Best Swimming Weather
- Air temperature: 25-32°C is ideal — warm enough to dry comfortably after swimming
- Wind: Light breeze keeps you cool on the beach; strong wind creates chop and currents
- UV: Apply waterproof SPF 50+ sunscreen 20 minutes before entering water
- Waves: Under 1m for casual swimming; bodysurf in 1-2m waves
Open Water Safety
- Never swim alone in open water
- Check for currents, rip tides, and water quality advisories
- Swim parallel to shore if caught in a rip current
- Cold water shock is real below 15°C — enter gradually
- Wear a bright swim cap for visibility
Pool vs Open Water Temperature
Heated pools are typically 27-29°C year-round. Open water temperatures vary dramatically by season and location. Always check current water temps before planning an open-water swim.
