Summary

Forecast for the next 7 days according to Reefranger:

Today’s conditions at The Arches Marine Sanctuary are not ideal for snorkeling or diving, with a swell height of 2.5 meters and wind speeds at 29.5 km/h creating surface chop that can be challenging. Ocean temperatures of 17°C suggest the need for a 5mm wetsuit to stay warm. Friday presents the best conditions for underwater enthusiasts, with reduced swells of 1.8 meters and lighter winds of 12.2 km/h, making for a more enjoyable and safe experience. Avoid the start of next week, particularly Tuesday, as the swell height reaches an unsafe 4.9 meters. Plan accordingly for a safe and pleasant excursion.

Model

Swell and wind impact diving suitability, but not all swells and winds are equal. A dive site may be protected from wind and swell by nearby geography. The model uses these exposure ratings to determine how much impact a wind and swell will have on the dive site, based on the origin of the winds or waves.
