A subtropical climate means every month works. But each season rewards something different, and a good trip knows what it’s coming for.
Spring (September–November) · Our favourite
17–27°C, low humidity, spectacular jacaranda blooms. For pure weather, this is the sweet spot. Jacarandas turn New Farm and the river precincts purple in late October. The Glass House Mountains are dry enough for comfortable hiking. The water in Moreton Bay is warming up without yet being hot. Best for: city walks, island day trips, hinterland hiking, outdoor festivals (Brisbane Festival is in September).
Summer (December–February) · Water season
21–30°C, high humidity, afternoon storms common. Brisbane summers are hot but not extreme — afternoon storms roll through quickly and evenings are pleasant. January is peak school holidays, meaning Moreton Island and North Stradbroke get busier. Book reef and island tours 2–3 weeks ahead. Best for: beach days, snorkelling, river kayaking, Streets Beach at South Bank, outdoor dining.
Autumn (March–May) · Underrated
17–26°C, clear skies, lowest rainfall months. Autumn is quietly Brisbane’s most reliable season — warm, dry, low humidity, and crowds thinner than the Gold Coast or Cairns. Tamborine Mountain’s vintages have just been bottled, and the hinterland rainforest walks are at their most comfortable without summer humidity. Best for: wine touring, rainforest walks, city sightseeing.
Winter (June–August) · Whale watching peak
11–22°C, mild and dry, genuine t-shirt days. The humpback whale migration peaks July–September, and you can see whales from the shore at North Stradbroke Island’s Point Lookout. The dry winter air gives the Glass House Mountains their clearest visibility of the year — great for hinterland drives and lookouts. Nights are cool; pack a light jacket. Best for: whale watching, hinterland hikes, Story Bridge climbs, longer walks in Lamington.
