Alright, let's get into it. The Groyne is a reef setup that's exposed to the swell, but looking at the next 16 days, it's a real mixed bag with a lot of junky, wind-affected surf to sift through. The water temp is sitting at 69°F, which is a solid 2°F cooler than average for this time of year, so you'll feel that drop when you're sitting out there.
The first week is pretty grim. We kick off on Saturday, July 4th, with a weak, short-period 4ft SE swell getting chopped up by a 12 mph cross-on wind. The energy is weak (241), and the conditions are just poor. Sunday and Monday are even worse, with stronger winds hitting 19 mph and the swell jumping up to 8ft, but it's all messy cross-shore wind and rain showers. The energy picks up into the moderate range (643) on Monday afternoon, but it's not doing you any favors with that wind.
It's not until the morning of Wednesday, July 8th, that we see a glimmer of something. The swell is a solid 7ft with a much longer period of 12 seconds, and the energy is cranking up to 1058. That's a proper groundswell with some punch. The problem is the wind is still a cross-shore 16 mph, and the forecast calls it marginal. This is a setup for more experienced surfers only, as anything over 8ft is expert territory, and this is right on the edge. That long period will also mean the sets are a bit more spaced out, which can make the paddle out easier, but it might break a bit too straight across the reef.
The next real standout pops up later in the forecast. Look at the morning of Thursday, July 16th. We get a 7ft SSE swell with a 10-second period, and the energy is a massive 929. The wind is a clean cross-off from the SSW at 9 mph. That's a good sign. The conditions are still called marginal, but with that wind direction, it could clean up nicely. This is another one for the experienced crew given the size.
Then, we have a promising note on the last day, Sunday, July 19th. The morning shows a 3ft SE swell with a long 11-second period, the energy is 322, and the wind is a light 6 mph cross-off from the SSW. The forecast says "expect good surf conditions." This is the one that stands out for the wider range of surfers. The size is manageable, the wind is light, and the period is decent. But it's a long way out, so keep an eye on it.
Honestly, for the first 8 or 9 days, you're best off giving The Groyne a miss. The wind is just relentless. The two best windows are the morning of the 16th for the bigger, more powerful stuff, and the morning of the 19th for the cleaner, smaller waves. If you're a beginner, stay away from the 16th; that 7ft swell is going to be a handful. For the rest of the period, it's a lot of poor surf with strong cross-winds.

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