Brisbane, where it lies

The climate of Brisbane, the capital of Queensland, lying on the east coast of Australia, is subtropical oceanic, with very mild, relatively dry winters and hot, rainy summers.
Because of its location, in winter, the city is more sheltered from the cold than the southern cities (Perth, Melbourne, Sydney), and also from wind and rain. In addition, it is also sheltered from heatwaves coming from the desert, since the ocean currents prevail in summer. However, in summer, it can sometimes be affected by tropical cyclones, or at least by their remains, which in any case are able to bring heavy rains.
Being in the Southern Hemisphere, like the rest of Australia, it has reversed seasons in comparison with Europe or North America.
Here are the average temperatures.

Winter, from June to August, is very mild: the average daytime temperatures are about 20 °C (68 °F). At night, it can sometimes be cold, in fact, the temperature can drop to around 3/5 °C (37/41 °F), but during the day, it remains mild. There are many sunny days, and the rains are quite rare.

Spring, in September and October, is pleasantly warm, but the rains start to increase.

Summer is long, going from November to March, and it's hot and muggy, but tempered by sea breezes, which regularly blow, especially in the afternoon. The weather is often good, but thunderstorms can break out quite often, sometimes accompanied by hail and wind gusts. In La Niña years, the rains may be particularly abundant, as happened in January 2011, when the Brisbane River flooded the city.
Every now and then, a tropical cyclone can reach the city, although this rarely happens because cyclones usually pass over the area more to the north, beyond the Tropic. Sometimes, cyclones can pass over the ocean at some distance, causing storm surges that can reach the coast.

Autumn, in April and May, is pleasantly warm, and it is quite rainy, although the rains are generally less intense than the summer thunderstorms. In May, sometimes at night, it can get a little cold, with minimum temperatures below 10 °C (50 °F).

The sea near Brisbane is quite warm to swim in from December to April, when the water temperature is around 24/26 °C (75/79 °F), while in winter, from July to September, it is cool, about 21 °C (70 °F), but after all, it's not impossible. So, if you go in the Southern Hemisphere winter, maybe in July and August, on a fine day, you can even try a swim in the sea.
The Goald Coast to the south and the Sunshine Coast to the north of the city are popular with surfers, while the city is located in a bay (the Moreton Bay) which is more sheltered from waves.
Here are the average sea temperatures.

Best Time


Given that it has a good climate, you can visit Brisbane all year round. However, you can choose winter and early spring, ie from June to September, since it is the driest period of the year. October is a bit more rainy, but it is pleasantly warm, without excesses. Summer is hot and muggy, but the heat is generally bearable, and it's a good period for swimming and sunbathing; sometimes, however, there can be severe thunderstorms, and even a cyclone can approach the city.
