Overview of Brisbane Weather During Christmas
Brisbane sits in a humid subtropical zone, and Christmas marks the start of summer. Expect warm to hot days, high humidity, and those classic afternoon storms. Sea breezes from the coast often shape the conditions.
Typical Temperature Ranges
During Christmas, Brisbane’s daytime highs usually land between 28°C and 30°C (82°F–86°F). Nights stay pretty mild, with lows around 20°C to 22°C (68°F–72°F).
Sometimes, heatwaves hit, especially if winds come from inland. On those days, temperatures can shoot up past 35°C (95°F), but that’s less common closer to the coast.
The sea holds steady at about 25°C (77°F), so swimming feels great. Breezes from Moreton Bay help cool things down in the afternoon.
Rainfall Patterns
December ranks as one of Brisbane’s wetter months. The city usually gets about 120–140 mm of rain, spread over 8–10 days.
Short, intense thunderstorms often form in the late afternoon or evening. These storms can bring heavy rain, gusty winds, and sometimes hail. They don’t last long, but they can mess up outdoor plans if you’re not ready.
You’ll still catch plenty of sun between showers. Most mornings stay dry, and storms usually pop up later in the day.
Humidity Levels
Humidity runs high around Christmas, with averages near 70–75%. The air feels warmer than the number on the thermometer, especially midday.
Even at night, humidity doesn’t really drop, so evenings can feel sticky if there’s not much breeze. Coastal spots get some relief from sea breezes, but inland areas might feel a bit stuffier.
If you’re not used to humid places, long hours outside can feel pretty draining. Drink plenty of water, stick to the shade, and plan activities earlier in the day to stay comfortable.
Daily Temperature Trends in Late December
Late December in Brisbane brings warm days and noticeable humidity. Daytime highs feel hot but rarely extreme, while nights stay mild and comfortable.
The shift from day to night happens gradually, so there aren’t any sharp temperature drops. It’s easy to plan outdoor or evening activities when the weather stays so steady.
Daytime and Nighttime Highs and Lows
In late December, daytime highs usually range from 81°F to 84°F (27°C to 29°C). It’s rare for the temperature to climb above 88°F (31°C). Most afternoons feel warm but manageable, especially near the coast where breezes kick in.
At night, lows hover between 67°F and 70°F (19°C to 21°C). It’s uncommon for nights to dip below 61°F (16°C), so you can leave the heavy layers at home. Even after sunset, the air often feels muggy, and that sticky feeling gets more common as the month goes on.
The daily temperature range sits around 8–9°C (15–16°F). Mornings start out mild, afternoons heat up, and evenings cool off slowly. This consistency makes it easy to plan your day without worrying about big swings in temperature.

Late December is close to Brisbane’s warmest time of year. January gets a bit hotter, with average highs around 29°C (84°F). July cools down, with highs near 20°C (68°F).
Humidity climbs in December, so the air feels heavier than it does in spring or autumn. May and August bring cooler, drier air, and many people find those months more comfortable for being outside.
December offers longer daylight, with nearly 13 hours and 50 minutes of sunshine. The extra sunlight adds to the feeling of heat, even if the actual highs aren’t as extreme as in tropical regions further north.

Humidity stays high, often above 65–70%, which makes the air feel warmer. Mornings are usually clearer, while showers tend to show up in the afternoon or evening.
If you’re visiting, pack a light rain jacket or have some indoor backup plans. Rain doesn’t usually last all day, so you’ll get breaks in the weather.
Thunderstorms and Summer Showers
Thunderstorms are a regular part of December in Brisbane. Warm days around 28°C and coastal moisture make the air unstable, which triggers storms.
You’ll mostly see storms in the late afternoon or evening. These bring lightning, heavy rain, and gusty winds. Most storms pass quickly and leave the sky clearer.
Summer showers can pop up suddenly and get intense for a short time. Streets might flood briefly during big downpours, but water drains away pretty fast.
If you’re planning something outdoors, try to stay flexible. Usually, you’ll get a hot, sunny morning, then a stormy afternoon. That’s just Brisbane’s subtropical rhythm at Christmas.
Sunshine, Daylight Hours, and UV Index
Brisbane’s subtropical weather brings you long, bright days in late December. Expect lots of sunshine, extended daylight, and a UV index that can get seriously high.
Hours of Sunshine
December averages about 333 hours of sunshine, or more than 10 hours per day. That’s a lot of sun—one of the brightest times of the year.
Most days bring clear skies or just a few clouds. Afternoon thunderstorms might roll through, but they’re usually quick and don’t take away from the total sunshine.
Compared to winter months, where you get about 8 hours of sun, December feels noticeably brighter and longer. You’ll have plenty of daylight for outdoor plans.

That’s a big jump in sun exposure around Christmas compared to the middle of the year.

Late December gives Brisbane some of its longest daylight periods of the year. The sun’s up for close to 13 hours and 49 minutes from sunrise to sunset.
You can start your day early and keep going well into the evening. For travelers, that means more time for sightseeing, beach outings, or outdoor dinners.
The change in daylight across the year is hard to miss. In June, the shortest days last just over 10 hours. In December, you get nearly 4 extra hours of light.
Typical daylight ranges:

Longer daylight also means warmer evenings, which makes outdoor gatherings more comfortable.
UV Exposure and Safety
December brings some of the highest UV index levels in Brisbane, often hitting 14 to 15—that’s considered Extreme. At these levels, unprotected skin can burn in under 15 minutes.
Take sun safety seriously. Wear a wide-brimmed hat, sunglasses, and SPF 30+ sunscreen. Reapply sunscreen every couple of hours, especially if you’re swimming or sweating.
Try to stay out of direct sun between 10 a.m. and 3 p.m., when UV peaks. Shade and long sleeves help a lot during these hours.
Even when it’s cloudy, UV levels stay high, so don’t skip protection. The combo of long days and extreme UV makes December a tough month for sun safety in Brisbane.
Humidity and Wind Conditions
December in Brisbane brings warm, moist air and steady breezes. Most days feel humid, and winds shift between calm mornings and breezier afternoons.
Humidity Trends in December
Humidity in December usually sits around 55–65% on average. The air feels damp, especially after it rains, which happens about 12 days in the month. High temperatures and moisture make it feel warmer than it really is.
You’ll notice the humidity most during afternoons when heat and moisture peak together. Evenings are a bit more comfortable, though air conditioning is pretty common in homes and hotels to beat the sticky air.
If you’re heading out in the morning, the air feels fresher and less heavy. Bring water and wear light, breathable clothes to stay cool. The humidity also keeps the city’s greenery lush, which adds to Brisbane’s subtropical charm during the holidays.
Wind Patterns and Speeds
December’s winds in Brisbane average about 4 meters per second (roughly 14 km/h). That’s a gentle to moderate breeze. You’ll see small branches sway and feel a steady flow of air that takes the edge off the heat and humidity.
Winds often shift with local sea breezes, especially in the afternoon. Coastal areas feel fresher, while inland spots might notice the humidity more on calm days. When the wind picks up, it brings a more comfortable balance.
Most travelers find the wind pretty manageable. Dining outside, walking by the river, or hanging out at the beach usually isn’t disrupted by December breezes. You might bring a light jacket, but honestly, the winds are warm—not chilly—this time of year.
Water Temperature and Outdoor Activities
Around Christmas, Brisbane serves up warm air and inviting sea conditions. Hot days and mild evenings make swimming and outdoor recreation both comfortable and popular.
Average Water Temperature
In late December, the sea near Brisbane averages about 24–25°C (75–77°F). That’s warm enough for long swims without feeling chilly.
The water is much warmer than in spring and keeps rising into January. Ocean temperatures don’t change much between morning and evening, so you can swim any time.
The sea feels pleasant for casual swimmers and those planning longer water adventures. Even people who usually find the water cold can handle it. Rain doesn’t cool the water much—showers pass quickly and the sea stays warm.
Best Activities for Christmas Weather
Warm water and hot air make swimming, snorkeling, and paddleboarding great choices. Beaches get busy, but conditions stay good for families and casual visitors.
If boating or sailing is your thing, steady east-northeast winds around 16 km/h (10 mph) are just right—not too strong. Mornings are often calmer, so kayaking or stand-up paddleboarding works well then.
On land, long daylight hours (about 14 per day) give you time for hiking or cycling. Just remember, humidity is high and the UV index is extreme. Plan outdoor fun early or later in the day, and use shade, sunscreen, and protective clothing to avoid sunburn.
Travel Tips for Christmas in Brisbane
Christmas in Brisbane means warm days, sticky air, and, honestly, a pretty good chance of rain. You’ll need to juggle both the sunshine and those surprise showers. Figuring out how you’ll get from the airport to the city is also worth thinking about.
What to Pack for the Weather
By late December, you’ll probably see daytime highs around 28°C. Nights don’t cool off much—usually around 21°C. Humidity can really sneak up on you, and those quick rain bursts? They happen a lot.
I’d go with light, airy clothes like cotton shirts, shorts, or easy dresses. They’ll keep you comfortable.
Definitely toss in a light rain jacket or a compact umbrella. December sees about 12 rainy days, and you don’t want to get caught off guard.
If you’re walking after a shower, waterproof sandals or quick-drying shoes make life easier.
The sun in Brisbane is no joke, so don’t forget sunscreen (SPF 30+ or higher), sunglasses, and a hat.
Planning to swim? The water sits at a lovely 23°C. Pack your swimwear and maybe a beach towel.
Shops, buses, and hotels blast the air conditioning, so a light sweater or thin layer will help you stay comfortable indoors.
A small daypack works well for carrying water, sunscreen, and rain gear while you’re out exploring.
Getting to and from Brisbane Airport
Brisbane Airport (BNE) sits about 14 kilometers northeast of the city center. You’ll find a few transport options, depending on your budget and when you need to get moving.
The Airtrain comes every 15 to 30 minutes, and you’ll usually get to central stations in about 20 minutes. It’s pretty reliable, and you don’t have to worry about getting stuck in traffic.
You can grab tickets online or right at the station. That’s handy if you’re in a rush or just like to plan ahead.
Taxis and rideshare drivers wait at both terminals. A typical taxi ride into the city takes somewhere between 20 and 30 minutes, but if it’s a busy holiday, expect it to take longer.
If you’d rather drive yourself, you’ll find car rental desks inside the terminals. There’s parking near the airport, but just a heads up—city hotels often charge steep daily rates.
Shuttle buses connect the airport with major hotels and holiday spots. They’re a solid choice, especially if you’re hauling extra luggage or traveling with the whole family.
