Rainfall and Precipitation Patterns
December on the Gold Coast brings warm, humid weather and quite a bit of rain. You’ll see a mix of sunny spells and showers since the month falls in the wetter part of the year.
Average Rainfall in December
December kicks off the wet season here. Rainfall rises compared to the drier winter, with totals averaging about 120–150 mm for the month.
That’s more than you’d get in September or October, but a bit less than the February peak. Rain often arrives in quick, heavy bursts instead of long, slow drizzles.
Afternoon thunderstorms pop up a lot, fueled by the heat and humidity. These storms bring fast downpours, but usually clear out after a few hours.
The rain and sunshine together keep the landscape green and lush. If you’re visiting, it’s smart to plan for both outdoor fun and indoor options, since weather can change fast.
A lightweight raincoat comes in handy.
Frequency of Rainy Days
December usually has 10 to 12 rainy days. That doesn’t mean it rains all day—showers are scattered, so you’ll still get lots of dry, sunny hours.
Subtropical systems and sea breezes drive the rainfall pattern, bumping up the chance of late-day storms, especially near the coast.
Since showers are quick, you can still enjoy most outdoor plans. Mornings are often clearer, and afternoons tend to bring a higher chance of rain.
If you want to avoid interruptions, plan key activities earlier in the day. Rainy days also bring a welcome break from the heat, making things feel a bit more comfortable.
Humidity and Comfort Levels
Christmas on the Gold Coast means high humidity and warm temps, which really affect how comfortable you feel outside. The extra moisture makes the heat feel stronger, and that shapes what you do during the holidays.
Average Humidity Around Christmas
December clocks in with an average humidity of about 80%. It’s one of the muggiest times of the year, right as the wet season kicks in.
Nights feel muggy, and mornings often start sticky and stay that way. Humidity combines with daytime highs near 29°C (85°F), so the air feels warmer than the thermometer says.
Evenings stay mild, around 19°C (67°F), but the air’s moisture makes it feel warmer. Compared to winter, when humidity dips to 55–70%, December is noticeably heavier.
The rise ties back to summer rainfall, with around 144 mm (5.7 in) over 12 days. That steady climb in moisture gives the holidays a real tropical vibe.
Effects on Outdoor Activities
The heat and humidity shape how long you’ll want to stay outside. Activities like walking, cycling, or beach sports can feel more tiring since your body sweats more but cools less.
If you’re planning outings, try scheduling the most active stuff early in the morning or later in the afternoon. Midday is usually the most uncomfortable, especially under the sun.
At the beach, the humid air makes the sea breeze feel amazing. Still, be ready for sudden showers and higher UV.
Light clothes, sunscreen, and lots of water are musts if you want to enjoy Gold Coast weather at this time of year.
Sunshine Hours and UV Index
Around Christmas, the Gold Coast gets long daylight hours and intense sun. You’ll see plenty of sunshine for outdoor plans, but the UV levels are no joke—sun protection is a must.
Typical Sunshine Duration
December brings some of the year’s longest days. You’ll usually get 7–9 hours of direct sunshine per day, with daylight lasting about 13.5–14 hours.
That’s a lot of time for the beach, surfing, or just exploring outdoors. Warm summer temps, with highs around 25–27°C (77–81°F), and mostly clear skies make things feel bright and inviting.
Clouds show up sometimes, but even on partly cloudy days, the sun stays strong enough for tanning or sports. Compared to winter, there’s a big jump in sunshine, which is part of why December is so popular for holidays.
If you’re planning to be outside for a while, try to schedule things for earlier or later in the day to dodge the harshest sun.
| Month | Avg. Sunshine (hrs/day) | Daylight (hrs) |
|---|---|---|
| June (winter) | 5–6 | ~10.5 |
| December (summer) | 7–9 | ~13.5–14 |
UV Index and Sun Safety
The UV index in December often hits very high to extreme levels. Around midday, readings of 10–12 are common—you can burn in under 15 minutes if you’re not careful.
Use broad-spectrum sunscreen (SPF 30 or higher), reapply every couple of hours, and don’t forget protective clothing, sunglasses, and a hat.
Staying in the shade between 10 a.m. and 3 p.m. helps avoid overexposure. Even on cloudy days, UV rays still get through.
Sea breezes can fool you into thinking the sun isn’t strong, but they don’t block UV. If you’re swimming or surfing, remember that water reflects sunlight and boosts your exposure.
Kids and folks with fair skin need to be extra careful. UV-protective swimwear and limiting direct sun during peak hours make for a safer, more fun holiday.
Wind and Sea Conditions
December brings steady, manageable winds along the coast and warm ocean temps. These factors shape how comfortable it feels on the beach and how safe the water is for swimming or other activities.
Wind Speeds in December
Average wind speeds in December range between 12–18 km/h. Breezes usually blow in from the northeast during the day, bringing humid air from the ocean.
At night, winds might shift slightly offshore, so beaches often feel calmer. These winds rarely get strong enough to mess up outdoor plans, but they can make the heat feel less intense.
Sometimes summer storms bring quick gusts, which can make the surf choppy for a bit. If you’re boating or sailing, check the marine forecast—things can change fast.
Beach and Ocean Conditions
The sea temperature in December sits around 24–25°C (75–77°F). The water feels great for long swims, especially in the hotter afternoons.
Surf conditions change with wind and tides. Northeasterly winds can make the water a bit choppy, while mornings are often smoother for swimming.
Lifeguards set up flags for safe swimming zones every day, and it’s smart to stick to their advice.
Surfers get consistent small to medium waves in December. Swimmers should watch out for stronger rips after storms or during spring tides.
If you’re not experienced in the ocean, head to patrolled beaches and stay between the red and yellow flags.
What to Pack and Travel Tips
December on the Gold Coast means warm days, mild nights, and a good chance of rain. Pack lightweight clothes for the heat, but also bring things for quick showers or breezy evenings.
A little planning goes a long way, so you can enjoy both the beaches and the city without getting caught off guard.
Recommended Clothing
During the day, temperatures usually hover between 26–28°C. At night, things cool down to about 20–21°C.
If you want to stay comfortable in the humidity, pack light, breathable fabrics like cotton or linen shirts, shorts, or skirts.
You’ll definitely want a swimsuit—the ocean sits at a lovely 23°C and swimming feels fantastic. For the beach, grab some flip-flops or sandals, but don’t forget comfortable walking shoes if you plan to explore markets, trails, or maybe a theme park.
Toss in a light jacket or long-sleeve shirt for those cooler evenings or if you end up somewhere with blasting air conditioning. Sun protection matters here, so bring a wide-brimmed hat, sunglasses, and sunscreen. Those long daylight hours and the strong UV index can sneak up on you.
Since December tends to bring rain, I suggest packing a compact umbrella or a light waterproof jacket. Quick-dry clothing can be a lifesaver if a sudden downpour catches you off guard.
Weather-Related Travel Advice
Rain usually hits about 12 days in December, with totals reaching around 118 mm. The showers tend to be short, but they can get pretty heavy. So, it’s usually smarter to plan outdoor stuff for the morning when the weather looks clearer.
Humidity averages around 69% and honestly, that can make afternoons feel a bit warmer than you’d expect. It helps to stay hydrated, wear loose clothes, and just take breaks in the shade or somewhere with air conditioning.
If you’re driving, watch out—sudden rain can make roads pretty slippery. Give yourself extra time and steer clear of any flooded spots.
Thinking about a beach day? Always check local surf and safety warnings. Summer storms sometimes kick up strong currents, so stick to swimming between the red and yellow flags where lifeguards keep an eye out.
