When to go
This coast is most comfortable from late spring through autumn.
Best overall window
Warm beach weather, sea rising through 21°C to 27°C, and lighter typical winds around 15 km/h to 17 km/h in the calmest months
Outside that window
Cooler water near 15°C to 17°C, windier days often around 18 km/h to 21 km/h, and less reliable boat comfort
