Summary
Forecast for the next 7 days according to Reefranger:
Today at Blenheim Beach, conditions may not be ideal for snorkeling or diving, with swell at 1.8 meters and strong winds at 37.4 km/h from the NE; expect surface chop. A 3mm wetsuit should suffice with the ocean at 22.3°C. Midweek, particularly Wednesday, presents the most favorable conditions with lower swells at 1.3 meters and winds dropping to 27.4 km/h from the S, offering calmer waters for diving and snorkeling. Caution is advised towards the end of the week as swell height increases to 2.0 meters on Thursday, making it less suitable for diving adventures.

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.
