Pyramid Lake isn't just a pitstop on the I-5. For anyone who’s ever hauled a boat up the Tejon Pass or tried to cast a line for striped bass, you know this place is a bit of a mood. Honestly, it’s one of those spots where the weather doesn't just "happen"—it dictates whether you're having the best day ever or fighting for your life against a 25-mph gust.
People often conflate this Pyramid Lake with the giant one in Nevada. Big mistake. We’re talking about the Southern California reservoir tucked into the mountains between Santa Clarita and Gorman. Because of that high-elevation canyon vibe, Pyramid Lake CA weather plays by its own rules.
The Current State of Affairs: January 2026
If you’re looking at the lake right now, it’s actually looking pretty decent for mid-winter. As of January 18, 2026, the mercury is sitting at a crisp 61°F under mostly sunny skies.
It’s definitely "light jacket" weather.

The wind is coming out of the northwest at about 8 mph, which is basically a gentle kiss compared to what this canyon can usually do. But don't get too comfortable. The forecast for the next few days shows a bit of a shift. While Monday looks even better with a high of 66°F, things take a turn toward the end of the week. By Thursday and Friday, we're looking at a drop into the mid-50s with a 35% chance of rain.
Basically, if you’re planning a trip, Monday is your golden window.
Why the Wind Here is a Total Diva
You’ve gotta understand the "wind advisory" culture at Pyramid. Because the lake is effectively a giant funnel in the Grapevine, the wind picks up speed like it's trying to win a race. Even on a "calm" day, you’ll see gusts hitting 20 to 24 mph easily.

For boaters, this isn't just a nuisance. It's a safety thing.
The Department of Water Resources (DWR) has been known to shut down boat launches when the whitecaps get too aggressive. It’s kinda frustrating when you’ve driven two hours only to find the ramp closed, but when you see the way the water chops up in the "canyons" section of the lake, you’ll get it.
Quick Seasonal Breakdown
- Spring (March–May): This is the sweet spot. Highs climb from the low 60s into the mid-70s. Everything is green, and the trout are biting.
- Summer (June–August): It gets hot. Like, 90°F+ hot. The water temperature hits a peak around 81°F in August, making it perfect for wakeboarding, but the sun is brutal.
- Fall (September–November): My personal favorite. The crowds thin out, and the "sharpest cooling trend" happens in November. You'll go from an 80-degree day in October to a 50-degree day in November faster than you can find your hoodie.
- Winter (December–February): Expect highs in the 50s and lows that occasionally dip to freezing (32°F).
Fishing and the 53-Degree Factor
Anglers live and die by the water temp here. Right now, the water is hovering around 53°F.
According to recent fishing reports from local guides and data from the DWR, this means the fish are moving a bit slower. You're looking for cool-water species like trout and walleye. If you're hunting for those famous Pyramid Lake striped bass, you’ve gotta go deep.
They aren't hanging out on the surface in January.

Interestingly, the lake is currently open for full recreation as of early 2026, which is a relief. We had some messy storms earlier in the month that led to temporary debris closures, but the "Fair" rating of the Pyramid Dam by the Division of Safety of Dams means things are stable for now.
What You Actually Need to Pack
Don't be that person who shows up in a tank top and flip-flops in January just because it's sunny in LA.
- Layers are non-negotiable. The temperature can swing 20 degrees the second a cloud covers the sun.
- Sunscreen (even now). The UV index today is a 2, but at 2,569 feet of elevation, the sun still bites.
- Windbreaker. Even a light breeze across the water feels 10 degrees colder than it actually is.
Honestly, the best advice for Pyramid Lake CA weather is to check the "wind gusts" specifically, not just the "average wind." An average of 8 mph is fine; a gust of 25 mph will flip a light kayak or make docking a nightmare.
If you’re heading out this week, aim for Monday, January 19. It’s the warmest day of the week and the last bit of "true" sun before the clouds move in for the weekend. Keep an eye on the Los Alamos Campground status if you're planning to stay overnight, as fire restrictions often linger well into the winter months depending on how dry the brush is.
Load the boat, check the Northwest winds, and get there early. The marina at Emigrant Landing fills up faster than you’d think, especially when the weather is this clear.
