The Lowdown
Alright, let’s take a look at what’s on offer. I gotta be straight with you – it’s a pretty flat and quiet run ahead for us at 48th Street. The next couple of weeks are looking like a real struggle to find anything worth paddling out for. We’ve got a long stretch of small, weak, and often wind-affected surf, so don’t get your hopes up.
The water here is sitting at 78°, which is a touch warmer than normal for this time of year – nothing crazy, just a bit of extra warmth in the water.
Right now, and for the first several days, it’s all tiny. We’re looking at waves mostly around 1 ft and the combined swell energy is pretty weak, nothing above 56 (low energy). The swell direction is hanging out of the SE, which is what this spot wants, but there’s just not enough size or power. You’ll get a glassy morning on Saturday the 22nd with a little 0.7 ft leftover, but it’s barely a ripple. Sunday the 23rd morning is glassy too with 2 ft, but the period is a super short 5 seconds – just not enough push.
Into the second week, things do tick up a notch in energy but still not in a way that’ll get you excited. By Thursday the 27th afternoon, we finally get a “surfable but ordinary” call with 2 ft from the SSE and clean cross-off wind – at least it’s clean, but it’s still small. That theme continues: small, clean, but unremarkable.
There is one period that pops a little more. On Monday the 31st of August, the combined swell energy jumps to 138 (moderate energy) with 2 ft SE swell, but the wind is howling out of the south at 19 mph – it’s cross-off so it’s clean, but it’s gonna be wild out there. That’s more of a kite-surfing breeze than a clean surf session, to be honest.
By the time we hit September 1st, we see the energy climb to 118 and 109 with some clean offshore wind from the WSW on Tuesday afternoon – that’s got potential for a few fun little waves if you’re desperate, but still small at 1 ft.
For this whole 16-day stretch, there’s no standout day. No real swell, no big period, no epic conditions. It’s one of those blank runs where you just gotta wait for the next system to come through. Keep an eye on the forecast – things can change.

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.
