Summary
Forecast for the next 7 days according to Reefranger:
Today at Portsea Pier, conditions aren’t ideal for snorkeling or diving as winds are strong at 36 km/h and swells are moderate at 1.7 meters, generating surface chop. The ocean temperature is 20.8°C, so a 2-3mm wetsuit is advisable to stay comfortable. This weekend, Saturday and Sunday offer better conditions with lighter winds around 25-27 km/h and manageable swells between 1.5-1.6 meters, making it the best time to head out. Early next week, particularly Tuesday and Wednesday, should be avoided due to increasing swell heights over 2 meters and persistent strong winds.

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.
