If you’ve spent any time living in or visiting the 98664 zip code, you know the drill. One minute you’re looking at a clear view of Mt. Hood from the Heights, and the next, a wall of gray mist is swallowing the Evergreen Highway. It’s classic Pacific Northwest. But weather Vancouver WA 98664 has some quirks that set it apart from the rest of Clark County, mostly because of how it hugs the Columbia River.
People always talk about Portland weather, but Vancouver isn't just "Portland North." There's a specific microclimate happening here. The 98664 area—covering the Father Blanchet Park, Northcrest, and Ellsworth neighborhoods—sits right in the crosshairs of the Columbia River Gorge’s atmospheric vent. That means when the wind kicks up, you feel it first. It’s not just a breeze; it’s a localized event that can make your backyard feel five degrees colder than someone living up in Salmon Creek.
The Gorge Effect and the 98664 Wind Chill
Let’s be real: the wind is the biggest player here. Because 98664 is positioned along the river corridor, it acts as a funnel. Cold air from Eastern Oregon and Washington gets trapped and then hurtles through the Gorge, hitting the eastern edge of Vancouver with some serious force.
I’ve seen days where the official forecast for Vancouver says 40 degrees, but if you’re walking your dog near Columbia River High School or down by the waterfront trails in the 98664 zone, it feels like 30. The "Gorge wind" is a legitimate local phenomenon. It’s why you see so many sturdy, old-growth evergreens in the older neighborhoods; they’ve spent decades hardening themselves against those east winds.
National Weather Service (NWS) data often shows that the PDX airport station—just across the water—records slightly different gusts than what actually hits the residential streets of Ellsworth. The friction of the land and the specific elevation changes in 98664 create turbulent pockets. It’s annoying for your heating bill, honestly.
Why the Rain Feels Different Here
It isn't just about the volume of water falling from the sky. It’s about the duration. In 98664, we get what locals call "the big mist." It’s that fine, pervasive drizzle that doesn't show up well on radar but soaks you to the bone in ten minutes.

Statistically, Vancouver gets about 42 inches of rain a year. That’s more than the national average, but less than places like Forks or even parts of Seattle. However, the 98664 area often sees more "gray days" because the moisture tends to hang low against the hills of the Heights. You’ll look south and see sunshine over the airport, while you’re stuck in a literal cloud. It’s a strange, localized isolation.
Snow, Ice, and the 98664 "Hill Factor"
Snow in Vancouver is usually a joke—until it isn't. Because the 98664 zip code features a lot of sloping terrain, particularly as you move from the river up toward Mill Plain, a little bit of ice goes a long way.
Remember the 2021 ice storm? While some parts of the county just had slush, the 98664 area was a skating rink. This happens because of "cold air damming." That freezing air from the Gorge stays low, hugging the riverbank, while warmer air moves in aloft. The result is freezing rain that coats everything in a quarter-inch of glass.
- The Commuter Trap: If you’re trying to get onto Highway 14 from Lieser Road or Ellsworth during a silver thaw, good luck.
- Tree Hazards: The silver maples and Douglas firs that make 98664 beautiful become liabilities when they’re carrying a thousand pounds of ice.
- Power Outages: Because many neighborhoods in this zip code are established with older infrastructure, the combination of wind and ice often leads to localized blackouts that your friends in the newer Camas developments might miss entirely.
Most people don't realize that a three-degree difference is the gap between a "work from home" day and a "stuck in the ditch" day. In 98664, we live on that margin more often than the rest of the metro area.
Summertime Heat Islands and River Breezes
Summer is where 98664 actually wins. While the concrete jungle of downtown Portland is baking in a 100-degree heatwave, the proximity to the Columbia River provides a natural cooling system for this zip code.

There’s a reason people love the Evergreen Highway area. The "river breeze" is a real thing. As the land heats up, it draws cooler air off the surface of the water. On a scorching July afternoon, the neighborhoods south of Mill Plain can be significantly more comfortable than the suburban sprawl of Orchards or Battle Ground.
However, we have to talk about the smoke. In recent years, late summer has brought wildfire smoke from the Cascades. Because 98664 is in that Gorge funnel, it often gets hit with the heaviest concentrations of particulates. The air quality index (AQI) can spike here faster than in other parts of the city because there’s nowhere for the air to go—it’s just pushed through the corridor.
Managing Your Home for 98664 Weather
If you're living here, you have to adapt. You can't just look at a generic weather app and think you’re prepared.
First, check your insulation on the east side of your house. That’s where the Gorge wind hits. If your windows are old, you’re basically throwing money out into the yard. Second, keep an eye on your drainage. The soil in many parts of 98664 is heavy with clay. When the winter rains settle in, the water doesn't always have a place to go, leading to "swamp backyards" by February.
What Most People Get Wrong About Vancouver Weather
The biggest misconception is that it rains all the time. It doesn't. It clouds all the time. From November to May, the sky is the color of a wet sidewalk. But the actual rainfall is often just a light sprinkle.

Another myth? That it's exactly like Portland. It isn't. The geography of the 98664 zip code—the way it rises from the riverbank up to the plateau—creates a specific "lift" in the atmosphere. This can cause localized showers that hit the Heights while downtown Vancouver stays dry.
Expert Tips for 98664 Residents
- Don't trust the "Rain" icon: Look at the "Probability of Precipitation" and the wind direction. If the wind is from the East, prepare for a chill. If it’s from the South/Southwest, expect the actual rain.
- The "Gorge Scrape": Keep a high-quality ice scraper in your car. Not a cheap $2 one. You will deal with ice more than snow in this specific zip code.
- Humidity Control: Because of the river proximity, the air is damp. Use a dehumidifier in your basement or lower levels during the winter to prevent that "PNW funk" from settling into your carpets.
Strategic Next Steps for Navigating 98664 Weather
If you want to stay ahead of the curve, stop relying on the generic "Vancouver" forecast.
Get a personal weather station (PWS). There are dozens of them in the 98664 area connected to networks like Weather Underground. Checking a station located on Lieser Road will give you a much more accurate picture of your actual backyard conditions than a reading from the airport across the river.
Audit your trees. Given the wind patterns in this zip code, have a certified arborist check any large limbs overhanging your roof. The Gorge winds are relentless, and "widow-makers" are a real risk in the more wooded parts of the neighborhood.
Seal the leaks. Focus on weather-stripping your doors and windows, specifically on the eastern and northern exposures. In 98664, the wind is your biggest enemy regarding energy efficiency. Small gaps can lead to massive heat loss when the Gorge is "blowing" in January.
Prepare for the smoke. Invest in a high-quality HEPA air purifier before August hits. When the smoke pulls through the Gorge, 98664 is often the first place to see air quality drop into the "unhealthy" range. Having your filters ready early saves you the stress of a sold-out Home Depot later.
