Honestly, looking at the sky in the Conejo Valley right now, you’d hardly believe it’s mid-January. While the rest of the country is probably digging out of snow banks or dealing with that biting East Coast slush, Thousand Oaks is basically showing off. If you’ve lived here long enough, you know the drill, but for anyone checking the Thousand Oaks weather 10 day forecast to plan a hike at Wildwood or just a grocery run to the Oaks Mall, the numbers are looking a bit wild for winter.
We’re currently sitting at a crisp 75°F today, Tuesday, January 13, 2026. That’s not a typo. It’s sunny, the humidity is a bone-dry 22%, and there’s a light northeast wind at about 8 mph. It feels more like a polished May afternoon than the dead of winter. But don't let the afternoon sun fool you; the microclimates in this valley are famous for a reason. You can be sweating in the sun at noon and reaching for a heavy Patagonia puffer by 6 PM.

The real story behind this heat spike is the wind. We’ve got northeast winds hitting around 12 mph today and tomorrow, which is a classic setup for those offshore flows that compress the air and send temperatures soaring. It’s why we’re hitting a high of 76°F today and potentially 78°F tomorrow.

Most people get wrong that "winter" in Thousand Oaks means rain. Historically, yes, January is supposed to be one of our wettest months, averaging about 3 to 4 inches of rain. But look at the next week. The chance of precipitation is sitting at a flat 0% for almost the entire stretch. It’s dry. It’s dusty. It’s beautiful, sure, but it’s definitely not the "wet winter" the local reservoirs are hoping for.
Breaking Down the Week Ahead
If you’re planning your life, here’s how the vibe shifts. Wednesday and Thursday (January 14-15) are going to be the peak of this mini-heatwave. We are looking at highs of 78°F both days.
- Wednesday: High of 78°F, Low of 62°F. Perfectly clear.
- Thursday: High of 78°F, Low of 60°F. Still sunny, but the humidity starts to creep up just a tiny bit.
- Friday: High of 74°F. A slight dip. You’ll notice some periodic clouds moving in at night as the low hits 59°F.
The weekend actually looks pretty decent for outdoor plans. Saturday, January 17, brings a bit of "partly sunny" action with a high of 76°F. Interestingly, there's a tiny 5% blip for rain that day, but don't hold your breath. It’s mostly just a psychological cloud cover. Sunday jumps back up to 78°F.
Basically, you’re looking at a solid block of mid-to-high 70s until we hit Monday, January 19. That’s when things start to normalize—or at least, move toward what passes for "cool" around here.
Why the Temperatures Drop So Fast
One thing you've gotta watch out for in the Thousand Oaks weather 10 day forecast is the overnight swing. Because we’re in a valley surrounded by the Santa Monica Mountains and the Simi Hills, the heat escapes the second the sun goes down.

On Wednesday, for example, you’re looking at a 16-degree drop once the sun sets. By next Wednesday, January 21, the daytime high drops to 70°F, but the overnight low plummets to 51°F. That’s the real Thousand Oaks experience: shorts at lunch, fireplace at dinner.
Humidity and UV Index Realities
Even though it’s January, the UV index is hovering around 3. It’s not "burn in ten minutes" territory like August, but if you’re out on the trails for three hours, you’re going to feel it.
The humidity is also worth mentioning. It’s staying low—mostly in the 20% range—until late next week. This is great for hair frizz but terrible for your skin and the local fire risk. When the humidity is this low and the winds are coming from the northeast, everything gets brittle. By Thursday, January 22, the humidity finally climbs back up to 51% as a more traditional marine influence tries to fight its way back inland, bringing a high of only 65°F.
What to Do With This Forecast
The 10-day outlook is basically a green light for every outdoor activity you’ve been putting off.
- Hydrate more than usual. With 22% humidity, you’re losing moisture faster than you realize.
- Layer like a pro. Don't leave the house in just a t-shirt if you’re going to be out past 5:00 PM.
- Check your irrigation. Since we’ve got 0% rain for the foreseeable future, your garden is going to think it’s summertime.
The trend for the end of the month suggests we might finally see some cooling. By January 22, we’re looking at a much more seasonally appropriate 65°F. Until then, enjoy the "winter" sun. It’s exactly why people pay the "sunshine tax" to live in the 805. Just keep an eye on those northeast winds; they're the real architects of the current forecast.
Actionable Insight: Plan your heavy outdoor workouts for Friday or next Tuesday when the temperatures are in the low 70s. Avoid the 78°F peaks on Wednesday and Sunday if you’re sensitive to the heat, as the direct sun in the valley often feels much hotter than the recorded air temperature.
