Checking the weather Long Beach tomorrow is basically a survival skill if you live anywhere near Ocean Blvd or the Peninsula. It’s tricky. You think you’re getting a standard SoCal postcard day, and then the marine layer decides to park itself over the Queen Mary for eight hours, dropping the temperature by ten degrees in a heartbeat.
Right now, the data from the National Weather Service and local stations near Daugherty Field shows a bit of a shift coming. It isn't just "sunny and 75." We are looking at a classic coastal transition. If you're heading to Belmont Shore or trying to catch a boat to Catalina, you need to know that the morning is going to feel significantly different than the late afternoon.
The Morning Fog: A Long Beach Special
Early birds are going to get hit with that thick, salty mist. It’s the "May Gray" or "June Gloom" vibe, even if we aren't in those months. Expect visibility to be a bit low if you're driving the 710 south into the Port area around 7:00 AM.
Thermometers will probably hover around 58 to 61 degrees when you first step out for coffee. It’s damp. That kind of damp that makes your hair go wild and makes the pavement look like it rained when it definitely didn't. Most of this is driven by the temperature differential between the inland deserts and the cold Pacific current. As the inland air heats up and rises, it literally sucks this ocean air onto our streets.
Don't cancel your breakfast plans at The Breakfast Bar just yet. By 11:00 AM, the sun usually wins the fight. The ceiling of clouds will start breaking up, moving from a solid gray sheet to those puffy, scattered bits that let the UV rays through.
Predicting the Highs: Weather Long Beach Tomorrow Afternoon
By the time 2:00 PM rolls around, the weather Long Beach tomorrow should be peaking. We are looking at a projected high of roughly 72 degrees near the water, though if you move just a few miles inland toward Lakewood, you can easily add five degrees to that number.
The humidity is going to stay relatively low, probably around 45% or 50% once the fog clears. That’s the sweet spot. It feels warm but not sticky. However, the wind is the variable that most people ignore. Usually, we get a sea breeze kicking in after lunch. Expect gusts between 10 and 15 mph coming off the San Pedro Bay.
It’s enough to blow an umbrella over at Rosie’s Dog Beach if you haven’t anchored it deep in the sand.
Why the "Daily Average" is a Lie
Most apps tell you one number. 68. 72. Whatever. But Long Beach is a city of microclimates. The Pike behaves differently than El Dorado Park.
- Near the Lighthouse: The breeze is constant. It will always feel 3-4 degrees cooler than the app says because of the wind chill off the water.
- Near the Airport: This is where the official "Long Beach" temperature is recorded. It’s often the warmest spot in the city because it lacks the immediate cooling of the breakwater.
- The Canals in Naples: These areas trap moisture. Expect it to stay "chillier" longer into the afternoon than the rest of the neighborhood.
What to Wear (The Local Strategy)
Honestly, if you go out in a heavy parka, you’ll be sweating by noon. If you go out in a tank top at 8:00 AM, you’ll be shivering. The "Long Beach Uniform" exists for a reason: layers. A light hoodie or a denim jacket over a tee is the only way to survive the 15-degree swing we’re expecting tomorrow.
Sunscreen is non-negotiable. Even when it’s cloudy in the morning, the UV index is expected to hit a 6 or 7 tomorrow afternoon. That's enough to give you a nasty burn during a walk through the Aquarium of the Pacific's outdoor exhibits if you aren't careful. People forget that the water reflects those rays.
Marine Conditions and Surf Report
For the boaters and surfers, the weather Long Beach tomorrow includes a slight swell. We are seeing a mix of groundswell from the WNW and a smaller southern swell. It’s not going to be epic at the Peninsula—the breakwater kills most of that—but if you’re heading just past the jetty towards Seal Beach, you might see 2-3 foot sets.
Water temperature is currently sitting around 62 degrees. That is "full wetsuit" territory for most human beings. Unless you’re one of those local legends who swims at the Alamitos Bay Yacht Club in trunks year-round, don't forget the neoprene.
The tide schedule is also worth noting:
- High tide is hitting in the early morning, which might eat up some of the narrow beach space.
- Low tide will bottom out in the late afternoon, exposing some of those cool tide pools and making it a great time for a beach walk.
Comparing Long Beach to Our Neighbors
Why does it feel different here than in Santa Monica or Newport? It's the geography. The Palos Verdes Peninsula acts like a giant shield for us. It blocks some of the heaviest winds but also traps the air.
Tomorrow, Santa Monica might be five degrees cooler because they lack that southern protection. Meanwhile, Huntington Beach might be slightly warmer because their coastline angles differently toward the sun. Long Beach sits in this weird, protected pocket that makes our weather remarkably consistent, if a bit predictable once you know the signs.
Expert Insight: The Catalina Effect
There's an old local trick: look toward Catalina Island. If you can see the island clearly from the shore tomorrow morning, the marine layer is thin and will burn off fast. If the island is completely swallowed by mist, expect a "gray-out" until at least 1:00 PM.
Weather stations near the Port of Long Beach are currently reporting a steady atmospheric pressure, which suggests no major storms or surprises are on the horizon. We aren't seeing any "Santa Ana" wind signals either. Those hot, dry winds from the desert usually stay away this time of year, but when they do show up, they flip the script and make the beach the hottest place in the county. Not tomorrow, though. Tomorrow is purely maritime.
Evening Outlook and Nightlife Weather
If you're planning to hit Pine Avenue or the 2nd & PCH area tomorrow night, bring the jacket back out. As soon as the sun dips behind the Palos Verdes hills—usually around 5:30 or 6:00 PM—the temperature will plummet.
We are looking at a drop back down to the low 60s by 8:00 PM and likely hitting a low of 54 degrees overnight. It’s perfect "fire pit" weather. The air will be still, the humidity will climb back up, and that familiar ocean scent will settle back over the city.

Real-World Action Steps for Tomorrow
To make the most of the day, you have to play the clock.
Start your outdoor errands or heavy exercise (like running the stairs at Cherry Beach) before 9:00 AM while it’s still cool and shaded. You’ll perform better without the sun beating down on you.
Save the beach lounging or outdoor dining for the 1:00 PM to 4:00 PM window. This is when you'll get the maximum warmth and the best light for photos of the harbor.
Check the Air Quality Index (AQI) if you have asthma or respiratory issues. Being so close to the ports of Long Beach and Los Angeles, we sometimes get "moderate" air quality ratings when the wind dies down and traps ship emissions near the coast. Tomorrow’s breeze should keep things "Good" to "Moderate," but it’s always worth a quick look at the South Coast AQI map before a long bike ride.
Finally, if you're commuting, remember that the 405 and 710 corridors react poorly to the morning mist. People drive like it’s a blizzard just because there’s a little fog. Give yourself an extra ten minutes if you're heading toward North Long Beach or Signal Hill in the early hours.
The weather Long Beach tomorrow is shaping up to be a classic, temperate Southern California day. It’s not dramatic. It’s not record-breaking. It’s just Long Beach doing what it does best—staying cool, breezy, and perfectly unpredictable for anyone who doesn't check the marine layer forecast.
Keep an eye on the flag at the end of the Belmont Pier. If it's pointing toward the Queen Mary, you’ve got a standard day ahead. If it’s whipping toward the shore, grab a heavier coat.
