Summary
Forecast for the next 7 days according to Reefranger:
Today at Portsea Pier, the conditions are favorable for snorkeling and diving, with a mild swell of 0.9 meters and gentle northeast winds at 14.4 km/h. Ocean temperature is 18.1°C, suitable for a 3mm wetsuit. However, the weekend will see deteriorating conditions, with rising swell heights up to 1.1 meters and stronger winds, particularly on Sunday with wind speeds reaching 35.6 km/h, creating challenging surface chop. By midweek, higher swells of up to 2.6 meters suggest avoiding underwater activities. For a safe and enjoyable experience, today and possibly Saturday are your best bets.

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.
