The Lowdown
Alright, Rusty here. Let’s get into it.
Honestly, mate, the next couple of weeks at Lymans are looking pretty grim. We’ve got a real dry spell on our hands. The water is sitting at 82°, which is a touch warmer than normal for this time of year, nice for a paddle but not much else.
We kick off on Friday the 14th of August. The morning is glassy, dead calm, with a tiny 1-foot WNW swell and a combined energy of just 25. It’s clean but too small to really do anything. The afternoon sees a shift to a 4-foot N swell, but the period is a short 7 seconds, meaning weak, messy waves. The energy jumps to 134, but it’s disorganised. Saturday the 15th is a write-off with rain and cross-onshore winds messing up a small 4-foot NNE swell. Sunday the 16th gets worse with a stronger 12 mph cross-onshore wind and a tiny 1-foot swell. This pattern of poor conditions and weak swell holds all the way through the following week.
There’s a glimmer from Tuesday the 25th of August. The morning shows a 2-foot SSW groundswell with a period of 16 seconds, combined energy at 280, and a light offshore wind. It’s still marginal surf, but that long period will hold some shape, and the wind is clean. The best chance in the whole run looks like Wednesday the 27th of August. Morning shows a 3-foot SSW swell, period 14 seconds, combined energy hitting 290, with a light offshore wind. It’s still only marginal, but for this stretch, it’s the standout. That swell direction is right in the optimum WNW window for Lymans, so it should wrap in nicely. The conditions are still borderline, but if you’re keen, that’s the session to aim for through the middle of the week.
After that, it drops back to tiny, weak swell through the end of the month. All in all, a pretty flat and quiet period for Lymans. Keep an eye on the forecasts, but don’t hold your breath.
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.
