Climate Overview: What Makes Camas, WA Weather Unique
Camas sits in western Washington at a low elevation near the Columbia River, which moderates temperatures compared with higher Cascade foothill towns. The city has a warm-summer Mediterranean climate, often classified as Csb, with wet winters and relatively dry summers. Most rain arrives between October and March, while July and August can go weeks with little or no measurable precipitation.
The Pacific Ocean drives the region’s weather, sending moist systems inland during the cool months. The Cascade Range creates a rain-shadow effect that helps dry out summers east of the Portland metro area. At the same time, the Columbia River Gorge acts like a natural wind tunnel, pulling cool or cold air through the region and creating localized gusts, fog, and occasional ice.
Seasonal Temperature Trends
Spring in Camas usually starts cool and damp, with highs in the 50s and 60s and lows in the 40s. By May, afternoons often reach the mid-60s to low 70s, though mornings stay crisp. Summer brings the warmest conditions, with average highs in the upper 70s to mid-80s and lows in the 50s. Heat waves can push temperatures into the 90s or, occasionally, near 100 degrees.
Fall transitions gradually, with September highs often in the 70s before dropping into the 60s and 50s by November. Winter highs typically range from the mid-40s to low 50s, while overnight lows settle in the mid-30s to low 40s. Cold snaps can send temperatures into the 20s or teens, and those events are when snow, ice, and frozen roads become more likely.
Precipitation, Cloud Cover, and Wind
Annual precipitation in Camas averages roughly 42 to 48 inches, with the wettest months falling between November and January. Rain often arrives as steady, light-to-moderate showers rather than intense thunderstorms. Cloud cover is common from fall through spring, and stretches of gray, drizzly days can last for a week or more.
Wind is another key part of Camas, WA weather. During winter, east winds can push through the Columbia River Gorge, bringing colder air, gusty conditions, and sometimes freezing rain or ice. In summer, lighter west winds and river breezes help moderate afternoon heat. Fog can form along the Columbia River and in low-lying areas, especially during fall and winter mornings.
Month-by-Month Weather and Local Impacts in Camas
January and February are usually the coolest and wettest months, with highs in the 40s and lows in the 30s. Snow is possible but often melts quickly at lower elevations, while higher parts of town may see a little more accumulation. March and April bring milder days, more showers, and the first real signs of spring growth.
May and June warm up nicely, with May highs near 65 to 70 degrees and June highs in the low 70s. July and August are the driest and sunniest months, ideal for outdoor plans but also a time to watch for heat and wildfire smoke. September remains pleasant, October turns wetter and cooler, and November and December bring back the rainy, cloudy pattern that defines the holiday season.
Winter Weather and Travel Considerations
Winter weather in Camas is rarely extreme by national standards, but it can still create hazardous conditions. Snowfall totals are usually modest, yet even a few inches can snarl traffic on Highway 14, local hills, and the bridges into Portland. Ice is often the bigger concern, especially when Gorge winds bring freezing rain or when overnight temperatures drop below freezing after a rainy day.
If you commute during winter, check forecasts from the National Weather Service, WSDOT, and local traffic sources before heading out. Keep an emergency kit with blankets, water, a flashlight, and snacks in your car. Allow extra time on bridges and overpasses, which freeze first, and use caution on shaded roads and neighborhood streets that may stay icy longer than main arterials.
Summer Weather and Outdoor Recreation
Summer is when Camas shines for outdoor recreation. Lacamas Lake, Round Lake, the Washougal River, and the region’s many trails are popular from June through September. Mornings are usually cool and comfortable, making them great for hiking, running, or paddling. Afternoons can get warm, so plan heavier activities before noon or after the peak heat.
Heat safety matters during late July and August, when temperatures can climb into the 90s. Drink plenty of water, wear sun protection, and never leave children or pets in parked cars. Wildfire smoke from the Cascades or eastern Washington can also drift into the area, reducing air quality. On those days, check the Air Quality Index and consider indoor workouts or shorter outings.
Keeping an eye on the local forecast is the simplest way to make the most of Camas weather, whether you are commuting through winter rain, planning a summer lake day, or just deciding whether to carry an umbrella. Conditions can vary from downtown to Prune Hill and along the Columbia River, so a quick check before you leave can save you from unexpected rain, wind, or heat. With a little preparation, you can enjoy everything this corner of Washington offers in every season.
