The Lowdown
Alright, let’s break it down for Lymans in feet and miles. This is a reef and point set-up, so it handles swell better than a beach, but honestly, the next week and a half is looking pretty flat and quiet. There’s a big gap of nothing really surfable for the first several days, so don’t get your hopes up too early.
The water temp is sitting at 82°F, which is a touch warmer than normal for this time of year—nothing extreme, just a little extra warmth in the water.
The first spot that really catches my eye is actually a late bloomer. On the afternoon of September 1st, we’ve got a small but clean 2ft SSW groundswell with a very long 18-second period. That kind of period is prime for a point break like Lymans—it’ll wrap in nicely, with good shape and energy. The combined energy is moderate at 569, and the wind is glassy light from the WSW, so it’ll be clean. This is the standout window, but it’s still a bit marginal overall, so don’t expect perfection.
The next best window is around September 6th and 7th. The morning of the 6th sees 1ft SSW swell, 17-second period, with light cross-onshore wind from the SW. It’s not glassy, but the energy is moderate at 440. The afternoon of the 7th picks up a bit more—2ft SSW swell, 15-second period, but the wind swings NW and becomes a gentle cross-onshore, which messes with the surface a little. Combined energy is moderate at 546. Still, it’s the best of a quiet bunch.
Outside of those windows, most days are either too small, too choppy, or just plain flat. The period around August 28th to 31st is a dead zone with almost no swell. The first week of September has a few small pulses, but nothing consistent.
Overall, if you’re keen, target the afternoon of September 1st or the September 6th–7th window. It’s not a classic run, but for a reef and point, those long-period SSW swells could still offer a few fun ones.

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.
