The Lowdown
Alright, ol’ Rusty here. Let’s have a look up and down the coast.
Honestly, looking at the next couple of weeks, there’s nothing to get genuinely fired up about at Westport-The Groins. The swell stays small, and the conditions are a bit of a mess for a good long stretch. The good news? Clean windows do appear, but the wave heights are very modest.
On Sunday morning, August 16th, we start off cloudy with a light cross-onshore breeze. Swell is a tiny 2 ft from the SW with a long period of 16 seconds – that’s a clean groundswell but lacking any real power. Water temp is 56°, which is feeling a bit colder than usual, about 3° below the norm. Combined energy is weak (313). Conditions look poor, flat and ripply – best to leave the board at home. The whole first week stays frustrating.
Tuesday morning, August 18th, a light WSW cross-off breeze makes things clean for a brief moment. Still only 2 ft and a long 15-second period from the SW. Combined energy is low (320). Surfable but very ordinary, meaning you’ll have to scratch for tiny waves.
On Wednesday morning, August 19th, we get a whisper of hope. The swell edges up just a notch to 3 ft from the west, period at 12 seconds. Winds are light and cross-off from the WSW, so it’s clean. Combined energy still moderate at 358. Still small, but if you’re itching, it’s the best of an average lot.
Thursday morning, August 20th gets a little bump in swell height to 4 ft from the WNW, but the period drops to a short, weak 9 seconds and it’s onshore. Combined energy is moderate (416). This one looks sloppy – more for a rock hop than a surf session.
Then we settle into a long run of days through the rest of August where the swell sits between 1 ft and 3 ft. The standout clean windows come on Friday, August 21st and Saturday, August 22nd. Light cross-off winds make for clean, rideable but small waves – 3 ft to 3 ft on the Friday morning (combined energy 269, moderate) and similar on Saturday morning (156, weak). If you’ve got a log, you could have some fun, but it’s not going to challenge anyone.
Saturday, August 29th, the afternoon shows a little life. South winds swing to light cross-off, with 3 ft from the WNW, 10-second period. Combined energy is moderate (389). Clean, small but surfable.
Finally, Sunday morning, August 30th brings a glassy early window with a light SSE breeze, 2 ft from the SW, 15-second period and combined energy at 268 (weak). Clean but flat.
Further out, Monday morning, August 31st sees flat, glassy conditions – 2 ft from the SW with a long period. Combined energy weak (268). Perfect conditions for a sunrise paddle, not a proper surf.
So, across the board, there’s no moment that screams “go now.” The best of the bunch is Wednesday morning, August 19th, when the swell hits 3 ft with clean conditions and moderate energy. It’s not big, but it’s the only morning that feels like a real session window.

Information about the Westport-The Groins Surf forecast
The above surf forecast table for Westport-The Groins provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Westport-The Groins can be found by selecting the local surf guide option on the grey menu.

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.
