Summary
Forecast for the next 7 days according to Reefranger:
Today at Blenheim Beach, the swell is 1.9 meters from the NE and winds are quite strong at 37.4 km/h, causing surface chop, making diving and snorkeling challenging. Ocean temperatures are around 22.3°C, so a 3mm full wetsuit is advisable for comfort. The best conditions this week appear on Wednesday and Saturday, with swells dropping to 1.5-1.9 meters and winds decreasing to 27.4-26.6 km/h, offering calmer waters. Thursday and Friday feature higher swells at 2.1 meters and NE winds over 30 km/h, so consider avoiding snorkeling or diving on those days.

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.
