weather or not

The Editors's picture

If it were in our power, we would give everybody the weather they want—and need (ok, 80% of it). As you may know, 1) the borders of/shapes of the weather regions are based on the climatological movement of weather systems [in very simple terms, how the wind blows]; 2) we make forecasts well in advance (this winter’s last winter), and 3) there are factors beyond our control or foresight or change over the months since the forecasts are made [ocean temps and jet streams probably lead the list].

We appreciate that you have faith in or mere curiosity about our weather forecasts, whatever the weather. Thanks for taking the time to come to this page and share your thoughts.

News Flash for SoCal - you’re NOT the only area on the map!!

Yet again SoCal thinks they ARE the only region in California included in the Farmers Almanac weather guide for Pacific Southwest Region. You might just get crazy and look at the entire region included in the Pacific Southwest map before you toss out your criticism. Farmers is generally accurate within a week or so - close enough to plan your garden planting. I know this because it has been my weather guide in superior California (meaning far northern Sacramento Valley - you know it’s where you get your WATER!!) for many, many years. Cut these guys some slack and acknowledge that geographically SoCal is just a fraction of this very important farming region. You probably need to stick with the Weather Channel.

Psychological Reasons for SoCal Negative Comments

I think a lot of these comments aren't really from frustration with the Farmer's Almanac, but with global warming and what it's doing to Southern California. The fact is, we're concerned, deeply concerned, when we don't see rain in January and February, and by extension, an end to global warming in our lifetimes. It leaves one, who lives in California, with a feeling of doom. Wishing for it to get better does not solve the problem. Governments, including our federal one, have to start taking this "new normal," as officials are calling it more often, much more seriously, and so do we, the average citizens. It's no longer a liberal left issue; the reality is here.

your predictions are ridiculously wrong

There will be no rain in California through most of February, yet you predict a lot of rain. What is your excuse for being absolutely wrong on a regular basis?

accuracy

The Editors's picture

We do not calculate our accuracy until at least the end of a season (not weekly, not monthly). And this season (winter) is not over yet. Traditionally our predictions are 80 percent accurate; sometimes more, sometimes less. If the ocean temps, jet stream/s, oscillations, and other factors would conform to our expectations, we—and every other weather prognosticator—would be 100 percent accurate all the time.

Well...not ridiculously wrong...sheeesh

I think your comment must refer to the graft at the head of these comments,
which says that February will be near NORMAL - not less, not more.

Why I moved

I was born and raised in Long Beach. After 50 years, two years ago I moved to the Portland area, I will never move back to LA! The traffic, (I drove the 405/10 interchange everyday) the people suck now and everything is brown and dead. I remember Big Bear having three feet of snow in October, they don't even get three feet in a year now. When I was a kid it used to rain and hail, not anymore. It is so green and beautiful here in Portland. We've got more rain the in last two weeks than LA in the last year!

Southern Cali

California weather, especially SoCal, is being controlled by geo-engineering. It creates these incessant high pressure domes and steers the storms (rain) up further north of our state.

I completely agree with Connie's comments.

You hit the nail on the head, Connie. Here in San Diego we are going on a year and a month without decent rainfall. The climate mafia has sealed SoCal's fate. Just look up, we get sprayed here every day, especially when precipitation should be moving in. Just look around at all of the dead and dying vegetation. A direct result of aluminum, barium, etc. poisoning from above. No more trees or animals. Many think this region is paradise. Let me say that hell might also have sunshine and palm trees, but that does not make it a nice place.

Really?

“Stormiest periods in early and late January”? Right. It’s like 65 and sunny. No rain in sight. It’s not just a problem with forecasts in So Cal, I’m in Redwood City, 20 miles south of San Francisco and north of San Jose.
