The Lowdown
Alright folks, Rusty here. Let’s have a look at what Leca has in store for us over the next couple of weeks.
Right off the bat, I’ve gotta be straight with you – the first several days are a write-off. We’ve got a stormy start with a risk of thunderstorms and a strong southerly wind at 30 km/h, cross-shore and lumpy, and the swell is a messy 5 ft from the WSW with a period of only 7 seconds. The combined swell energy is weak (222). Don’t even bother paddling out on Thursday.
Friday morning sees a jump in size to 7 ft from the W with a period of 10 seconds, and the energy picks up to moderate (951), but it’s still a marginal situation with questionable tide and a light cross-shore wind. It’s enough to get your hopes up but not enough for a good session. The rest of the weekend and into the start of next week is a flat, choppy mess with poor surf conditions and onshore winds. There’s a real gap in quality surf here from Thursday through to the following Wednesday.
The standout for the whole period, if you can wait, is Saturday the 5th of September. The morning is looking glassy with a light offshore wind from the SSW, and we’ll have a clean 4 ft swell from the NW with a nice long period of 12 seconds. That’s a proper groundswell, and with a combined energy of 372 (moderate), there’s some decent push. That long period will make for some nicely shaped waves at Leca, which is exposed to the west and handles the NW direction well. The water temp is about average for the time of year, so no need to worry about a wetsuit.
Sunday the 6th of September also has a decent morning with clean conditions – a light cross-offshore breeze and a 4 ft swell from the WNW, period of 10 seconds, and energy at 286 (moderate). It’s a solid option, but the Saturday morning is the clear winner.
After that, the surf drops away again, with a few small, clean scraps but nothing to get excited about until the second week, where we see a few glimmers around the 8th and 10th of September, but the winds are messy and the quality just isn’t there. The 5th of September is the one to circle on the calendar.
Rusty.

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