Table - best surf conditions forecast for The groyne over the next 16 days.
The Lowdown
Right, let’s have a look at what’s on offer for The groyne. This is a reef setup, and it’s fairly consistent, so it can fire, but you’ve got to pick your moment. The water is sitting at 69°, which is pretty much what you’d expect for this time of year, nothing weird going on there.
Honestly, this 16-day stretch is a tough one. The first few days are a write-off. Monday the 20th and Tuesday the 21st are a mess – we’re looking at a solid 12 ft to 7 ft of easterly swell, but it’s getting hammered by fresh cross-onshore winds, making it lumpy and poor. The combined energy is high (2787 on Monday morning), but it’s just ugly. Wednesday the 22nd is a bit smaller at 6 ft, but still onshore and marginal.
The first real glimmer of hope comes on Thursday the 23rd. The swell drops to a clean 4 ft from the east, with a period of 8 seconds. The wind swings to a light cross-offshore from the SSW, and the forecast says clean conditions. The energy is a modest 203, but it’ll be the most fun surf of the week. It’s not huge, but it’ll be rideable and uncrowded if you’re lucky. That’s your best bet for the first week.
After that, it’s a bit of a rollercoaster. Friday the 24th gets messy again with a jump up to 5 ft and a short 6-second period, but the wind is cross-on. Saturday the 25th morning cleans up again with a cross-offshore breeze and 4 ft swell from the ESE, but the swell is small and the energy is low (228). Sunday the 26th and beyond, the swell drops right off. From the 27th of July all the way through to the 4th of August, we’re looking at tiny waves, mostly under 2 ft, and often with onshore or cross-shore winds. The energy figures are in the low double digits, barely a ripple. The 30th of July has a weird 20-second period on a tiny 0.7 ft swell, but it’s cross-onshore and lumpy, so no good.
So, the standout here is Thursday the 23rd. It’s not a classic, but it’s the only day where the conditions align for a decent paddle. The rest of the 16 days is a long, flat, or blown-out gap. No other options on the table.

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.
