THE Wimmera has experienced an unseasonably warm May, with more than two weeks of temperatures above the monthly average.
May 16 remains the hottest day for the month so far, but temperatures have remained steady above 20 degrees in Horsham, Warracknabeal and Nhill for almost two weeks.
Ararat has experienced only one day in the past week below 20 degrees, with Tuesday reaching a maximum of 19.1.
