READING THE SEA…
Is it warm enough to swim at Perth?
At 17.8°C the water is cool — refreshing rather than warm — fine for a swim, chilly on entry. Sea temperature lags the seasons, so the warmest water at Perthusually comes a month or two after the hottest air, and a cold current or a spell of offshore wind can drop it sharply within a day. This is the surface layer; it's cooler a few metres down.
