You're looking at the calendar, seeing November creep up, and wondering if a trip to Hawaii is a gamble. Honestly? Most people think the "wet season" means ruined vacations and constant gray skies. That’s a massive misconception. If you’re eyeing the weather in Oahu November, you’re actually looking at one of the most interesting times to be on the island.
It’s a transitional month. Basically, the island is shifting from its parched summer state into its lush, green winter coat. You’ve got warm water, cooling air, and the return of the legendary swells.
But there’s a catch. Or a few catches.
Depending on where you stand on the island, you might experience a totally different climate than someone just ten miles away. Let’s break down what’s actually happening on the ground.
The Reality of Rainfall and "The Wet Season"
Yes, November is technically the start of the wet season in Hawaii. However, don't picture a Seattle-style drizzle that lasts for three days straight. Rainfall here is usually local, intense, and over in fifteen minutes.
Statistically, Honolulu sees about 2.2 to 3 inches of rain in November, but that number is misleading. If you stay in Waikiki, you're in a "leeward" (dry) zone. You might see a few rainbows and a quick morning sprinkle. But if you drive over to the "windward" side—places like Kailua or Kaneohe—the clouds get stuck on the Ko'olau Mountains. It rains there way more often.

What the 2025-2026 La Niña Means for You
We are currently in a weak La Niña cycle. According to NOAA’s Climate Prediction Center, this typically translates to slightly wetter-than-average conditions for the Hawaiian Islands through early 2026.
For your November trip, this doesn't mean you'll be swimming in the streets. It just means the trade winds might be a bit more consistent and those "mauka" (mountain) showers could be more frequent. It's actually a blessing for the island's foliage, which has been pretty dry lately.
Temperature: Is It Still "Beach Weather"?
Short answer: Yes.
Longer answer: You’ll barely notice it's "winter." Daytime highs in November hover around 81°F to 84°F. That’s plenty hot when you’re sitting on the sand at Lanikai. The real change is at night. Lows drop to about 70°F or 71°F.
- Humidity: It’s around 67-72%. It feels "tropical" but rarely "suffocating" like it does in August.
- Water Temp: The ocean is still a balmy 79°F. It’s actually warmer than the air during those early morning sessions.
- Daylight: You get about 11 hours of sun. Sunset is usually around 5:50 PM.
If you’re coming from the mainland where it’s currently 40 degrees and sleeting, Oahu in November will feel like a literal furnace. You'll still be in shorts and a T-shirt 95% of the time.
The North Shore vs. South Shore Divide
This is the biggest weather-related factor for your itinerary. In the summer, the North Shore is like a lake—calm, clear, and perfect for snorkeling. In November? Everything flips.
Huge Pacific storms start sending "groundswells" toward the islands. This is when the North Shore earns its "Seven Mile Miracle" nickname. Waves at Waimea Bay or Sunset Beach can jump from 2 feet to 20 feet overnight.
If you aren't an expert surfer, stay out of the water on the North Shore once those swells hit. The riptides are no joke. On the flip side, the South Shore (Waikiki/Ala Moana) stays relatively calm. It’s the safe bet for families and beginner longboarders during the late fall.

What to Actually Pack
People overpack for Hawaii. Period. You do not need a parka. You probably don't even need jeans unless you're planning on a fancy dinner at a place like Senia or Merriman’s.
- A light rain shell: Not for warmth, but for keeping your skin dry during a sudden downpour.
- A "restaurant" sweater: It sounds crazy, but Hawaii loves its air conditioning. It’ll be 80 outside and 65 inside a Cheesecake Factory. You'll want a light layer.
- Reef-safe sunscreen: This isn't just a suggestion; it’s the law in Hawaii. Non-mineral sunscreens (those with oxybenzone or octinoxate) are banned to protect the coral.
- Hiking shoes with grip: If it rains, those red clay trails at Diamond Head or Pillbox become slippery as ice. Flip-flops (slippers) won't cut it.
The "Vog" Factor
Occasionally, the trade winds die down and we get "Kona winds." These come from the south/west. When this happens, sulfur dioxide from the volcanoes on the Big Island can drift up to Oahu. Locals call it "Vog" (volcanic fog).
It makes the sky look a bit hazy and can give sensitive people a scratchy throat. In November, Kona winds aren't super common, but they do happen when a cold front is approaching. If you see a gray, murky horizon but it isn't raining, that's likely what's going on.
Why November is a "Secret" Smart Move
Most travelers wait for the Christmas rush. By going in November, you beat the massive crowds and the "holiday pricing" on hotels. You get the lushness of the rainy season without the full-blown winter storms that sometimes hit in January or February.

Plus, you get to see the big waves. Even if you don't surf, standing on the beach at Banzai Pipeline and feeling the ground shake as a 15-foot wave breaks is a core memory. Just keep your eyes on the horizon and respect the lifeguards.
Actionable Tips for Your November Trip
- Use hyperlocal apps: Don't trust the generic "Honolulu" forecast on your iPhone. Use Windy.com or Ventusky. They show you exactly where the rain clouds are moving in real-time.
- Plan "Rainy Day" backups: If the windward side is soaked, head to the west side (Ko Olina). It’s almost always sunny there. If the whole island is gray, it's a great day for the Bishop Museum or the Pearl Harbor Aviation Museum.
- Check the Surf Report: Before you drive an hour to the North Shore, check Surfline. If the "shaka" icon is red, the waves are massive. Great for watching, dangerous for swimming.
- Sunsets are better now: The slight increase in cloud cover in November actually makes for more dramatic, purple-and-orange sunsets than the clear summer skies. Get to a west-facing beach by 5:30 PM.
