The Lowdown

Right, I’ve had a look over the coming days at 13th Street. Gotta be straight with you – this is a tough forecast for this spot. The whole 16-day outlook is basically a waiting game, with only a fleeting window of interest right at the tail end.

We start from now and it’s a pretty grim run. From Friday the 14th of August all the way through to Thursday the 27th of August, we’re looking at a string of weak, onshore wind conditions with tiny swell. The waves are barely there, and when they are, the wind is junk. The combined swell energy is weak, bouncing around between values of 75 and 420 (weak to moderate), but the wind keeps it messy. It’s a long, quiet period.

Then, things finally change on Friday the 28th of August. A solid pulse of swell arrives. We see a jump in size to 7ft from the SSW, with a period of 14 seconds – that’s a decent groundswell with some push. The combined energy hits 1657, which is strong. This is a serious step up in power. The wind stays light and onshore though, which is a shame, keeping the conditions marginal. This kind of size at 13th Street, with a south-west angle, is strictly for advanced surfers only – it will be too big for beginners at over 5ft. The long period swell (14 seconds) will favour reefs and points over this beach break, but with the onshore wind, it’s likely to be a battle.

Saturday the 29th of August sees the swell drop back to 5ft but with a shorter period of 11 seconds, and the energy drops to 526 (moderate). The wind is still light and onshore. It’s still a step up from the flat spell, but nothing clean.

If you’re an experienced surfer and desperate for some juice, the morning of Friday the 28th is the only real call in this whole forecast, but keep your expectations in check with that wind. For anyone else, it’s a write-off.

Stay patient,
Rusty

Information about the 13th Street Surf forecast

The above surf forecast table for 13th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 13th Street can be found by selecting the local surf guide option on the grey menu. Our 13th 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 (13th 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 13th 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.
