Summary
Forecast for the next 7 days according to Reefranger:
Today, Blenheim Beach experiences challenging conditions with a 2.8-meter swell from the south and strong winds at 37.8 km/h. These conditions create significant surface chop, making snorkeling and diving difficult. The ocean temperature is 21.4°C, so a 3mm wetsuit is advisable for comfort. For the rest of the week, Thursday and Friday offer better opportunities with reduced swell heights of 1.9m and 2.1m, though winds remain high on Thursday. Saturday’s conditions improve further with a moderate wind speed of 27.4 km/h and manageable 2.0m swells, making it the best day for diving or snorkeling.

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.
