I agree. The very first time there is any significant rain, green grass starts growing. It could be October (but not often), or it could be November or December, but unless it's such a bad year that it doesn't rain at all, and we did have a couple of those in recent memory, the hills are green by January.

But remember that SoCal has had a lot of drought years recently, and I'm speaking from a SoCal point of view.

The residential neighborhoods are green all year round thanks to evergreens and irrigation, though.

Yeah, that's my experience as well. Yes there can be anomalies where it's brown until Feb. There are also times when it greens up in October from an early season rain.

My nephew has a picture in front of the Hollywood sign in January of this year and the hills look green like Ireland. It was New Year's Day.

The winter rains last winter started early for SoCal, though. It really depends year to year, Feb 2018 on Google Street view in Irvine shows mostly brown hills.

I guess hills facing the ocean might green up earlier from the fog, but foothills in Inland Orange County green later.

SoCal weather is pretty complicated, one man's microclimate is not another man's microclimate. We all have different experiences as such.

I can agree with this. It slowly starts to get green (assuming a non drought year) in December but if you're talking about entire hillsides of pure green then that happens in March. That's what I mean by green, not just some green mixed in with the brown.

I lived in SoCal up until 2017, drought seems to be getting more common and winter rains keep coming later, although this winter it seemed like winter rains came very early for SoCal. The old timers in SoCal probably are right in that twenty plus years ago, the hills started greening earlier.

It's really not consistent, though. Looking at Irvine SR 73 during Feb 2018, you see most of the hills are brown. Same for Jan/Feb 2019. The fact is that rainfall in SoCal is not consistent year to year. Some years have tons of rain, some years are drought years, still other years have plenty of rain but December would be bone dry and the big storms would start in late January or February.

You got lots of rain early on in the season last winter in LA, that is not the case every year.

Also, hills facing the coast get greener earlier due to more fog, while those on the windward side don't green as early.

Then you have the fact that fires can char the landscape for a couple years in certain spots, diminishing from the greenery.

I am not saying that during every winter in California that the hills don't green up until February. I am simply saying that with California's highly variable wet seasons, you can't count on a January greening of the hills, not that it never happens.

I think sometimes you see me make a generalization, and then you think I am making an absolute statement. This happened last time with how I stated that Santa Ana winds usually blow in the fall and winter and are least likely in the summer. Instead of acknowledging that, you simply kept pointing out that Santa Ana winds blow in the summer. I never denied that, I simply said that Santa Ana winds blow infrequently during the summer, which is different from saying they never blow during the summer. And then you went silent.

Also, when I said that high dew points in California usually come with higher temps, you then said that that's not true, because there are many heat waves that come with dry heat. I never said that most heat waves in SoCal come with humid heat. I said most high dew points come with higher temps on SoCal, which is an entirely different proposition. So please read my posts carefully before making a straw man out of them and then ghosting me when I clarify my position.

We need climate change to help California like it did in 2017, 2018 & 2019. Something was changed and it was a good thing.

Not every area in California has 100 degree temperatures. Eureka and San Francisco are quite cool even in the summer.

As for fires, those who don't live in or near mountains or canyon areas are not living in a fire zone.

It's a La Nina year. It's normal to have a dry year during La Nina. All those affected by it can do, is muddle through it, and hope that when it's over, there will be more precipitation.

That's true. And last season, Los Angeles received above average rain, 19 inches (normal is 15 inches).
