The Lowdown
Alright folks, Rusty here. Let's chew the fat on what Leca's got lined up for the next couple of weeks.
We're starting off slow, real slow. The first few days are a total washout with poor conditions and bugger-all energy. There's a dry spell until we hit the morning of Thursday, September 3rd. That morning shows a hint of hope with glassy water, but the swell is a paltry 2ft from the NW with a short 8-second period and weak energy. It's rideable, but just.
The real fun, the one you want to be awake for, starts to build on the morning of Saturday, September 5th. The wind swings offshore from the ENE at 15 mph, cleaning up a 3ft NW swell. The energy is picking up (145), and it's looking like a proper little session. The water temp is about average for this time of year, so no worries there.
The standout session in this whole 16-day window is the morning of Tuesday, September 8th. We're looking at a 4ft swell from the WNW with a solid 10-second period, and the wind is glassy. That's a recipe for clean, fun waves. The combined energy is a solid 296, so there's some grunt behind it. This is the one to mark on the calendar. The break is consistent, so you won't be sitting there long, but it's a beginner-friendly spot, so expect company – crowds are often here.
After that, it gets a bit sketchy again. The morning of Sunday, September 13th sees a bump in size to 6ft from the NW with a short 7-second period, but the wind is cross-off from the NNE, keeping it relatively clean. The energy is up there (376), but that short period means it'll be a bit of a mess and less organized. This one is pushing into "too big for beginners" territory.
The following week is a mix of small, clean windows. The mornings of Monday, September 14th and Tuesday, September 15th both have offshore winds from the ENE, but the swell is small and weak. The morning of Wednesday, September 16th has a glassy 3ft swell from the W with a good 11-second period (218 energy), which is worth a look but nothing to get excited about. The final day, Thursday, September 17th, also has glassy conditions in the morning, but the swell is still small.
In short, the first week is a dud until the 5th, and then the 8th is your best shot. The second week is a bit of a lottery, with small windows of quality but nothing that screams "all-time." For a spot like Leca, which is fairly consistent, we'll see if the forecasts dial in something better as we get closer.
Rusty, signing off.

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.
