The Lowdown
Alright folks, Rusty here again, giving you the same story but in feet and miles. Fenway Beach is lookin’ pretty quiet through the next couple of weeks, so don’t get your hopes up too early. There’s a long stretch of flat, weak, or messy conditions before a late surge of solid energy.
The water temp is around 70°F, which is just a touch below the usual average for this time of year – nothin’ unusual.
The first chance of a wave comes on Tuesday morning, August 18th. We’ve got a small 3ft swell from the SSE, period of 7 seconds, and a light N wind blowin’ offshore. That’ll clean things up, but the energy is weak (87). It’s a rideable wave for a beginner spot, but nothin’ to get excited about. That window closes fast, and from Wednesday the 19th right through the rest of the month, it’s a long, flat spell. Swell drops to 2ft or less, with cross-onshore winds, choppy surface, and the combined energy rarely gets above 99. For a spot that’s fairly exposed to swell, it’s a frustrating run of small, poor surf.
The real standout is a long way off, so mark your calendar. The best bet rolls in on Wednesday morning, August 26th. We’ve got a solid 5ft swell from the S, period of 8 seconds, and a clean offshore breeze from the ENE. The combined energy jumps to 318 – moderate, solid power. The wind is light and offshore, so Fenway Beach will be clean and lined up. The direction is straight from the south, which works well for this breakwater setup. The only catch: crowds can sometimes show up here, so get in early.
That window is short. By Thursday morning the 27th, the swell drops to 2ft and while the period goes to 12 seconds, a strong cross-shore wind from the E at 15 mph chops it up. There’s a bit more size and energy on Friday morning the 28th (4ft, SE, 13-second period, combined energy 529) but the wind is cranking at 15 mph from the ENE. It’s clean-ish, but that energy is a bit wild for a beginner spot. After that, it all fades again into the first few days of September with tiny, weak swell.
So, bottom line: the first week and a half is a flat, glassy dud. The one clear standout is Wednesday morning, August 26th. Don’t miss it if you’re keen.

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.
