The Lowdown
Alright, I’m Rusty, and I’m calling it like I see it. This 16-day forecast for 48th Street is a tough one. There’s a big dry spell at the start, so don’t get your hopes up early.
From Friday the 14th through the weekend, it’s flat and ugly. We’re looking at 0.6 to 3ft of weak, messy surf, with a mix of glassy conditions and onshore crud. The water is a touch warmer than normal at 79°, but that’s the only good news. The wave energy is pathetic, reading 12 to 24, so there’s just nothing to ride.
Monday the 17th shows a tiny improvement, but Tuesday the 18th afternoon is the first real sign of life. We get a 2ft SE swell with a 12-second period and glassy conditions. The energy climbs to 119, which is moderate, giving it some push. The wind is light and variable, keeping it clean. It’s surfable, but still very average.
The rest of that week is more of the same small, weak, and choppy stuff. A few cleaner moments pop up, like Wednesday the 23rd afternoon with a light offshore wind and a 2ft swell from the ENE, but the energy is still low. You’d be working hard for nothing.
The one standout, and the only time I’d tell you to grab your board, is on Thursday the 28th. The morning brings a 2ft SE groundswell with a 10-second period and a clean cross-offshore wind from the NNW. The energy is a solid 120, which is moderate and actually means something. The afternoon is even better, with the same swell but the energy jumping to 158 and cleaner wind from the WNW. That’s the best combination of the whole forecast. Remember, this is two weeks out, so it’s a promising signal, but not a guarantee.
Saturday the 29th goes back to a messy cross-shore chop. So, the bottom line: skip the first week and a half. The Thursday the 28th is your window for clean, fun, rideable waves. The rest is a bust.
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.
