Melbourne climate summary for the month of May 2013

Rainfall slightly 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 warmer than those usually experienced and averaged 9.8 °C (departure from normal 1.1 °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 18.1 °C (departure from normal 1.4 °C). Total rainfall for the month was 36.6 mm, this being slightly less than that usually recorded (normal 55.9 mm, percentage of normal received 65%).
