Best Tide State to Fish Thompson Beach (Adelaide Plains crab flats)

The order of importance is tide, then wind, then clarity, and nothing else comes close. The bigger the low, the more flat there is to walk, and the standard program is to be on the sand at the bottom of the tide and working the flood back toward the car park. A dodge tide is a day to stay home, because a flat that does not drain is a flat you cannot rake. Wind is the reason most planned trips get called off, because nothing on the bottom shows through a chopped surface. Water clarity and warmth drive the activity — a hot, sunny, still day has the crabs moving, and the peak of the raking is late summer and early autumn on the warmest water. An overcast, windless day is the sleeper option, since the glare drops away and the crabs are still there. Winter thins the blue swimmers out and the sand crabs fill the gap from about May to September.

What Anglers Target Here
