The Lowdown
Alright, let’s get into it.
First up, the long-range picture. The next couple of weeks are going to test your patience if you’re looking for a proper surf. There’s a lot of small, weak, and sloppy stuff on the menu for the first week and a half, with hardly any real push. Most days are going to be a paddle for nothing, and I’m not afraid to say it. We’re looking at a serious lull, with only a few brief windows where it turns on.
The best bet in this whole stretch is actually the morning of the 25th of August. We’ve got some clean conditions with no wind at all, and that little bump of SSE swell at 4ft is going to be the most organized we’ll see for a while. The energy is weak, only 131, so don’t expect any barrels, but if you’ve got a longboard and a good attitude, there will be a few fun ones to be had. It’s about as good as it gets in this run, and that’s saying something.
Before that, the 24th has a bit more size, pushing 4ft, but the wind is all over it, making it messy and poor. Not worth your time.
The real kicker is the morning of the 28th of August. The swell jumps up to 5ft from the S, and the energy reads a solid 516 – that’s the most powerful we see all forecast. The problem is, it’s coming with a cross-onshore wind, which will chop it up and ruin the shape. It’s got size but it’s going to be a battle. Not one for the faint-hearted, and definitely not one for beginners.
Things start to ease off after that, with a few small clean windows on the 30th and 31st, but they’re not offering much more than ankle-biters. The 1st of September looks like it might finally give us something a little more user-friendly, with some glassy afternoon conditions on 4ft SSE swell, but it’s still on the small side.
Here’s the deal: we’ve got one standout morning in the middle of next week, and then a promise of something more towards the end of the period. The rest is a grind. Stay patient, choose your sessions wisely, and maybe bring a book.

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