Melbourne climate summary for the month of January 2013

Rainfall much less than that usually received.

Located in the Central District at the head of Port Phillip Bay, Melbourne is Victoria's State Capital. Here, overnight minimum temperatures were much warmer than those usually experienced and averaged 16°C (departure from normal 1.7°C). That the overnight temperatures in Melbourne are higher than those in most surrounding localities is a consequence of the city being under the influence of the effect of urbanisation (cities are usually warmer than their rural surroundings, especially at night, because of heat stored in bricks and concrete and trapped between close-packed buildings). Daytime maximum temperatures were warmer than those usually experienced and averaged 27.3°C (departure from normal 1.4°C). Total rainfall for the month was 8 mm, this being much less than that usually recorded (normal 47.3 mm, percentage of normal received 17%).
