Rain on the way after another dry month

Be prepared to get wet – and it’s about time. Sacramento is long overdue for a good, deep soaking.

According to the National Weather Service, Sacramento can expect 1.15 inches on Thursday, the first day of December. After a frosty Friday (with early-morning lows expected to hit 32 degrees), another inch of rain is predicted for this weekend.

That will get December’s rain totals off to a solid start. Historically, December in Sacramento averages 3.25 inches of precipitation.

But that average rainfall – if we do indeed see it – would almost match Sacramento’s total for all of 2022 so far. The first 11 months totaled only 3.60 inches of rain. That’s 25% of normal for that period.

October and November, the start of Sacramento’s rainy season and the new “water year,” historically average 2.62 inches. This season, Sacramento received no rain in October and 1.16 inches in November. Most of that moisture (0.81 inches) fell on Nov. 8, our last truly rainy day before this week’s storm system.

Our current water year total is 44% of normal; that’s better than 2022’s percentage so far but still a long way from average. If December doesn’t produce a deluge, 2022 looks like it will go down as the driest year in recorded Sacramento history.

So, yes, even with this week’s rain, we’re still in a drought. Sacramento averages 17.65 inches annually – 14 inches more than we’ve received so far this year – and it will take a very wet winter to make up for 2022’s moisture deficit.
