The Lowdown
Alright, Rusty here. Let’s talk about what’s happening at 48th Street. This beach/jetty spot is fully exposed to the swell, but we are looking at a whole lot of nothing for a while.
Starting off on Monday the 17th, we’ve got a small 3ft S swell, but it’s a short-period 5-second windswell. A WNW breeze at 12 mph just messes it up. It’s weak and messy. The water temp is about normal for the time of year.
Tuesday through the rest of the week and into the next is just flat and poor. Tiny waves, wrong winds, and no real energy. You’re looking at a quiet spell from now all the way to the 28th.
Things start to stir on Friday the 28th. The swell bumps up to 5ft to 6ft from the ENE, but the period is still short (6 seconds), and the wind is cross-shore or onshore. The wave energy picks up to a moderate range, but the conditions are too choppy for a good surf. This setup looks more interesting for kite surfing than paddling.
The real standout is Saturday the 29th. The morning shows a 4ft SE groundswell with an 11-second period and strong energy. The winds are still a little bit cross-shore. But the afternoon is the golden window. The wind goes glassy, and you’re looking at 3ft from the ESE at 10 seconds. The wave energy is solid at 308, and with that clean, glassy surface, the waves will have some good shape. For a beach break, longer period swells like that can sometimes break a little too straight, but with how clean it’s looking, it should be worth the wait.
After that, it feels like it drops back off into poor conditions through Monday the 31st and Tuesday the 1st of September.
Don’t bother paddling out 'til later in the week. Mark that Saturday the 29th afternoon on your calendar. That’s the one.

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.
