Summary

Forecast for the next 7 days according to Reefranger:

Today at The Arches Marine Sanctuary, conditions are challenging for snorkeling and diving with a swell height of 2.8 meters and strong winds at 35.3 km/h from the SSW, creating choppy waters. Ocean temperatures are brisk at 16.8°C, so a 5mm wetsuit is recommended. Conditions worsen over the weekend, with swells peaking at 5.6 meters and winds exceeding 50 km/h on Sunday, making it unsafe. However, Tuesday looks promising with a significant drop in winds to 15.5 km/h and a moderate swell of 3.9 meters, offering a potentially good day for experienced divers to explore the sanctuary.

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.
