The Lowdown
Hey, Rusty here. Let’s break down what’s happening at Lymans over the next couple weeks. It’s a slow start, no two ways about it. The first week is mostly small, weak, and messy. The only real bright spot is late in the first week, then it’s patchy again until the very end.
Water temp is around 82°, which is normal for the season – nothing out of the ordinary.
Monday 14 September starts with a tiny 1ft swell from the SW, long period of 23 seconds, but it’s poor with onshore wind and low energy. Tuesday 15 September bumps to 2ft, still onshore and marginal. Wednesday 16 September hits 3ft from the SSW with moderate energy, but cross-onshore breeze chops it up. Thursday 17 September drops back to 2–2ft, choppy. Friday 18 September is cross-shore and messy. Saturday 19 September similar.
The first real chance comes Monday 21 September afternoon. Swell holds at 3ft from the SSW, period a solid 13 seconds, and the wind goes glassy. Energy is moderate. The report says “expect good surf conditions” – this is your window. Small, clean, fun waves for a beginner-friendly reef and point. Lymans is fairly consistent and exposed to the WNW, and the SSW swell works well enough. Crowds are possible, so expect a few others.
After that, it fades. Tuesday 22 September afternoon has a tiny 0.7ft glassy wave with almost no energy. Wednesday 23 September afternoon offers 2ft, glassy again, but “ordinary conditions.” Friday 25 September afternoon has 2ft, glassy, still ordinary. Monday 28 September morning sees 2ft from the SW, long period of 18 seconds, moderate energy, but marginal. Tuesday 29 September morning brings 3ft from the SSW, period 16 seconds, solid energy – the best numbers of the whole run, but the comment is still marginal. Afternoon hits 3ft with strong energy, but cross-onshore wind spoils it.
The standout is Monday 21 September afternoon: glassy, clean, 3ft, good energy, and the only session that truly delivers. For the rest, it’s a lot of waiting.
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.
