California just had its hottest and driest March ever recorded.
It was warmer than any April on record since 1895.
Warmer than the average May. And as dry as a typical July.
A month that would have been virtually impossible in the pre-industrial climate.

Whew.
All signs are increasingly pointing to a significant, if not strong to very strong, El Niño event. I'll have more to say in coming weeks & months, but for now I'll just say that this is increasingly likely to become a major regional-to-global climate driver in 2026-2027.
ALT Time series plot depicting predicted Nino 3.4 region ocean temperature anomalies from the latest (Mar 2026) ECMWF ensemble. It depicts an extremely rapid rise in such temperatures, from modest negative anomalies to strong positive anomalies, by mid-summer 2026--indicative of a transition from weak-moderate La Nina conditions to moderate-strong El Nino conditions over just a few months.

Hello spring! Meteorological winter is over.
The season featured record warmth in the West and was the coldest in a decade or more in the East.
According to preliminary data, it was the second warmest winter on record for the contiguous United States as a whole.

Crazy that whole food is cheaper than Safeway. In addition, Safeway treats you like a prisoner in their stores. Will be amazing if there is Aldi in SF. – at San Francisco, CA

ALERTSF: A young mountain lion was spotted near Pacific/Octavia. If you see the mountain lion, slowly back away, do not run. Call Animal Care & Control at 415-554-9400 or 911 in a life safety emergency.
If you have a child with you - pick them up - and keep dogs on leash. If the mountain lion approaches - make yourself 'big' wave your arms, shout, throw something, and again, do not run.
