The Lowdown
Alright folks, Rusty here. Let’s break down what Lymans is showing for the next couple of weeks. I’ll be honest, it’s a lean stretch overall. This reef and point spot works best on a WNW swell, but the models are feeding it mostly small, weak SSW energy. There’s a lot of flat, choppy, or blown-out days in here.
The bright spot that’s closest is Tuesday morning, August 25th. The ocean goes glassy, with the wind completely calm. There’s a 0.6m (2ft) groundswell from the SSW with a long 16-second period. The wave energy is moderate (282) and with zero wind, it’ll be about as clean as it gets. It’s small, but for a beginner-friendly spot, that’s a solid chance. Later on, Monday afternoon, September 7th, the swell picks up to 0.7m (2ft) from the same SSW direction, still with a nice 14-second period, but the wind turns light cross-offshore. That'll clean the faces right up. The combined energy is 270, which is moderate. This is another one to circle.
If you’re willing to gamble on the long-range, Tuesday morning, September 1st has the highest energy pulse of the whole run at 462. The swell is 0.8m (3ft) from the SSW with an exceptional 18-second period – that’s a very long period groundswell – and the wind is straight offshore. This is the one to dream on, but remember it's more than a week away, so it’s a promising signal, not a guarantee. Lymans being a point setup should handle that long period beautifully, though.
The rest of the time? Tough sledding. Long gaps of flatness or onshore chop. Water temp is about 28°C (82°F), running a touch warmer than average, so at least it feels good.
Into the second week, from September 2nd on, it’s tiny with periods dropping off. Wind is mostly onshore, making the ocean messy. By September 4th, you’ve got a near-gale at 55 km/h (34 mph) from the south – a total write-off. There’s a glassy moment on September 5th with a 0.6m (2ft) swell at 19 seconds, but it’s not enough to get excited about. A blank run like this isn’t unheard of for Lymans when the wind and swell windows just don’t align.
So, for the best surf: hit Tuesday August 25th for glassy, tiny waves. Next best is Monday September 7th afternoon for a touch more size with that clean cross-offshore breeze. The longshot to watch is Tuesday September 1st. Otherwise, the boards stay in the car.
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.
Lymans is 94 km (58 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
