wildlife Watching: Bird migrations peak—visit Ridgefield National Wildlife Refuge or the Oregon Coast.

The "April Fake-out" Phenomenon

Locals know: a sunny week in early April often tricks newcomers into packing away jackets—only for a chilly storm to return. Always keep layers handy!

What Do You Think?

• Is April the best or worst month in the PNW? Why?
• Do you think climate change is making April weather more unpredictable?
• Should cities invest more in rain-prepared infrastructure, or is it part of the PNW’s charm?
• Are "sun breaks" worth the hype, or just a desperate excuse for optimism?
