Recent heavy rainfall has driven October's strong market position, with Melbourne Olympic Park recording over 66 mm in the first 15 days of the month—already surpassing its long-term October average of roughly 64 mm—following a single-day total of 48.4 mm on October 1–2, the highest in 30 months. Bureau of Meteorology observations confirm this surge aligns with active frontal systems typical of spring in southeast Australia, when mean rainfall peaks in October and November. With mid-month totals elevated and additional showers possible before drier patterns return, trader consensus favors October exceeding November and December totals. Later months retain upside potential if sustained wet conditions develop, though current data and seasonal baselines limit their implied probabilities.
