The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, I’ll be straight with you – this 16-day stretch for Boston Bay is a tough one. The whole period is a battle with onshore winds that just won’t give up. We’re looking at a solid run of poor surf conditions, so don’t go getting your hopes up for anything clean or classic.
The pattern is pretty monotonous. From the get-go on Tuesday the 28th of July, we’ve got a persistent ESE wind blowing straight onshore, smashing up a weak, short-period swell. The water is a balmy 85°F with a water temp anomaly of 2°F, so it’s basically average for the time of year. The first few days offer nothing but poor surf with combined swell energy struggling to break triple digits, like a measly 68 on the 28th.
We finally see a bit of size pick up around Thursday the 30th, with the swell hitting 4ft to 6ft but the wind is still on it, and the energy starts climbing into the moderate range (183-347). By Friday the 31st, we’ve got 6ft of ESE swell coming in at a 9-second period, with combined energy hitting 593-607, but it’s all cross-onshore and choppy. Still, the surf report screams “poor.”
The only real standout, if you can call it that, comes on the morning of Saturday the 1st of August. The swell is still 6ft from the ESE with a 9-second period, and the combined energy is a solid 729. The wind is straight onshore, but for a brief moment, the forecast calls it “marginal” rather than “poor.” That’s the best we’ve got all week, and it’s barely a whisper.
The same story repeats through the rest of the first week and into the second. There’s a couple of days with a bit of size—like the morning of Friday the 7th of August with 8ft swell and energy of 1415, and the 11th of August with 8ft swell and a whopping 1813 of combined energy. But that’s big, onshore, and messy. For a beginner spot like Boston Bay, anything over 5ft is already too much, and over 8ft is expert-only territory. With the onshore wind, it’s just a washing machine. In fact, with that much wind and swell, the setup looks more interesting for kite surfing than paddle surfing.
Honestly, there’s no clean, glassy, or offshore window in the entire 16 days. I can’t give you a single break to run to. It’s a long, flat, and bumpy outlook. Keep your board in the car and check the forecast again in a few days – things can change.

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