Weather

The forecast has cleared up! A Sunny and Hot day. A hot morning in Oregon means no morning clouds.

Personally I think the coast is chancy. If I were travelling, I'd head for Silverton on OR214 or Olallie Lake on OR-224 - Mt Hood National Forest and then past Ripplebrook will get you to about 2000-feet and dispersed camping is allowed - carry water, toiletpaper and no campfires

Good Luck!

Oregon Weather

I'm sure you've heard, it rains all the time in Oregon. That's true. However, it mostly rains from October to May.

August in Oregon is sunny every day. So far in 2017 we have been sunnier and warmer than normal. Despite the rain this week (Aug 13) the ground is very dry, and the chance for thunderstorms is low.

Willamette Valley - I5 Corridor - Salem, Albany, Silverton

Portland, Salem and Eugene are in a valley between the Cascade Mountain Range and the Coast Range. Valley weather is about 10 degrees warmer and much sunnier than Seattle.

Valley weather has three patterns for August.

Sunny- Sunny all day.
Morning Clouds- A low cloud layer burns off around noon.
Thunderstorms- Local thunderstorms in afternoon or evening.

For eclipse viewers, the danger is the morning cloud formation often called "marine layer". This is caused by cool marine air which blows in overnight. You can easily recognize it because the clouds are low and evenly colored. The air is still and the clouds do not move. The marine layer burns off long before it blows away.

The marine layer generally burns off from south-east (Eugene area) to north-west (Portland Area). Unfortunately, the Eclipse begins at 9:30 and as the Sun is covered it will lose its "burn off" energy.

If the marine layer is heavy, then Eclipse day will be a bust. In the forecasts look for "cool mornings", and "morning clouds" as a sign they expect marine clouds on Eclipse day. In generally if the morning temperature is above 70 degrees there are no clouds, and below 65 degrees there are clouds in the forecast.

One way to escape the marine layer is to go up! If you are near the mountains on either side, get up to the highest elevation you can find. The marine layer stays within 500 of the valley floor, so many of the foothills will get you above it.

Eastern Oregon

Madras, Bend and the Eastern side of the state is generally sunny every day in August. There are sometimes local thunderstorms, particularly in the afternoons, and particularly near the mountains. These are generally local and pass within an hour or two.

So far in 2017, the Eastern Oregon thunderstorm pattern has not yet formed.

If you worry about missing the Eclipse because of clouds, the Madras Oregon area is your best bet for dependable weather.

Oregon Coast - Highway 101 - Newport

On the coast, the Marine Fog can come in heavy and dark. On very hot days, it will burn off just inland of the coast, so sometimes you can travel just two miles inland (and up) to get above it.

The Ocean is cool every day. So there is no real pattern for what days are sunny, foggy, cloudy or bright.

Eclipse goers should be ready to experience a fogbound eclipse if they commit to the Oregon Coast.
