The Lowdown
Right, let’s have a look at what’s coming up for Lymans.
Mate, to be honest, the 16-day window is a bit of a mixed bag. There’s a lot of small, messy surf in the first week, and only a few windows where things might clean up. The standout period is definitely the second half of the month, with a few days that could be fun if you’re patient.
The first real surf worth mentioning is on Friday morning, July 17th. We’ve got a 3ft swell from the WNW, which is the optimum direction for this reef and point. The period is a solid 14 seconds, so there’s some real groundswell energy in the water (combined energy of 382). The wind is a light cross-on from the SW, so it’s not perfect, but it’s rideable. It’s a beginner-friendly break, so that’s fine.
The end of the first week and into the second week is a bit of a write-off. We’re looking at a lot of 1ft to 2ft swell with poor conditions and funky directions. Saturday and Sunday, July 25th and 26th, are the real standouts. Saturday morning, July 25th, we’ll see a 4ft swell from the SSW, with a 19-second period. That’s very long period groundswell, and for a point break like Lymans, that’s perfect. The combined energy is a decent 1146, and the wind is a light cross-on from the SSW. It’s marginal surf forecast, but with that period and direction, it’ll be a lot better than the numbers suggest. The crowd is *sometimes* an issue, so you might have a few others out there.
Sunday morning, July 26th, is similar: 4ft from the SSW, 16-second period, with a light cross-shore wind from the SSW. The combined energy is 866, and it’s another marginal forecast, but again, the quality of the swell should make it worth it. The wind is almost glassy, so it’ll be clean.
The 24th of July afternoon also has a bit of a pulse (3ft, 21-second period, combined energy 1034), but the wind is a light cross-on, so it’s not as clean as the weekend.
To sum it up: The best surf on offer is Saturday and Sunday, July 25th and 26th. The swell is a clean 4ft from the SSW, with very long periods, and light winds. It’s not huge, but it’ll be quality. The rest of the week is small or wonky. Don’t expect much during the first week – it’s mostly small, onshore slop.

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.
