Summary
Forecast for the next 7 days according to Reefranger:
Today’s conditions at Blenheim Beach feature a 1.6-meter swell from the SSE and a strong 33.1 km/h NE wind, creating surface chop which isn’t ideal for snorkelers or divers. Ocean temperatures are 20.1°C, so a 3mm wetsuit would be advisable. Waves increase to 2.5 meters by Wednesday, making the middle to later part of the week less suitable, especially with persistent wind. Tuesday seems the best for diving or snorkeling, with lower wind speeds and warmer waters. Keep an eye on conditions, as the swells and winds make early in the week the most promising for better visibility underwater.

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.
