What to Wear in Auckland in December
Auckland in December: 22°C / 72°F afternoons, 15°C / 59°F nights, a UV index of 11.5, and the first dry spells of summer.
- Cream cotton button-down — sleeves down over the linen dress while the UV index averages 11.5
- Natural straw hat with a brim all round — shades the face, ears and neck a collar leaves bare
- White linen midi dress — Christmas lunch on Friday 25 December at 22°C / 72°F
- White rose-appliqué knit — 15°C / 59°F once the sun goes at about half past eight
- Tan leather boat shoes — a white rubber sole grips a wet ferry deck
- Bright red packable shell — NIWA still counts 9 wet days, and it folds small between them
- A wool jumper — the average night bottoms out at 15°C / 59°F
- Bare shoulders between 10am and 4pm — a UV index of 11.5
- Flip-flops on the ferry — a wet deck and a gangway, and nothing to grip with
- Heavy dark denim — it holds the heat of a 22°C / 72°F afternoon on the harbour
Pack for a summer spent outdoors. NOAA's figures for Auckland Airport put December at 21.6°C by day and 15.0°C / 59°F at night, and NIWA's record shows three things changing at once. The mean daily maximum UV index at Leigh reaches 11.5, up from 9.8 in November. The wind eases from its spring peak of 21 km/h to 19. And the dry spells start: "Dry spells are common in Auckland during the summer and early autumn," NIWA writes, usually one and often two between December and March. There are still 9 wet days and 87mm, so a shell comes too. Christmas in the Park fills the Auckland Domain on Saturday 12 December, and school holidays begin by the 19th. Cotton and linen, a brim, and shoes for a deck.
December is the month Auckland stops arguing with the wind and starts arguing with the sun. The shell goes into the bag. The brim comes out, and in January the index climbs higher still.
The capsule
01Cream cotton button-down, chest pocketKeep the sleeves down. NIWA's mean daily maximum UV index at Leigh reaches 11.5 in December, and SunSmart NZ puts clothing first of its five steps, ahead of sunscreen. A cream cotton button-down goes open over the linen dress on the Devonport ferry and buttoned over the shorts for lunch in Ponsonby, and at 22°C / 72°F cotton breathes where a synthetic layer sticks.
02White cropped ribbed knit, red rose and green leaf appliquéChristmas in the Park fills the Auckland Domain on Saturday 12 December, its 32nd year since the first concert in 1994, and it runs into the evening. Nights average 15.0°C / 59°F and the sun sets at about half past eight, so bring one knit. A white ribbed crop is light enough for a summer night, and the red rose is the only colour it needs.
03Cornflower-blue vertical-stripe tailored shorts, pleated frontShorts, but pleated and tailored, because a December day here moves from the beach to a Ponsonby lunch table without a change of clothes. Cornflower stripes let air reach your legs at 22°C / 72°F, the pleat keeps them from reading as swimwear, and they take the cream shirt or the rose knit. Put sunscreen on your knees; SunSmart NZ's window runs 10am to 4pm.
04White linen midi dress, short sleeves, tie waistChristmas Day falls on a Friday, and Employment New Zealand lists Boxing Day as observed on Monday 28 December, which gives Monday-to-Friday workers a four-day weekend. White linen to mid-calf covers your legs at an outdoor lunch in 22°C / 72°F heat, the tie waist gives after the second course, and the cream shirt goes over the short sleeves when the table is in the sun.
05Tan leather boat shoes, white soleA December on the Hauraki Gulf means ferry decks, wet gangways and sand, and a white rubber sole grips a wet deck where a flip-flop slides. Tan leather goes with the olive bag and the cornflower shorts, needs no socks at 22°C / 72°F, and still looks dressed at a Viaduct dinner. Rinse the salt off at night and they last the trip.
06Natural straw hat, brown bandYour face, ears and neck are what a cotton shirt leaves bare, and at a UV index of 11.5 they burn first. A hat is the fourth of SunSmart NZ's five steps. Natural straw with a brim that runs all the way round shades all three, the brown band ties it to the boat shoes, and it weighs next to nothing between the beach and the ferry.
07Olive waxed-canvas flap crossbody, brown leather strapWaxed canvas sheds a shower and wipes clean of sand, which matters in a month that brings both the first dry spell and 9 wet days. The olive flap bag sits across your body in the Christmas in the Park crowd, carries sunscreen and a phone, and its brown strap matches the hat band and the boat shoes.
08Bright red hooded packable rain shellDry spells begin this month, but NIWA still counts 9 wet days of 1mm or more and 87mm at the airport, so a shell rides along. A bright red packable one with a hood folds small, goes over the linen dress in a passing shower, and is easy to find in a Domain crowd at dusk. Its red matches the pōhutukawa, which the Department of Conservation says flowers around Christmas.
Day to night
Cream button-down open over the white linen dress · straw hat · tan boat shoes · olive crossbody. The 9am ferry to Devonport, up North Head before ten, lunch in the shade by noon, and the ferry back with the hat in your lap.
White rose-appliqué knit · cornflower-striped shorts · tan boat shoes · red shell in the olive crossbody. Christmas in the Park at the Auckland Domain on 12 December, on the grass from late afternoon, the knit on as the light goes at about half past eight.
A suggested look — white cropped rib knit with a red rose appliqué, cornflower blue striped tailored shorts, cream crew socks, tan penny loafers.
What to avoid
- A wool jumper — nights average 15°C / 59°F
- Bare shoulders from 10am to 4pm — a UV index of 11.5
- Flip-flops on the ferry — a wet deck and gangway need grip
- Heavy dark denim — it holds the heat of a 22°C / 72°F afternoon
- Leaving the shell at the hotel — 9 wet days still fall
Frequently asked questions
NOAA NCEI's figures for Auckland Airport, from 29 complete Decembers, give an average high of 21.6°C and a low of 15.0°C / 59°F. NIWA's Climate and Weather of Auckland records 87mm of rain at the airport across 9 days of 1mm or more, and about 13 days with any measurable rain. The mean wind drops to 19 km/h from November's 21. NIWA puts the mean daily maximum UV index at Leigh at 11.5, and notes that dry spells, 15 days or more with under 1mm on any day, come usually once and often twice between December and March. Daylight holds near 14h 40m.
A cream cotton button-down, a white cropped knit with a rose appliqué, cornflower-striped tailored shorts, a white linen midi dress, tan leather boat shoes, a natural straw hat, an olive waxed-canvas crossbody and a bright red packable rain shell. That covers a 22°C / 72°F afternoon under a UV index of 11.5, a 15°C / 59°F evening at Christmas in the Park, and the odd shower among 9 wet days. Add swimwear and sunscreen. Leave the wool, the heavy denim and the ferry flip-flops at home, and pack the shell even in a dry spell.
Coca-Cola Christmas in the Park is on Saturday 12 December 2026 at the Auckland Domain, its 32nd year since the first concert in 1994. It is outdoors and runs into the evening, so dress for two temperatures: 22°C / 72°F in the afternoon and a 15°C / 59°F night after a sunset at about half past eight. Wear shorts or a linen dress with a light knit to pull on later, flat shoes for the grass, and a hat until the sun drops. Carry a packable shell in a crossbody in case of a shower. Christchurch holds its own concert on 28 November.
Early December for events before the school holidays, late December for the public holidays. Christmas in the Park is on Saturday 12 December, and Sunday 6 December is the Santa Parade's rain date. Schools finish no later than Friday 18 December. Christmas Day is Friday 25 December, and Employment New Zealand lists Boxing Day as Saturday 26 or Monday 28 December. New Year's Eve is not a public holiday. Last year the Sky Tower ran lasers and projections from 9pm and a five-minute fireworks display at midnight; the 2026 programme is not yet announced.
Warmer, calmer and harder on your skin. NOAA's airport figures give December 22°C / 72°F and 15°C / 59°F against November's 19°C / 66°F and 13°C / 55°F. NIWA counts 9 wet days in both, though December's 87mm is more than November's 72mm, and the mean wind eases from 21 km/h to 19 as dry-spell season begins. The UV index at Leigh rises again, from 9.8 to 11.5. November's capsule needed a cardigan and a sun top under a shell. December swaps them for linen, shorts, a straw brim and boat shoes. Our November guide covers the cooler month.
White and cream cotton, linen, flat shoes and one red. Juliette Hogan studied fashion and textile design at Parsons in New York, founded her label in 2004 and opened her first store in Ponsonby in 2007; the brand is known for its tailoring, which is what a pleated short or a linen dress needs to go from the beach to lunch. The one colour to add is red. The Department of Conservation writes that "The blazing red flowers of pōhutukawa around Christmas time have earned this tree the title of New Zealand's Christmas tree."
