Pretty accurate as usual
They are pretty spot on for north of San Diego inland. It did rain A. LOT at the end of Feb into early March and then some mire in late March. We were all stuck inside anyway that’s to COVUD but the rain made it seem more dire. But I love the rain so bring it on! So far they are on target for summer and mid July does look to be a hot one. Hopefully they are right about Sept and Oct being cooler. I hate the Indian Summers out here.
yea, it's been cold
I also agree that Los Angeles has been far colder than it used to be. Some parts of L.A got snow for the first time in 50 years just last year in February 2019. Not to mention the bomb cyclone that came through in November and dropped nearly half a foot of snow in Lancaster and elevated parts of L.A. 2020 so far has just been fairly dry rather than hot, May and June did have some heatwaves but nothing like some summers have done. While global warming may be a threat it's definitely not this world ending catastrophe many alarmists make it out be. In fact Co2 doesn't even hold heat for that long. But either way winter 2020-2021 doesn't look like it's going to be much warmer. We will have to wait and see.
cold
I've lived in LA for over 30 years. I've noticed the temperature getting colder, not warmer. In fact, we've had record breaking long cold spells in the past decade. We're into July and I'm still waiting for summer to arrive. The almanac confirms we've been experiencing below average temperatures. I'm still waiting for global warming to happen. We could use a little of it now.
Santa Monica Weather
I dont see much of a difference in Santa Monica living here for over 35 years and in California for 40 years. Generally the 80s were hotter, 90s cooler, 2000s back and forth and still we have some hotter summers and some cooler ones, sometimes more rain and cooler winters and sometimes, warmer less rainy winters. We have had drought periods over the past 40 years too, but nothing like centuries ago when there were droughts over 50-100 years long. Seems like the young people think that Santa Ana winds are a new phenomena, there are not and actually they are less common that past few years. I'm not sure global warming is as profound as the young people think it is, but they havent been around and dont know, they are just exposed to constant alarmist warnings.
Not accurate
Forecast is off by a lot, may has been much warmer than usual and it barely rained in February
Geoengineering
Caucasians can't stand the heat so they blew up the kitchen. Chemtrails are wrong.
Geo-engineering
I don't think the weather people can speak honestly about geo-engineering because they have to sign non-disclosure agreements.
Weather comment
I'd like to know where all these comments come from, saying it's hot! Not! I am in the "high desert" of SoCal, and right now it is 50 degrees on 3-15. We had at least 7 inches of Snow on Thanksgiving! First time! And the day after Christmas was additional snow. I am a native of Pennsylvania and I do not like snow! Not after all the snow I shoveled most of my life in PA. It's 1:42 PM here and my heater just came on. I want some heat! Bring it. Very tired of cold here. And with "CoronaVirus Panic", nothing seems right anymore, hardly. Another comment about clouds in the 1980's, who can remember that? They look the same to me. As far as the Almanac getting the weather forecast right, they do it better than any other source I know! Keep it up guys!
Warm weather
Although I am a native southern Californian, I am no fan of warm weather. That said, it is not something new & has nothing to do with jets’ vapor trails. We always have a heat spell in mid to late February. My husband & I always look for it somewhere around Washington’s Birthday (Feb. 22) because when we were dating in the early ‘80s we went to the park on said birthday/holiday in shorts & I wore a sleeveless top. I think weather memory must be much like color memory in that it seems to be fairly inaccurate in many.
Farmers almanac ain’t what it used to be
Farmers almanac ain’t what it used to be. You’re right Andy it’s those white lines in the sky they are spraying chemicals... it absorbs the moisture in the air, causes a high pressure system, and the aluminum lands on the ground making fires spark more easily. It’s called “Geoengineering”.
There are side effects to this… It causes other parts of the country to have severe opposite weather, like flooding etc.
humans are controlling the weather now, and have been for about 40 years.
Have you noticed the clouds in the sky do not look the same as they did when we were kids in the 1960s
