Summary
Forecast for the next 7 days according to Reefranger:
Today at Blenheim Beach, conditions are challenging with a swell height of 2.2 meters and a strong NE wind at 32.8 km/h, creating choppy waters. Ocean temperatures are around 21°C, so a 3mm wetsuit is recommended. Better conditions are expected on Wednesday, with a reduced swell of 3.7 meters and moderate NNE winds at 22.7 km/h, making it one of the better days this week for diving. By Thursday, swell heights decrease further to 1.9 meters, although winds increase again, so watch for surface chop. Avoid Monday and Tuesday as high swells and strong winds persist.

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.
