Weather in Bend Oregon

Neither map gives a forecast for our area. We are right between the Pacific Northwest and the Intermountain Regions and neither has an accurate forecast for our area. We are located at the Eastern edge of the Cascades and the beginning of the high desert. It is kind of exasperating, trying to figure our forecast.....

Wheathr

The almanac is more accurate than our daily weather forecast on the weather stations. I love the almanac

Lol way wrong

It said this middle weak of October would be cool and periods of rain. Not even close. No rain in weeks and it’s been in the high 70s and sunny with bad air quality this whole middle October in Portland. Seattle and nor nor cal also way warmer and drier than average temps. Geez. Might as well say it’ll snow in July.

Week of Oct 22nd

Almanac was pretty accurate for Eastern WA. We’ve had rain all week.

Washington always rains of course

But the global warming is moving north every year and soon you in Washington will be like California

Just stop

Stop with the "global warming" fearmongering. Our planet has been cooling for over 2 decades now. NASA just told us that we are entering into a solar minimum that will be the closest thing to an ice age since the actual ice age, even calling for the nations of the world to burn MORE greehouse gasses in an effort to hyperheat the thermosphere. If you are going to push stuff like this, at least be somewhat knowledgeable about it.

One can’t preoct to the day

One can’t preoct to the day but being only 1 week off??? Not bad. Wish we had a torential snow storm this winter

Better than

Farmer almanac, while it isn’t always perfect it is fairly accurate. More so than Al Gore.

I too asked a question about inaccurate predictions. But never got a reply.
