The Lowdown
Alright, let’s get into it. To be straight with you, the next couple of weeks are looking pretty grim for a proper paddle. We’re looking at a long stretch of small, weak surf, and honestly, for the first week and a half, it’s mostly a flat spell.
We’ve got a little bump of energy trying to show up on Monday the 17th, but it’s nothing to write home about. The swell’s coming from the SSE at around 3ft with a short 6-second period. It’s surfable, but very ordinary. That morning, we’ve got a light offshore wind, which is a saving grace, keeping things clean. But by the afternoon, it’s already gone soft. Then we drop right back into the doldrums for days. There’s a gap from Tuesday the 18th right through to the following Friday, with barely a ripple over knee-high.
Now, I know this is the tough part to hear for a surfer, but the numbers are what they are. The wave energy we’re seeing is weak, with values mostly sitting in the tens and single digits. Even the better days aren’t cracking 100. It’s just a flat, lifeless ocean out there.
The water is a touch warmer than normal for this time of year, about 3° warmer, which is nice but won’t make the waves any bigger.
Let’s talk about the only real glimmer of hope. Around Sunday the 30th, things might finally start to perk up. We’re seeing a bit more energy on the horizon, with the combined swell energy climbing into the 180-199 range. The swell direction is ESE, and it looks like we might get some clean, rideable waves in the 4ft to 5ft range. The wind for that Sunday afternoon looks like it might go offshore, which would be a huge plus. This is the standout, but it’s over a week and a half away, so treat it as promising, not guaranteed.
Before that, there’s some more energy showing around the 27th and 29th, but the winds are all over the place – cross-shore, cross-onshore – and it’s just not going to be clean.
Honestly, for the next week and a half, this is looking more like a kiteboarding spot than a surf spot. There’s just not enough push or shape for us. My advice? Don’t sell your board, but don’t get your hopes up for the next ten days. Keep your eye on that last weekend of the month.
Rusty, signing off.

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 120th 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.
