The Lowdown
Alright, listen up. We’re looking at a pretty quiet run for the next few weeks, but there’s one real window if you’re patient.
The first bit of the forecast is a total dud. From the 8th through the 14th, it’s all tiny surf, choppy wind, and poor conditions. You’re better off staying on the beach.
Now, Tuesday the 15th of September. That’s the one. Tuesday afternoon, the wind goes flat – glassy as it gets. We’ve got a clean 2ft swell from the SW, with a very long period of 19 seconds. That’s proper groundswell for the reef and point. The combined energy is moderate (361). The water is 82° here, which is about 2° warmer than usual for the time of year. Really nice. The crowds are “sometimes” an issue, but for a clean, glassy wave like this, that’s a minor thing. This is a spot for the more experienced surfer.
The days after that are mostly a letdown. Wednesday the 16th has 3ft from the SSW with an 18-second period, but the wind is onshore, so it’s messy. The energy is still moderate (426). Thursday the 17th is much the same. There’s a flash of glassy conditions on the 21st of September, but the swell is only 2ft and the period drops to 13 seconds – it’s weak.
The 18th, 19th, and 20th of September keep the swell around 2ft to 3ft, mostly from the SSW, with 15-second periods. The wind is mostly cross or onshore, so it’s rough.
The 23rd of September has a bit more push with 3ft from the SSW and energy of (537), but again, the wind is cross-on.
So, overall, it’s a long, quiet spell with one clear standout: that Tuesday the 15th of September afternoon. The rest is a waiting game.
Rusty.

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