November is two months wearing one name. Up to about the 20th it is quiet, warm, green and one of the cheapest times of the year to be in Hawaii. From Thanksgiving week onward it prices and fills like a holiday period, because it is one.
If your dates are flexible, the first three weeks are among the best value windows on the calendar, and the best time to visit guide puts them alongside late April to early June for a reason.
The weather, honestly
November is the start of the wet season, and the useful thing to understand is that "rainy season in Hawaii" describes a windward phenomenon rather than a statewide one. The northeast-facing sides get the rain: Hilo, Hāna, the Kōʻolau side of Oʻahu, Kauaʻi's north shore. The leeward sides stay largely dry.
Kona, Waikōloa, Wailea, Kīhei, Waikīkī and Poʻipū are all leeward. If rain is your main worry, that is the answer, and it matters more than the month does.
Daytime highs sit in the low 80s Fahrenheit near sea level and the water is around 78 to 80, which is warmer than most people expect for late autumn.
The surf changes where you swim
North Pacific swell starts arriving in November, which is why the Triple Crown of Surfing runs on Oʻahu's North Shore from November into December. It is genuinely worth watching if you are on Oʻahu, and it is free.
The flip side is that north shore beaches stop being swimming beaches. Waimea Bay, Hanalei on Kauaʻi and Honolua Bay on Maui go from summer-calm to dangerous. Snorkeling moves to the south and west: Hanauma Bay, Kāʻanapali, Wailea, Poʻipū.
This is not a small adjustment. It changes which side of the island you should stay on.
What to pack for November
Everything from the standard packing list still applies. Three things change:
- A light rain shell. Not an umbrella, which is useless in wind. Showers pass quickly and are usually warm, but they arrive without warning.
- One warm layer. Evenings at elevation get cool, and if you are going up Haleakalā or Mauna Kea it is genuinely cold. Sunset boat trips are windier than they look.
- Reef-safe sunscreen. Required by state law, and the sun in November is still strong enough to burn you in twenty minutes.
Long trousers for one or two evenings, closed shoes if you plan to hike wet trails, and nothing heavier than that.
Thanksgiving week
Prices roughly double from the weekend before Thanksgiving through the first days of December. Flights, hotels and cars all move together, and cars in particular run out on Maui and Kauaʻi.
If your dates are fixed to that week, book everything early and refundable, then re-check prices periodically. Free cancellation means holding a booking costs nothing and rebooking costs nothing.
The short days
Sunset in Hawaii in November is around 5:50pm, and there is very little dusk this close to the tropics. Dark means dark, quickly.
That matters for anything involving driving. The Road to Hāna, the Hāna side of Haleakalā and Kauaʻi's north shore roads are all unlit and unforgiving after dark, so a day that starts at 9am ends more abruptly than it would in July. Start earlier than feels necessary.
Check the live numbers
Every month, side by side, is on the Hawaii weather reference: monthly rainfall for five stations plus sea temperature, taken from NOAA. The figures on this page describe a typical year. For the one you are actually travelling in:
- Water temperature, NOAA station 1612340. Live and historic readings from Honolulu Harbor. The monthly averages quoted here are the 34,802 hourly observations, 2021 to 2024 mean from this station.
- National Weather Service, Honolulu. Forecasts and warnings for every island, including the high surf advisories that decide which coasts are swimmable this week.
- National Hurricane Center. Worth a look in the week before you fly between June and November, and worth ignoring the rest of the year.
