The Lowdown
Alright, let’s have a look at what’s coming up for Lymans. To be straight with you, the next couple of weeks are a mixed bag – there’s no real size or power on offer for a while, but there’s a few windows of clean conditions that might get you out for a splash-around session. The water temp here is sitting about 82°F, which is a notch warmer than usual for this time of year – about 2°F above the long-term average, so not a shocker, but noticeable when you’re in the water.
The first few days are pretty grim. From Thursday afternoon the 27th right through to the end of August, it’s mostly tiny, weak swell with cross-onshore winds messing it up. Honestly, it’s not worth paddling out for. The combined wave energy is low – mostly under 100 – and the wave heights barely nudge above 2ft. There’s a brief moment Saturday afternoon the 29th when the wind goes glassy and the swell period hits 17 seconds, giving a bit of long-period groundswell energy at 1ft, but it’s so small and weak (energy at 93) it’s really just a wobbly ankle-snapper.
We then go through a long, flat, poor stretch. The first week of September is more of the same – tiny waves, poor wind, almost no energy. There’s another glassy window on Wednesday afternoon the 2nd, with a 1ft swell from the SSW at 11 seconds, but again, barely any push. You could sit on a foamie and feel something, but that’s about it. The combined energy is only 80 – basically nothing.
Then, something starts to stir around the 5th and 6th of September. By Sunday morning the 6th, we see a jump in energy – the combined swell energy hits 436 – which is solid moderate. Swell height is still only 3ft, but it’s coming from the SSW with a period of 18 seconds. That’s a very long-period groundswell. At a reef-and-point break like Lymans (which faces a bit more west-northwest in its optimum exposure), that long-period SSW energy might wrap in a bit, but it’ll be tricky. Long-period swells can break straight on beach breaks, but here at a point and reef setup, it could actually produce some nice, lined-up waves if the tide is right. Winds are light cross-onshore, but it's not clean enough to call it a standout yet.
The best on offer in the whole 16-day window shapes up for Tuesday afternoon the 8th of September. Swell height reaches 3ft from the SSW, period a nice 14 seconds, and the wind goes glassy – which is a big positive. The combined energy is a solid 516, so there’s some real grunt in the water. The wave comment says “expect good surf conditions,” and with offshore wind from the west-southwest, this should be the cleanest, most surfable session of the whole forecast. Keep in mind, Lymans picks up swell best from the WNW, but this SSW direction still puts some energy in the water – just not quite as lined up as it could be. Still, for a glassy 3ft wave with that period, it’s the pick of the lot.
The days following drop back down again – small and messy through the 9th and 10th, with only marginal conditions. By Friday the 11th, combined energy is back under 200, and it’s poor again.
If you’re chasing anything here, circle Tuesday September 8th afternoon. The rest is either flat, weak, or too messy to bother. Could be decent for a mellow cruiser session, but don’t expect any barrels.

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.
