The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough one. The entire 16-day window is looking pretty bleak for 40th Street (breakwater). We’re talking about a long stretch of poor surf conditions with almost no let-up. The first real chance of anything even worth mentioning doesn’t show up until around the 15th of August, and even then it’s only a marginal call.

For the first week and a half, from the 2nd of August right through to the 14th, it’s a write-off. Every single session is flagged as "poor surf conditions." The swell is tiny, hovering around 1 ft to 2 ft, with combined energy readings mostly in the low to mid hundreds – that’s weak, gutless stuff. The wind is mostly onshore or cross-onshore, which is just going to mess up what little shape there is. The water is warm, but you won’t be doing much surfing.

There is a glimmer, and I mean a tiny glimmer, on the morning of the 15th of August. The forecast shows a 3 ft SSW swell, with a period of 16 seconds, and combined energy jumping to 473 – that’s moderate energy. The winds are light and onshore from the SW. It’s being called "marginal" rather than outright poor. Given the whole run of bad news, this is the only time you might get a few grovelly rides on a longboard, but don’t expect anything special. The afternoon of the 15th gets chopped up by a 12 mph cross-onshore wind, so that’s out.

The 16th and 17th of August then drop back into poor conditions with smaller swell and messy cross-onshore winds. So, to be honest, there’s no standout session here. The only day to even consider paddling out is the morning of the 15th, and even then, keep your expectations on the floor. The rest of the time, you’re better off doing something else.

Rusty.

Information about the 40th Street Surf forecast

The above surf forecast table for 40th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 40th Street can be found by selecting the local surf guide option on the grey menu. Our 40th 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 (40th 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 40th 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.
