Hawaii in December: Your Complete Packing Guide

December in Hawaii is a sweet spot. You get warm, sunny days without the intense summer heat, plus the chance of some dramatic rain showers. The key to packing is versatility — you need beachwear, light layers, and one or two smarter outfits for nicer dinners. Expect daytime highs around 80°F (27°C) and evenings that dip to the mid-60s (18°C).

Forget heavy coats and scarves. You are packing for a tropical climate, but you must respect the trade winds and the occasional downpour. A light jacket or hoodie will be your best friend after sunset. Here is exactly what to bring so you look right and stay comfortable, whether you are on Maui, Oahu, or the Big Island.

Base Layers: Lightweight Fabrics Are Non-Negotiable

Cotton t-shirts and tank tops are perfect for daytime. But you should pack a few pieces made from quick-dry synthetics or merino wool. These fabrics handle humidity better than heavy cotton and dry fast if you get caught in a tropical shower. Linen shirts are also a great choice for men — they breathe well and look sharp.

For women, sundresses and rompers are the easiest option. They are one-piece outfits that go from a beach walk to a lunch spot without fuss. For men, a couple of solid-colored polo shirts and casual button-downs will cover you for most activities. Avoid heavy denim. Jeans are too hot and take forever to dry if they get wet.

Pack a mix of short sleeves and a few long-sleeve options. A light long-sleeve shirt protects you from the sun without feeling heavy. It also gives you coverage for breezy evenings or air-conditioned restaurants.

The Perfect Outerwear: One Jacket Does It All

You need exactly one jacket. Do not pack a bulky winter coat. Instead, bring a lightweight, water-resistant windbreaker. This is the single most useful item you will own on the trip. It blocks the wind, repels rain, and packs down small in your suitcase.

A hoodie or a light fleece is good for cooler evenings, especially if you plan to be on a boat or at a higher elevation like Haleakala on Maui. For the summit of Haleakala at sunrise, you will want a warm layer — temperatures there can drop to near freezing. A packable down jacket is worth the space if you plan to visit volcanoes or do a sunrise summit trip.

For nicer dinners, a linen blazer for men or a light cardigan for women works well. It elevates your look without making you sweat. Most restaurants in Hawaii are casual, but a few upscale spots appreciate a collared shirt or a nice cover-up.

Footwear: The Right Shoes for Every Activity

Your feet will do a lot of work in Hawaii. Bring three pairs of shoes maximum: one pair of sandals, one pair of sneakers, and one pair of dressier shoes.

For sandals, get a pair of rubber or leather flip-flops — locals call them slippers. These are your everyday shoes. They are perfect for beaches, casual walks, and quick trips to the store. Make sure they have a bit of arch support if you plan to walk a lot. Brands like Olukai and Reef offer better support than cheap foam flip-flops.

Your sneakers should be breathable. Mesh running shoes are ideal because they drain water and dry quickly. You will want these for hiking trails, like the Diamond Head summit on Oahu or the Pipiwai Trail on Maui. Do not bring suede sneakers — they will get ruined by water and mud.

For dressier occasions, a pair of loafers for men or stylish flats or wedges for women works well. Wedges are smart for beach dinners because they don’t sink into the sand. Leave the high heels at home — they are impractical for uneven sidewalks and sandy paths.

Swimwear and Beach Essentials

Pack at least two swimsuits. One is always drying while you wear the other. Board shorts for men and one-piece suits or bikinis for women are all acceptable. Bring a rash guard too — it protects your skin from the sun and is useful for snorkeling.

A good beach cover-up is essential. For women, a cotton kaftan or a sarong is lightweight and easy to throw over a wet swimsuit. For men, a quick-dry t-shirt is enough. You will wear your cover-up more than you think — it keeps you comfortable during the walk back from the beach and protects you from the sun.

Bring a wide-brimmed hat for sun protection. A baseball cap works, but a straw or packable sun hat offers better coverage for your neck and ears. Sunglasses are non-negotiable — the Hawaiian sun is intense, and polarized lenses cut through the glare off the water.

Accessories That Matter in Hawaii

Your accessories should be practical, not flashy. Bring a dry bag for your phone, wallet, and keys when you go to the beach or on a boat. These are cheap and prevent catastrophe when a wave crashes over you.

A lightweight backpack or tote is essential for day trips. You will carry water, snacks, a towel, and a jacket. Choose one with a water bottle pocket and a zip closure to keep sand out. A crossbody bag is better than a shoulder bag for crowded areas — it keeps your valuables safe and hands-free.

Do not forget sunscreen and bug spray. These are not fashion items, but they are the most important accessories you will pack. Use reef-safe sunscreen to protect the coral reefs. The Hawaiian sun will burn you in 15 minutes on a cloudy day. Reapply every two hours.

Specific Outfits for December Conditions

December weather is unpredictable. You might have a week of sunshine or a few days of heavy rain. Pack clothes that mix and match so you can adapt.

For a typical day: wear your swimsuit under a t-shirt and shorts. Throw your windbreaker in your bag. That outfit covers you from a morning swim to an afternoon hike. For a nicer dinner: swap the shorts for chinos or a maxi skirt, and add your dressier top or shirt.

If you plan to attend a luau, wear something casual but neat. A floral print shirt for men or a sundress for women is perfect. Do not overthink it — locals wear aloha shirts with jeans or shorts, and it looks great.

Pack a light pashmina or scarf for women. It works as a shawl for air-conditioned restaurants, a sun protector on the beach, or a makeshift pillow on a helicopter tour.

Frequently Asked Questions

Do I need a jacket in Hawaii in December?

Yes, absolutely. Pack a light water-resistant windbreaker or a hoodie. Evenings can feel cool, especially with the trade winds. If you plan to visit Haleakala or Mauna Kea, bring a warm fleece or a packable down jacket.

Can I wear jeans in Hawaii in December?

You can, but you probably won’t want to. Jeans are heavy and hot in the humidity. They also take forever to dry if you get caught in the rain. Choose lightweight chinos, linen pants, or quick-dry hiking pants instead.

What shoes should I not bring to Hawaii?

Leave suede anything at home. Suede sneakers or boots get ruined by water and mud. Also skip heavy leather boots — they are too hot and uncomfortable. Stick with rubber flip-flops, mesh sneakers, and comfortable loafers or flats.

Is it warm enough to swim in Hawaii in December?

Yes. Ocean temperatures in December are around 77°F (25°C), which is comfortable for swimming and snorkeling. You might feel a slight chill when you first get in, but you will warm up quickly. Pack a rash guard for extra warmth if you are sensitive to cooler water.
