The Lowdown
Right, Rusty here again. Same story, different numbers.
This 16-day stretch for 48th Street is a tough one. Mostly tiny, weak, and messy. There’s a long gap of nothing really worth paddling out for, from the start right through to around the third week of August.
The water’s feeling a touch warmer than usual for this time of year, about 78° on that first Monday – a bit out of the ordinary but nothing wild.
Through the first week, from the 10th to the 16th, swell heights barely hit 2 ft, with periods mostly around 4 to 7 seconds. Energy readings are weak, in the 10 to 48 range. Winds are all over the place, but with barely any swell, even a glassy calm afternoon on the 14th with waves around 2 ft doesn’t do much.
On the 17th of August (Monday), energy jumps to 125 in the morning and 184 in the afternoon with a 4 ft south swell and 6-second period. The afternoon wind turns cross-off and clean, making this the best chance for a few weak, racy walls. Still, it’s a beach/jetty setup with short period – don’t expect perfection.
The 19th of August stands out for quality: a 2 ft swell from the southeast with a long 12-second period, giving moderate energy (119-145). That’s the kind of groundswell that wraps better around the jetty, but at this size it’s still small, and the afternoon onshore wind makes it choppy. Expect company – crowds are often at 48th Street.
Biggest swell hits on the 21st of August: 5 ft from the SSW with 6-second period and a strong energy reading of 281. The morning has clean cross-off winds, but over 5 ft with short period is only for experienced surfers looking for a close-out challenge.
The 22nd of August (Saturday) is the first day rated “surfable” – 2 ft, light cross-off, 52 energy. Hardly a standout, but the only day after the 17th that’s not rated poor.
Summary: your best shot is the afternoon of the 17th for the most manageable clean swell, the morning of the 21st for size (experts only), or the 19th for a long-period groundswell that’s tiny but has the best shape. Otherwise, it’s a quiet, flat run.
Rusty.

Information about the 48th Street Surf forecast
The above surf forecast table for 48th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 48th Street can be found by selecting the local surf guide option on the grey menu. Our 48th 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 (48th 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 48th 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.
