What to Wear in Hawaii in December (Women): Beach Days, Rain and Mountain Cold

The short answer

Pack warm-weather clothes with a rain plan: breathable dresses and tops, shorts, swimwear and sandals, plus a light rain jacket and a layer for evenings. December is warm at sea level but often wetter, and windier on some coasts. Mountain sunrises need real cold-weather layers, even in Hawaii.

What is the weather like in Hawaii in December?

Warm, usually with short bursts of rain. Near sea level, daytime highs are commonly around the upper 70s to low 80s Fahrenheit, and nights are often in the mid-60s to low 70s. December falls in Hawaii's wetter season, though rain tends to be heavier on windward, northeast-facing coasts than on the sheltered leeward sides.

Elevation changes everything. Upcountry areas are noticeably cooler, and high summits can approach or drop below freezing at night. Check the National Weather Service forecast for your specific island and area just before you pack, because microclimates vary a lot within short distances.

What to pack for a week

This fits into a carry-on and covers beach days, a rainy afternoon, and one nicer dinner. Choose a small color palette so everything mixes.

Two swimsuits and one light cover-up.
Two breathable sundresses, one of which works for dinner.
Two pairs of shorts or a pair of linen pants, plus three light tops.
One light rain jacket with a hood, and one thin cardigan or denim jacket.
One pair of dressy flat sandals, one pair of walking sneakers, and water shoes if you're planning rocky beaches.
A sun hat, sunglasses, and mineral sunscreen with zinc oxide or titanium dioxide. Hawaii bans the sale of sunscreens containing oxybenzone or octinoxate without a prescription, and Maui County restricts sale and use to mineral formulas.
One warm outfit only if you're planning a summit trip.

What should you wear to dinner?

Resort casual covers most restaurants: a sundress, a linen jumpsuit, or a silk-feel top with wide-leg pants and flat sandals. Higher-end hotel restaurants may ask for something a little dressier, so check before booking, but you rarely need a formal outfit.

Bring a light layer for an outdoor table, since evening breezes can feel surprisingly cool after a day in the sun. A long dress can catch the wind, so choose one with some weight, or pick a midi that won't lift. Small gold hoops and a simple clutch are plenty.

What about rain and wind?

Showers are often brief, and a thin hooded rain jacket handles most of them better than an umbrella, which can struggle in trade winds. Fast-drying fabrics help too. Light polyester and linen dry far sooner than denim or heavy cotton, which stay damp for hours in humid air.

On windy days, choose a skirt with some weight or wear shorts beneath it. Tie long hair back, or wear a low braid, since hair and salt air will tangle fast. A hat with an inner band or chin cord stays on far better than a floppy one.

How do you dress for a mountain sunrise?

If you plan to see sunrise at a summit, you need true cold-weather layers. Temperatures at high elevations can be around freezing before dawn, with strong wind on top. Wear long pants, closed shoes, a warm knit, an insulated or wind-resistant jacket, a beanie and gloves, then peel them off at the car once the sun comes up.

Check rules with the park or mountain before you go. Haleakala National Park, for example, requires an advance reservation for most private vehicles entering the summit area between 3 and 7 a.m., and this kind of rule can change. Hotel blankets aren't enough, so pack a real layer or plan to skip the summit.

What should you wear to the beach and on a hike?

Sun exposure can be intense in Hawaii even in winter, so a rash guard or a loose long-sleeved cover-up is useful for long water days, along with a wide-brim hat. Beach sand and reef edges are rough on delicate sandals, so wear water shoes on rocky shorelines. Winter surf can be strong on north-facing coasts, so obey posted warnings before you go in.

For a hike, wear closed walking shoes with real tread, since trails can be muddy after rain. Choose quick-drying shorts or leggings and a breathable top, and carry your rain layer. Red dirt can stain light clothing permanently, so don't wear your favorite white pieces on a trail.

Questions people ask

Is it warm enough to swim in Hawaii in December?

Yes, for most people. The ocean stays comfortable, though conditions vary by coast. Winter surf can be strong on north-facing shores, so check conditions and posted warnings.

Do you need a jacket in Hawaii in December?

Bring a light one for evenings and rain. You'll only need a warm jacket if you're heading to higher elevations or a summit.

What do people wear in Hawaii at Christmas?

Mostly light dresses, aloha prints, and casual resort clothes. For a Christmas dinner, a nicer sundress or a linen outfit with sandals is usually enough.

Can I wear jeans in Hawaii in December?

You can, especially at night or upcountry, but they're slow to dry and can feel hot at sea level. Linen pants are usually more comfortable.

The takeaway

Pack for warmth, plan for rain and wind, bring one nice dinner outfit, and pack real layers only if a summit is on your list.
