Brisbane is experiencing a notably warmer and wetter spring in 2025, aligning with broader climate trends observed across south-eastern Australia. The Bureau of Meteorology's (BOM) spring outlook indicates above-average temperatures and increased rainfall for much of eastern Australia, including Queensland. This pattern is partly attributed to the negative phase of the Indian Ocean Dipole, which enhances moisture-laden air from the northwest, leading to wetter conditions.

In Brisbane, September has seen temperatures averaging higher than usual, with daytime highs reaching into the mid-20s°C. While specific daily maximums are not detailed in the provided data, the trend suggests a shift towards warmer early spring conditions.

Rainfall patterns are also shifting. BOM's outlook indicates a 70–80% chance of above-median rainfall across much of central and eastern Australia this spring. Queensland, in particular, is expected to receive above-average rainfall, especially in September and October. This increased precipitation is linked to the negative IOD phase, which is forecasted to peak in October, bringing moist tropical air over eastern Australia.

However, the increased rainfall does not eliminate climate-related risks. A recent national climate risk assessment warns that Brisbane could face up to 314 days of coastal flooding annually by 2050 under a 3°C global warming scenario. This projection underscores the need for proactive measures to address rising sea levels and their potential impact on infrastructure and communities.

As spring progresses, Brisbane residents can anticipate continued warm temperatures and increased rainfall. While these conditions may offer relief from previous dry periods, they also highlight the pressing need for climate resilience and adaptation strategies to mitigate the effects of a changing climate.
