Recent heavy rainfall across Melbourne, including a 48.4 mm deluge on October 2 that marked the wettest day in over two years, has elevated October's totals to 48.6 mm early in the month against a 65.7 mm climatological average. This active pattern, with additional showers and thunderstorms forecast through the weekend per Bureau of Meteorology guidance, supports October's 25.5% market-implied odds alongside August's finalized 66 mm total, which exceeded its long-term mean. November and December hold comparable probabilities near 26% due to their higher historical averages of 60–65 mm and typical spring-summer moisture influx, though model consensus on steering patterns and any late-year variability could shift the narrow margins as new observational data emerges.
