Packing for Brisbane in December means dressing for 28°C days and 20°C evenings. A light cotton tee with a casual overshirt works well at 28°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 20°C, a modest 8°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 12 potential rainy days.
Local tip: Layers are more practical than a single heavy garment in Brisbane. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.

Why is Brisbane warm in December?
December in Brisbane reflects a mid-latitude climate pattern, with temperatures averaging 28°C by day and 20°C overnight. The city sits at 27 degrees south latitude, where the balance between solar radiation and heat loss drives conditions that are neither extreme nor static. The warm temperatures reflect a stable high-pressure pattern typical of the season, which suppresses cloud formation and concentrates solar energy at the surface. Day-to-night temperature variation of 8°C is moderate and manageable with a single mid-layer. Climate data: Open-Meteo ERA5 (1991–2020).
