The Lowdown
Alright folks, Rusty here. Let's have a look at what 48th Street has on offer for the next couple of weeks.
To be brutally honest, the first week is a write-off. You’re looking at a whole lot of nothing from Saturday the 18th right through until Tuesday morning the 22nd. Small, weak, and messy. Not worth paddling out for.
Things finally start to look interesting on Wednesday the 22nd. The morning kicks off with a 5ft southerly swell, clean winds from the west-southwest, and the energy is starting to build (264). It’s the Wednesday afternoon that’s the real standout though. The swell pushes up to 7ft from the south, with a period of 8 seconds, and the wind goes glassy offshore from the west at just 3 mph. The wave energy is pumping (801). This is your window for clean, solid, powerful waves. It will be a bit much for the beginners, but for anyone intermediate and up, get on it.
Thursday the 23rd and Friday the 24th are a step back, with messy cross-onshore winds and smaller, weaker swell. Nothing to get excited about.
The next real window opens up on Tuesday the 29th of July. The morning shows a 7ft easterly-northeasterly swell with a clean cross-offshore breeze from the south-southwest. The energy is strong (421). The afternoon holds similar, with the swell building to 7ft (456). This is solid, clean, and powerful, but at this size, it’s strictly for the experienced crew. The water is a touch warmer than normal for this time of year at 77°.
Wednesday the 30th of July continues the fun. Morning has a 6ft swell from the same direction, with a light north-northwest cross-offshore breeze. But the afternoon goes full glassy, with the easterly-southeasterly wind dropping to nothing. That’s proper clean conditions. The energy is still strong (295).
Thursday the 31st of July morning is another glassy gem, with a 6ft easterly-northeasterly swell and no wind. The energy is solid (306). The afternoon turns choppy, so get your session in early.
After that, it’s all downhill again into the first week of August, with onshore winds and fading swell. The forecast is less certain that far out, but the early signs are that the run of good surf is over.
The real standouts here are Wednesday afternoon the 22nd of July for the biggest, cleanest energy, and the glassy sessions on Wednesday the 30th and Thursday the 31st of July for those perfect, clean conditions. The crowds are a regular thing at 48th Street, so be prepared for company.
Rusty.

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.
