Water Temperature in Exmouth: Daily Trends, Historical Records, and Forecast

✅ Water at this temperature is very warm and feels almost tropical. Swimming is comfortable for most people, even for long periods, with no sensation of cold. These conditions are ideal for relaxed swimming, floating, and water play, especially for families and casual swimmers. However, during very hot weather, the water may feel less refreshing, and short breaks are often welcome.

It’s important to note that these swimming tips and recommendations apply only in settled weather. When air temperatures drop below 20°C — and sometimes even below 25°C — swimming can feel uncomfortable, even when water temperatures are relatively high.

Autumn stays warm at around 24–27°C, while winter brings only a slight cool-down to roughly 21–23°C. Spring warms quickly again, usually sitting between 23–26°C as air temperatures rise and the dry season sets in.
