April rainfall was below average throughout metropolitan Melbourne. Rainfall ranged from 55% of normal at Cerberus to 99% at Scoresby Research Institute. Most of the rain fell on the 6th and 7th, on the 22nd and at the end of the month, due to cold fronts that moved over the city. Melbourne City (Olympic Park) recorded 8 days with rain during April and a monthly total of 48.6 mm, almost half of which fell during the 24 hours to 9am on the 22nd. With a total of 89.0 mm, Ferny Creek in the Dandenong Ranges was the wettest location during the month in the greater Melbourne area. The highest daily total of 26.2 mm was also recorded at Ferny Creek.

For the month as a whole, maximum temperatures were very much above average across the metropolitan area. Most sites had maximum temperatures between 2.1 °C and 2.5 °C above the April average. At Melbourne City (Olympic Park), the warmest day saw 29.0 °C on the 5th; the highest maximum temperature recorded in the greater Melbourne area was 31.3 °C at Avalon Airport also recorded on the 5th.

For the month as a whole, minimum temperatures were very much above average at most sites across the metropolitan area. Melbourne City (Olympic Park) recorded 10 consecutive days (between 8th and 17th) with minimum temperatures above 10 °C, while the warmest night during the month (on the 28th) saw 19.8 °C.

Notes

The Monthly climate summary lists the main features of the weather in Melbourne using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 11 am on Monday 2 May 2016. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.

The ACORN-SAT dataset is used for temperature area averages.
