The Lowdown
Alright, Rusty here. Let’s have a look at what Lymans is serving up for the next couple of weeks.
Honestly, the start is flat as a pancake. From Friday the 28th of August right through to the morning of Monday the 7th of September, there’s almost nothing worth paddling out for. Wind’s all wrong, tiny waves. The water temp is about 82°F, which is a bit above what’s normal for this time of year.
Then the afternoon of Monday the 7th of September finally shows some life. We’re looking at a 3ft swell from the SSW with an 18-second period—long period groundswell that brings real shape and energy. The wind goes dead calm, glassy. The combined energy reading hits 573—that’s strong. This is your absolute best window. The swell direction isn’t perfect for the spot (WNW is the magic number for Lymans), but with glassy conditions and this much push, there’ll be proper waves off the point. Expect some company.
Tuesday the 8th of September backs it up. Afternoon has 3ft from the SSW, 15-second period, and again glassy conditions. Energy is still high at 532. A little bigger, but still plenty manageable for a good session.
After Wednesday the 9th, things go quiet again. The second week has tiny, glassy moments—like the afternoon of Thursday the 10th—but with only 1ft and low energy, it’s more for a quiet cruise on the point. The long-period swells in that second week really need that point setup to work.
Bottom line: mark your calendar for Monday and Tuesday afternoons in that first week of September. That’s the only real action.
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.
