Best Time for Coral Coast Highway: Perth to Exmouth

Sweet spot: May, June, July. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.

💡 Good to know

The highway remains possible, but extreme heat, bushfire, tropical-weather and long-distance driving conditions make live road, park and weather checks essential. Start early and change the day rather than drive tired or into a closure.
Autumn brings milder road-trip conditions. Marine tours and wildlife encounters are separately booked, seasonal and never part of the baseline itinerary.
Cooler days suit the long drive and park walks. Check every park alert and road condition; any whale, dolphin or wildflower sighting remains a possibility rather than a promise.
Spring can bring wildflowers and warmer coast days. Current heat, fire, road and park notices still control the plan, and marine conditions can cancel water activities.
