Aloha! You ever wonder why one side of the island is all green and rainy, and the other side is hot and dry like a desert? Growing up here in Hawaii, I used to ask my uncle that all the time. He’d chuckle and say, “Eh, it’s ‘cause Hawaii get one crazy kine mix of climates!” And he was right. Believe it or not, we’ve got 10—yeah, TEN—different climate zones right here in these islands. It’s kinda mind-blowing when you think about it.

So if you’re thinking about moving to Hawaii or just cruising around to see where you might wanna settle, let me give you the scoop on our different weather zones. Maybe you’ll find your perfect spot!

Why Hawaii’s Weather Is So Unique

Okay, first off, we’re in the middle of the Pacific Ocean—kind of out there, yeah? Then you add in our huge volcanoes, trade winds blowing in from the northeast, and all the elevation changes from sea level to over 13,000 feet, and boom—you get all these microclimates packed into one place. You can be roasting on the beach in Kona, then drive up to Mauna Kea and freeze your slippers off. True story!

The 10 Hawaii Climate Zones (Broke Down Simple)

1. Tropical Rainforest – Like Hilo on Big Island or Hana on Maui

If you love green, this is the place. It rains pretty much every day, but that’s why the waterfalls are always going off. Super lush, everything grows like crazy. Bring your rain jacket though, ‘cause you’re gonna need it.

2. Tropical Monsoon – Think Hanalei on Kauai or Kaneohe on Oahu

You still get lots of rain, but not as constant. Usually wet season and dry season kind stuff. The valleys are unreal here—like something outta a movie.

3. Tropical Savanna – Leeward Side, Like Kihei on Maui or Kona on Big Island

You want sunshine? Come leeward side. Barely any rain, so your beach days are always solid. It’s hot though—make sure you hydrate!

4. Hot Semi-Desert (Steppe) – Waikoloa or Ka’u on Big Island

Super dry, lots of lava rock and scrubby bushes. Waikoloa’s got fancy resorts, but it’s pretty dry out there.

5. Hot Desert – Kawaihae Area, Big Island

Believe it or not, this is our desert. Hardly any rain, plenty sun. Kawaihae’s always hot and dusty. If you like dry heat, this is your spot.

6. Temperate Oceanic – Upcountry Maui (Kula) and Waimea Big Island

Now we talking cooler weather. This is where you go if you like sweaters and cozy vibes. Great place for farming and ranching too—lots of paniolo (Hawaiian cowboys) around here.

7. Temperate Continental – High Elevations Like Mauna Loa

Kinda cold up here. Not a lot of folks live this high up, but if you ever go hiking or exploring, bring warm clothes. Gets chilly fast.

8. Subarctic – Summit of Mauna Kea

This one’s hardcore. Snow in Hawaii? Yup, every winter Mauna Kea gets dusted. Only the astronomers hang out here long term. Not exactly beach weather.

9. Alpine – Top of Mauna Kea

Same deal. You’re way up there. Super cold, thin air, no trees. But brah, the stars up there? Unbelievable.

10. Periglacial – The Ice Zone

You probably won’t be hanging out here unless you’re a scientist, but it’s cool to know Hawaii has periglacial zones. Mauna Kea’s summit has conditions like the Arctic!

How to Pick Your Perfect Hawaii Climate Zone

So, you might be wondering, “Eh, where should I live?” Well, here’s the lowdown:

  • You like it hot and dry? Leeward sides like Kona, Kihei, or Kohala Coast are sunny almost every day.
  • You prefer cool, crisp air? Head up to Upcountry Maui or Waimea on Big Island. Nights get chilly—sometimes you need a blanket!
  • You love green and rain? Go windward side—Hilo, Hana, Kaneohe. But bring an umbrella, guarantee.

The beauty is, you can pretty much find any kind of weather you want without even leaving the islands.
