The first month of winter, June, was second coldest on record and rainfall was 32% below average in Western Australia as a whole (BoM). At the Vasse River site however, rainfall has been higher than average for 2021. It's fair to say it's been cold and wet down this way!
The BoM outlook for July to September indicates that rainfall is likely to be neutral or below average (less than 60% chance of exceeding median rainfall) across the south west.
