Long Beach WA weather is defined by a classic Pacific Northwest maritime climate, marked by mild summers, wet winters, and heavy annual rainfall totaling around 75 to 81 inches. If you're planning a trip or considering a move to this Washington coastal stretch, understanding the rhythm of ocean breezes, persistent winter storms, and sudden microclimate shifts is essential.
Unlike inland regions that experience extreme temperature swings, the Pacific Ocean acts as a thermal blanket here. Summer daily highs typically hover in the mid-to-upper 60s°F, while winter lows rarely drop far below freezing. However, navigating the local atmosphere requires more than looking at a basic temperature chart; you need to prepare for sudden coastal fog, high wind speeds, and concentrated seasonal precipitation.
Spring Transitions and Coastal Fog
Spring along the Long Beach Peninsula brings a slow, deliberate transition from cold winter storms to stable weather. March and April keep things brisk, with daytime highs ranging from 53°F to 56°F. You'll see frequent morning marine layers and coastal fog banks rolling in off the Pacific.
As May approaches, conditions improve noticeably. Rain totals drop significantly compared to winter months, and afternoon sunshine breaks through the cloud cover more often. For travelers, spring is a quiet time to explore the Washington State Parks beach trails without summer crowds, provided you pack layers and a dependable windbreaker.

Common Spring Packing Mistakes
Many visitors assume spring on the West Coast means mild sunshine. Packing only light sweaters leaves you shivering when a stiff ocean breeze picks up off 50°F water. Always bring a waterproof shell and wool layers.
Summer Sunshine and Mild Temperatures
Summer is the peak season for outdoor activities, running roughly from late June through early September. July and August are the driest and clearest months of the year, averaging under 1.5 inches of rain per month. Daytime highs average a comfortable 66°F to 69°F, while nights drop down to the low 50s°F.
Humidity stays low, and oppressive heatwaves are rare, though occasional inland weather patterns can push temperatures higher for a day or two. Because the National Weather Service forecasts regular sea breezes, you won't need air conditioning, but you will need sunglasses and sunscreen due to glare off the sand.
Fall Storms and Dramatic Skies
September often carries over the pleasant warmth of late summer, but October marks a sharp turning point. Rainfall climbs rapidly, jumping from roughly 2.5 inches in September to nearly 7 inches in October.
By November, the region enters its heavy precipitation cycle, regularly recording over 10 inches of rain for the month. This is prime season for storm watching. Powerful low-pressure systems move in from the Pacific, bringing sustained winds and dramatic crashing waves along the shoreline.
Winter Wind and Heavy Precipitation
Winters are cool, wet, and windy. December and January average high temperatures around 48°F to 50°F, with overnight lows dipping near 36°F to 38°F. Snow is rare on the immediate beach due to ocean heat moderation, but heavy downpours and wind gusts exceeding 30 to 40 mph are common during passing winter gales.
During severe storm events, local authorities monitor coastal flooding risks along low-lying roads. Checking real-time updates via the Pacific County Emergency Management Department helps residents and visitors stay safe during high-surf advisories.
Understanding Local Microclimates
The geography of the Long Beach Peninsula creates distinct microclimates. The western oceanfront is fully exposed to raw marine winds and heavy salt spray. In contrast, properties situated closer to Willapa Bay or tucked behind primary dune ridges experience slightly calmer air.
Even a short drive inland across the peninsula can reveal temperature differences. A foggy, drizzly morning right on the beach might give way to brighter, clearer skies just a few miles away.
Frequently Asked Questions
Does it ever snow in Long Beach WA?

How much rain does Long Beach get annually?
The area receives between 75 and 81 inches of precipitation per year, with the vast majority falling between October and March.
