Brisbane Weather Month by Month

Brisbane's weather follows a clear rhythm through the year, but the details matter if you're planning a trip, a move, or even just a weekend away. This month-by-month walkthrough covers typical temperatures, rain, humidity and storms, plus what each month is genuinely good for. Treat the figures as

How to read this guide

Brisbane is humid subtropical, so the year splits into a warm, wet, stormy half (roughly October to March) and a mild, dry, sunny half (roughly April to September). The temperatures below are typical daytime highs and overnight lows; humidity and storm risk shift the "feel" as much as the numbers do. For the bigger picture behind these months, see our seasons explained guide and the main complete guide to Brisbane weather.

A useful habit before you read on: the months that share a season can still feel surprisingly different from one another. Early summer is not the same as the wet peak of February, and the gentle warmth of September is a world away from the storm-prone edge of November. The walkthrough below highlights those within-season shifts so you can pick your timing precisely rather than just by season.

Summer: December, January, February

December

Summer arrives in earnest. Highs typically sit around 29°C with warm, humid nights near 20°C. Storm season is well underway, so expect humid afternoons that can build into evening thunderstorms. December is festive and lively, great for pool days, river walks and outdoor events, but pack for heat and keep an eye on the radar later in the day.

January

Usually the hottest, stickiest month. Highs around 29–30°C, high humidity, and the heaviest rainfall of the year, often delivered in intense bursts. Afternoon and evening storms are common. January suits beach trips, water-based activities and early-morning outings before the heat peaks. It's not the month for strenuous midday sightseeing.

February

Much like January: hot, humid and wet, with highs near 29–30°C. This is often the wettest stretch, so flooding can occur after sustained downpours. The upside is a lush, green city and warm, swimmable conditions. Stay flexible with outdoor plans and check the rainfall guide if you want to understand the wet-season patterns in more depth.

Autumn: March, April, May

March

The transition begins. Still warm and fairly humid with highs around 28°C, but storms start to ease as the month goes on. March is a lovely shoulder month: warm enough for the water, but with the worst of the humidity beginning to lift. A strong pick if you want summer warmth with slightly calmer conditions.

April

One of the most pleasant months of the year. Highs around 26°C, noticeably lower humidity, fewer storms and comfortable nights cooling to the mid-teens. This is excellent weather for sightseeing, hiking, markets and day trips. If you're choosing when to come, our best time to visit Brisbane guide rates these autumn months highly.

May

Autumn settles into something close to ideal. Warm, dry, sunny days near 24°C, fresh mornings, and very low storm risk. Nights start to feel cool. May offers reliable, comfortable conditions and is one of the best months for outdoor exploring without summer's humidity.

Winter: June, July, August

June

Winter begins, mild and dry. Days typically reach around 21–22°C under clear skies, while nights drop to roughly 10°C. Rain is uncommon. Sunny afternoons are perfect for sightseeing, though you'll want a jumper after dark. Don't be fooled by the cooler air; the UV can still be high, so keep sun protection on.

July

The coolest month, but still gentle by most standards. Highs around 21°C, crisp nights near 9–10°C, occasionally dipping into single digits, and reliably blue skies. Frost is very rare in the city. July is dry, bright and comfortable: arguably the most dependable sightseeing weather of the year, with cool, clear conditions ideal for walking.

August

Still mild and dry with highs near 22–23°C, but you'll feel the days lengthening and warming. Afternoons can turn breezy. August continues the winter sweet spot, sunny and pleasant, though the air starts edging back towards warmth by month's end. For why locals love this stretch, see seasons explained.

Spring: September, October, November

September

Spring brings warming, mostly dry weather. Highs climb to around 25°C with comfortable humidity and low storm risk early on. September is delightful: warm sunny days, blooming jacarandas later in the season, and easy outdoor conditions before the wet returns.

October

Warming further, with highs near 27°C. Humidity begins to build and the first storms of the season can appear, marking the start of storm season proper. October is still largely pleasant and a fine shoulder month, but afternoons can turn unsettled later in the month, so keep an eye on the forecast.

November

The lead-in to summer. Highs around 28°C, rising humidity, and an increasing chance of afternoon and evening thunderstorms, including the occasional hail-bearing "Black Nor'easter". November is warm and vibrant but increasingly storm-prone, so plan outdoor activities for earlier in the day and stay flexible.

Understanding the wet and dry halves

Step back from the individual months and a clean two-part pattern emerges. The warm half of the year, roughly October through March, carries almost all of Brisbane's rain and nearly all of its storms. Within that window, the depth of the wet season sits in January and February, when downpours are heaviest and most frequent. The cool half, roughly April through September, is the dry, settled, sunny stretch, with July the driest, brightest and coolest point.

This matters because it reframes how you read the calendar. If reliable sunshine and dry days are your priority, you're aiming squarely at the cool half. If warm water and a lush, tropical-feeling city appeal more, the warm half delivers, with the trade-off of humidity and the chance a storm reshuffles your afternoon. Knowing which half you're in tells you most of what you need before you even check a single day's forecast.

Quick picks by purpose

Best all-round weather: April, May, June, July, August, September.
Sunny sightseeing with low rain: the winter trio, June to August.
Warm-water and beach trips: December to March (accepting humidity and storms).
Shoulder-season balance: March, April, September and October.
Storm-watching and lush green scenery: the summer months, especially January and February.

Packing and planning by month

A quick rule of thumb runs through the year. From December to March, pack for heat and humidity: light, breathable clothing, swimwear, a rain jacket or compact umbrella for storms, and plenty of sun protection. April and May ease into comfortable warmth, so add a light layer for cooler mornings. June to August call for t-shirts by day and a jumper for cool nights, with the occasional warmer layer if you feel the cold. September to November swing back towards warm and increasingly humid, so light clothing returns, along with the rain jacket as storm season builds.

One constant applies to every single month: sun protection. Brisbane's UV index is very high to extreme for most of the year, including on cool, clear winter days when burning feels unlikely. Sunscreen, a hat and sunglasses belong in your bag regardless of the date on the calendar.

A note on year-to-year variation

These are typical patterns, not guarantees. Brisbane can throw a warm spell into winter, a dry patch into summer, or an early storm into spring. Broader influences can nudge a whole season wetter or drier than usual, so one January might be relentlessly wet while another stays comparatively dry. That's exactly why month-by-month averages are a starting point, not a substitute for current information, and why it pays to check conditions close to your dates rather than relying on the long-term picture alone.
