Summary
Forecast for the next 7 days according to Reefranger:
Today, conditions at Portsea Pier aren’t favorable for snorkeling or diving due to high swells of 2.5 meters and strong winds reaching 54.4 km/h from the north, creating surface chop. Instead, consider midweek sessions where conditions improve. Tuesday and Wednesday are promising with a significant drop in swell height to 1.2-1.6 meters and moderate winds, providing a much calmer ocean surface. With ocean temperatures around 19.1°C, a 3mm wetsuit is advisable to maintain warmth during longer sessions in the water. Overall, targeting midweek offers the most favorable and comfortable conditions for underwater activities.

Diving Forecast
These are the reefranger ratings for the next 7 days. Ratings are available for the morning, low tide, and high tide. Tides are shown during the daytime (6am to 8pm). Ratings currently take into account Swell Height, Swell Direction, and location exposure based on swell direction versus the orientation of the site.
Scores reflect the ocean conditions in the 2 hours between 8am and 10am, and consider local heavy rainfall in the period prior.

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.
