The Lowdown
Alright, Rusty here, checking in with a look at the surf for the next couple of weeks.
Honestly, it’s a pretty quiet stretch ahead. We’re looking at a long run of small, messy conditions that just aren’t worth paddling out for. From now through to the end of August, the swell is tiny and the wind is mostly onshore or cross-shore, making for a lot of choppy, bumpy water. We’re talking a solid 12 days of nothing doing. You’ll see the combined energy hanging around in the low two-digit range, like 27 or 48, which is just weak.
The first real glimmer of something halfway decent doesn’t show up until Monday the 31st of August at 47th Street. The swell finally bumps up a bit to around 4ft–4ft from the E, with a short period of just 6 seconds. The combined energy jumps to 112-168, which is at least moderate. The winds go clean offshore in the afternoon, so the waves will have some shape to them. It’s surfable, but still pretty ordinary.
But the standout, the one to actually circle on the calendar, is Tuesday the 1st of September. It’s still small at 47th Street, with the swell sitting at 5ft from the E and an 8-second period. What makes it special is the wind. It’s forecast to go glassy in the morning. Glassy conditions are a rare treat here, and that clean surface will make those waist-to-chest high waves look a lot better than they are. The combined energy hits 332, which is the strongest we’ll see in the whole period. This is far out though, so keep an eye on the forecasts, but as it stands, that Tuesday morning is the best shot we’ve got for a proper, clean session. The afternoon still looks clean with a light offshore, but the swell drops a touch.
That’s about it. A long dry spell, then a brief window of interest right at the start of September. Keep the board waxed and hope the long-range forecast holds.
Rusty.

Information about the 47th Street Surf forecast
The above surf forecast table for 47th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 47th Street can be found by selecting the local surf guide option on the grey menu. Our 47th Street 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 (47th Street) 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 47th Street 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.
