Eyeball surf reportRecent Eyeball Surf Reports for Nelson - Tasman Bay

  1. Overhead clean set waves with light wnds sounds ideal but there was a very strong sidehore current and a lot of the surf was dumpy. Just a handful of surfers out and having short sessions. Ruby Bay was better shape and smaller but the road was closed a long way short of the campground so nobody was surfing the point.

    Rabbit Island, 8 km away
  2. Wednesday afternoon offered mostly shoulder-high set waves though it was still head-high just as we paddled out at 1pm. The easterly stayed the right side of offshore so although it was on the smaller side, it was ok. Mostly cloudy with brief drizzle and the odd sunny spell.

    Wharariki Beach, 98 km away

Information about the Tahunanui Beach Surf forecast

The above surf forecast table for Tahunanui Beach provides essential information for determining whether the surfing conditions will be good over the next 12 days. A general guide to surfing at Tahunanui Beach can be found by selecting the local surf guide option on the grey menu. Our Tahunanui Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Tahunanui Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Tahunanui Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
