If you’re checking the forecast for weather in Point Loma CA and seeing a string of 72-degree icons, you’re only getting half the story. Honestly, it’s a bit of a local joke. You look at your phone, see "Sunny," and then walk outside into a wall of gray mist that feels like a damp wool blanket.
Point Loma isn't just a neighborhood; it's a six-mile finger of land poking straight into the Pacific. That geography changes everything. While someone in El Cajon is cranking their AC because it’s 95 degrees, you might be reaching for a hoodie at the Cabrillo National Monument. It’s weird. It’s beautiful. And if you don't understand the marine layer, it'll ruin your Saturday beach plans.
The Microclimate Nobody Tells You About
Most people think "San Diego" means one thing: constant sunshine. But the weather in Point Loma CA is governed by the Great Stabilizer—the Pacific Ocean. Because the peninsula is surrounded by water on three sides, it acts like a giant heat sink.
In the winter, the ocean stays around 58 or 60 degrees. This keeps the air from getting truly freezing. You’ll rarely see it dip below 45 degrees at night. But in the summer? That same ocean stays cool, rarely topping 70. When that cold water meets the warm inland air, it creates an inversion layer.

This isn't just "fog." It’s the "Marine Layer."
It’s a thick, low-lying cloud bank that can sit 1,000 feet deep. On a typical June morning, Point Loma is essentially inside a cloud. You can literally watch the sun "burn it off" from East to West. First, the inland valleys clear up. Then the bay side of Point Loma (places like La Playa) gets some sun. Finally, the ocean side at Sunset Cliffs might—might—see blue sky by 2:00 PM. Sometimes it never clears at all.
May Gray and June Gloom are Real
If you’re planning a wedding or a big outdoor event, listen up. Avoid May and June. Seriously.
Locals call it "May Gray" and "June Gloom," but it often spills into "No Sky July" and "Fogust." During these months, the high-pressure systems over the desert suck that cold, moist sea air inland. Because Point Loma is the first point of contact, it gets hit the hardest.
- Temperature Reality: It might say 68°F on the news.
- The "Feel" Factor: With 85% humidity and no sun, that 68 feels like 60.
- The Wind: There’s almost always a breeze coming off the water, especially at the tip of the peninsula near the lighthouse.
I’ve seen tourists show up in shorts and tank tops in June, shivering as they look for whales. Don’t be that person. Pack a light jacket. Even in the middle of summer, Point Loma is a "layers" kind of place.
Seasonal Shifts: When is it Actually Nice?
The best weather in Point Loma CA happens in the "Local's Summer." This is that magical window from September through October.
Why? Because the inland heat waves finally get strong enough to push the marine layer back out to sea. This is when you get those crisp, crystal-clear views where you can see all the way to the Coronado Islands and down into Mexico.
The Fall Heat Spike
September is often our hottest month. While the rest of the country is thinking about pumpkin spice and sweaters, we’re finally hitting 80 degrees at the beach. This is also when the Santa Ana winds kick in. These are hot, dry winds that blow from the desert toward the ocean. They reverse the natural flow. Suddenly, the humidity drops to 10%, the air feels like a hairdryer, and the sunset turns a deep, bruised purple because of the dust in the air.

Winter: The Rainy Season (Sorta)
We don't get much rain—maybe 10 inches a year if we're lucky. But when it does rain, it usually comes in bunches between December and March.
A winter storm in Point Loma is a spectacle. The waves at Sunset Cliffs can reach 10 to 15 feet. The wind howls across the ridge. But the second the storm passes? The air is the cleanest it will be all year. The visibility becomes insane. If you want the "perfect" photo of the San Diego skyline from the hills of Point Loma, go the morning after a winter rainstorm.
Survival Tips for the Point Loma Climate
You’ve got to play the "Bay vs. Ocean" game. The weather can change significantly depending on which side of the hill you’re on.
- The Bay Side (Eastern Slope): If you’re in Liberty Station or Roseville-Fleetridge, you’re shielded from the direct wind. It’s usually 3-5 degrees warmer here. The sun usually breaks through the clouds about an hour earlier than it does at the cliffs.
- The Ocean Side (Western Slope): This is the front line. Sunset Cliffs and the College (PLNU) get the brunt of the salt spray and the wind. If there’s a fog bank, you’re in it.
Basically, if you’re sensitive to the cold, stay on the bay side. If you want that rugged, wild coastal feel, the ocean side is your spot. Just realize that salt air is brutal on everything. Cars, patio furniture, your hair—the "weather" here includes a constant fine mist of salt that corrodes metal faster than you’d believe.
Actionable Insights for Your Visit
If you're heading out to enjoy the weather in Point Loma CA, don't just check the general San Diego forecast. It's often misleading for the peninsula.
Instead, look at the "Point Loma North" naval base weather stations or the specialized surf reports for Sunset Cliffs. These give you a much more accurate reading of the wind speed and cloud ceiling.

- Morning People: Expect gray. Plan your hikes at Cabrillo for the morning if you want cool air, but don't expect a view.
- Photography: The "Golden Hour" here is legit, but only if the marine layer stays offshore. Check the "Satellite" view on weather apps. If you see a big white blob sitting over the ocean, it’s coming for you by sunset.
- Boating: The wind picks up around 1:00 PM almost every day. If you’re taking a boat out of a Point Loma marina, try to get your heavy traveling done in the morning when the water is "glassy."
The weather in Point Loma CA is a fickle beast. It’s rarely "perfect" by Florida standards—it’s not tropical. It’s Mediterranean-cool. It’s moody. But once you learn to love the mist and the way the air smells like kelp and salt, you won't want to be anywhere else. Just remember: always keep a sweatshirt in the trunk of your car. You’ll thank me later.
Check the tide charts before heading to the cliffs, as the "weather" also dictates how much beach you actually have to stand on when the tide comes in.
