Honestly, if you've lived in the Valley long enough, you know that a "sunny" forecast in January usually comes with a massive asterisk. Right now, Sacramento is sitting in that weird mid-winter pocket where the atmosphere can't quite decide if it wants to be a postcard or a swamp.
As of Friday night, we’re looking at a weather sacramento 5 day stretch that basically defines "seasonal transition." We just came off a surprisingly mild Friday with a high of 63°F, which felt great, but the humidity is currently pinned at 97%. That’s basically like walking through a damp sponge. If you’re heading out early Saturday morning, expect that thick, Tule fog to be hanging over the I-5 like it owns the place.
What’s Actually Happening This Week
The big story for the weekend isn’t a massive storm—it’s the cloud cover. Saturday, January 17, is looking mostly cloudy with a high of 60°F. There’s a 20% chance of rain during the day, so it’s not exactly a washout, but you’ll probably want to keep a light shell in the car just in case. The wind is almost non-existent, puffing at a measly 2 mph from the north.

By Sunday, things dry out a bit. We’re hitting 62°F with partly sunny skies. It’s the kind of day where you can actually get some yard work done without shivering, though the overnight low of 40°F means your heater is still going to be earning its keep.
- Monday, Jan 19: Expect more of the same. High of 61°F, low of 39°F. Mostly "meh" skies—partly sunny and quiet.
- Tuesday, Jan 20: The sun finally makes a real appearance. We’re looking at a high of 59°F and clear, sunny conditions. It’s technically cooler, but it’ll feel better because the dampness is finally backing off.
The Humidity Factor Nobody Mentions
Everyone looks at the temperature, but in Sacramento, the humidity is the real vibe-killer in January. We are seeing levels stay between 75% and 81% for the next several days. When it’s 46°F outside (our current nighttime temp) and the humidity is that high, the cold doesn't just sit on you—it gets into your bones.

It’s a far cry from the atmospheric river drama we saw earlier this month. Remember those road closures on Kiefer Boulevard and the water rescues near Jackson Road back on the 4th? We’re past that. The Sacramento River at the I Street Bridge is currently sitting at 25.1 feet, well below the 33.5-foot flood stage. We’re in the "recovery and recharge" phase of the month.
Why This Forecast Matters for Your Week
The UV index is staying at a 2, which is basically the lowest it goes. You aren't going to burn, but you aren't getting much Vitamin D either. If you're planning a trip up to Tahoe, keep in mind that while we're just getting "mostly cloudy" vibes down here, the Sierra is still dealing with the tail end of some clipper systems.

Kinda interesting note: the state is officially out of drought conditions as of this week. Governor Newsom’s office just put out a report on the 15th highlighting that our reservoirs are in great shape. So, while a weather sacramento 5 day forecast featuring "mostly cloudy" skies might feel a bit gloomy, it's actually part of a very healthy water year for us.
Survival Tips for the Next 5 Days
- Check your wipers: That 20% rain chance on Saturday is just enough to smear road grime across your windshield if your blades are shot.
- Layer up: We’re seeing a 20-degree swing between the afternoon highs and the overnight lows. 60°F feels like t-shirt weather to some locals, but 40°F is definitely "break out the heavy coat" territory.
- Watch the fog: With humidity this high and winds this low, Monday morning commutes are likely to be a "pea soup" situation.
If you’re waiting for the real heat or a massive downpour, you’re out of luck this week. We’re stuck in the middle. It's grey, it's cool, and it's quintessentially Sacramento in January.
Next Steps:
If you have outdoor plans for Saturday, keep an eye on the local radar around 10:00 AM. That 20% precipitation chance is most likely to manifest as a light, annoying drizzle rather than a real storm. For Sunday and Monday, you’re clear for outdoor activities, just make sure you’ve got a sweater handy by 4:30 PM when the sun starts to dip.
