Table - best surf conditions forecast for Westport-The Groins over the next 16 days.
The Lowdown
Westport-The Groins is a beach/jetty setup, sheltered from a lot of swell. It’s not gonna fire much over this 16-day stretch – mostly just poor conditions and small waves.
Thursday, August 27 starts tiny at 2ft with a fresh south offshore at 18 mph, but the energy is weak (157) and it’s rated poor. That sets the tone. For days, winds are cross or onshore, swell stays small, and the quality is garbage.
Sunday, August 30 afternoon shows a little life: 2ft from the SW, 16-second period, light cross-off wind, clean faces, energy (334) – but still “surfable but very ordinary.” Monday morning, August 31 is glassy, same 2ft (265), still ordinary. Not a classic.
Then a stormy mess hits Thursday, September 3 afternoon – 8ft of short-period junk with 25 mph cross-winds and energy at (1336). That’s kite territory, not paddle.
The real standout is Friday, September 4 afternoon: glassy, 5ft from the west, 10-second period (765), and “expect good surf.” That’s your best window. Friday morning is also good with 6ft and a light cross-off. Saturday morning, September 5 is glassy but small at 2ft, long 17-second period (464), clean.
Later, Wednesday, September 9 morning is glassy with 5ft from the WNW, 9-second period (597), clean again. And Thursday, September 10 morning is glassy but tiny at 2ft, long 16 seconds (424).
So the standout is Friday, September 4 afternoon – glassy, 5ft, clean. That’s the one. Crowds are possible here, but given the quality, they won’t be thick.
Water temp is 62°F, a touch warmer than usual for this time of year.
Big gaps between clean days. After that Friday glass, you wait until September 9 for another. The Groins just doesn’t line up often.

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 Westport-The Groins 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.
