Summary
Forecast for the next 7 days according to Reefranger:
Today at Portsea Pier, conditions for snorkeling and diving are moderate with a swell height of 1.5m and somewhat strong southeast winds at 27.4 km/h, which may create surface chop. The ocean temperature is a mild 18.1°C; a 3mm wetsuit is advisable for comfort. Friday and Sunday are ideal days for snorkeling or diving, with low swell heights of 0.9m and gentler winds, ensuring calmer water conditions. However, avoid diving on Monday and Tuesday due to increased swell and strong northerly winds, which could result in turbulent conditions and reduced visibility.

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.
