I probably should have mentioned, watch the winds and follow the synoptic weather charts when travelling most of W.A.
A high pressure system setting up in the central Bight area is a classic Summer weather pattern.
When this happens, you'll get stinking hot Northerly winds from the interior right over W.A. and the place roasts.
Those hot Northerlies are best avoided by laying up for a day or two somewhere, preferably near the coast.
Travelling in hot northerlies means your vehicle runs extremely hot, you risk tyre damage, and your fuel consumption will rocket.
The worst Summer feature of W.A. is the coastal trough. This is a slow-moving long area of low pressure that stretches North to South over W.A.
A trough will commence to form near the West Coast under summery conditions, and it then moves slowly across the state from West to East.
In doing so, it produces sticky, windless humidity that you get little relief from.
A West coast trough can be very slow-moving and can take a week or more to reach the S.A. border.
When this happens, the only relief from the heat and humidity you'll get, is right on the coast.
