Honestly, if you're checking the fresno ca weather 10 day forecast right now, you're probably just trying to figure out if you need the heavy coat or if the "Valley tuxedo"—shorts and a hoodie—will suffice. It is January 16, 2026. Right now, the Central Valley is doing that weird thing it does where the sky looks like a damp wool blanket.
You've got a high of 58°F today and a low of 43°F. That sounds mild, right? But any local knows that 50°F in Fresno feels different when the humidity is sitting at 83%. It’s a "get in your bones" kind of cold.
What's actually happening over the next 10 days
We are entering a classic stagnant ridge pattern. Basically, the air is sitting still.
Tomorrow, Saturday, January 17, we're looking at a high of 60°F and a low of 42°F. It'll be mostly cloudy. Sunday pushes a tiny bit warmer to 61°F. If you’re planning a trip to Woodward Park or heading out to the Chaffee Zoo, Sunday and Monday are your best bets with highs staying consistent at 61°F.
Here is the quick breakdown of the numbers you actually need:

- Tuesday (Jan 20): This looks like the "heat wave" of the week. High of 63°F, low of 40°F. Mostly sunny.
- Wednesday (Jan 21): Clouds return. High 61°F, low 42°F.
- Thursday (Jan 22): Sunny again, high 60°F.
- Next Weekend (Jan 23-25): We’re cooling back down to the high 50s. Friday and Saturday will hit 58°F, and Sunday the 25th creeps back to 60°F.
The rain? It's basically a non-factor. We’re seeing a measly 5% to 10% chance of precipitation across the board. If you see a drop, consider yourself lucky.
The Tule Fog Factor
What the standard fresno ca weather 10 day forecast doesn't always scream at you is the Tule Fog. The National Weather Service in Hanford just issued a Dense Fog Advisory effective through 11:00 AM today. Visibilities along the Highway 99 corridor are dropping to 1,000 feet or less.
It’s dangerous. No, really.
When you have these "partly sunny" days with 1 mph or 3 mph winds (which is what the forecast shows for the next 72 hours), the air just doesn't move. That moisture from the recent December storms gets trapped under a warm layer of air. This temperature inversion creates that thick, pea-soup fog that can make a morning commute to Clovis feel like a scene from a horror movie.

Air Quality: The Elephant in the Room
We have to talk about the air. It's kinda gross right now.
Because the air is so still—we're seeing winds from the south and southeast at only 3 mph—all the wood smoke and car exhaust is just hanging out at lung level. The San Joaquin Valley Air District has the AQI for Fresno at 142 today. That is "Unhealthy for Sensitive Groups."
If you’ve got asthma or you're just sensitive to pollution, maybe skip the outdoor run until Tuesday when things clear up a bit. The PM2.5 levels are hitting 52 µg/m³. For context, that’s high enough that the "no-burn" orders are usually in full effect.
The Sierra Nevada Connection
Even though Fresno is dry, the mountains aren't faring too badly. The California Department of Water Resources reported on January 13 that the statewide snowpack is at 78% of normal. The Central Region (that’s us) is at 77%.

It's a bit of a "wait and see" game. We need those January and February storms to hit the "frozen reservoir" of the Sierras to keep the Valley green come July. But for the next 10 days? The mountains are looking mostly clear, mirroring our valley floor stability.
Survival Tips for the Next Week
- The Layer Rule: You’ll start the day at 43°F in thick fog and end it at 61°F in bright sun. Wear a base layer that doesn't make you sweat when the sun finally breaks through at noon.
- Headlights ON: If you’re driving anywhere before 10:00 AM, turn your actual headlights on. Daytime running lights don't turn on your tail lights, and that’s how people get rear-ended in the Tule Fog.
- Air Filters: If you haven't changed your HVAC filter since the summer, do it now. With the AQI hitting 142, you want your indoor air as clean as possible.
- Hydrate: High humidity (81% tonight) usually makes people forget to drink water because they don't feel "thirsty" like they do in the 110°F summer. Don't fall for it.
The fresno ca weather 10 day forecast shows a remarkably stable, albeit slightly murky, stretch of winter. No major storms, no freezing snaps—just classic, gray, stagnant Valley winter. Enjoy the 63°F peak on Tuesday; it’s about as good as January gets around here.
Your Next Steps:
- Monitor the National Weather Service Hanford morning briefings if you have a commute, as fog conditions can change in minutes.
- Check the Valley Air District website before planning any strenuous outdoor activities this week to ensure AQI levels haven't spiked into the "Unhealthy" (Red) category.
- Ensure your vehicle's defrost system and windshield wipers are in top shape for the high-moisture morning fog cycles.
