Summary

Forecast for the next 7 days according to Reefranger:

Today at The Arches Marine Sanctuary, the ocean temperature is a cool 16.9°C, suggesting the need for at least a 5mm wetsuit for comfort. Swell heights of 2.5 meters with northern winds at 17.6 km/h may cause some surface chop, making conditions less than ideal. The best day for snorkeling or diving appears to be Friday, with slightly reduced swell and manageable wind speeds. Avoid the weekend, especially Saturday and Sunday, due to higher swell heights and strong southern winds reaching over 26 km/h, which could create challenging conditions and reduce underwater visibility.

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.
