The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up.
First off, the outlook for Lymans is a bit of a tough one. We’re looking at a long stretch of days where the surf is pretty ordinary. The water is sitting at 82° which is a touch warmer than the norm for this time of year, but that’s about the only highlight for a while.
The first couple of days, starting with Saturday afternoon, the 29th of August, there’s a tiny 1ft swell from the SW, but the real story is the 17-second period and that glassy wind from the WNW. It’s surfable, but very ordinary. The combined energy is weak (93). It’s a fickle start.
From there, we hit a real dry spell. Sunday the 30th through to Friday the 4th of September, the waves are small, the winds are messy, and the quality is just poor. You’ll be looking at a lot of 1.0ft to 2ft slop with short, weak periods. The guidance says poor surf conditions, and I’m not going to argue. It’s quiet.
Then, around Saturday the 5th of September, we get a little flicker. Saturday morning brings another glassy moment with a 1ft swell from the SSW, but the period jumps to 18 seconds. That long period combined with the glassy conditions will make for some clean, but very small waves. The combined energy is moderate (196). It’s not a standout, just a glimmer.
Sunday the 6th of September sees a bit more size, with a 4ft swell from the NNE on Sunday morning, but the wind is cross-shore at 9 mph, and the period is a short 6 seconds. The combined energy is moderate (205). The afternoons get a bit more interesting with a 2ft SSW swell packing a 19-second period. The wind is cross-offshore and the combined energy jumps to 413 (moderate). The conditions are clean, but it’s a marginal call.
The best of the bunch, and the one true standout in this whole 16-day window, looks to be Monday the 7th of September. The afternoon session sees a 3ft SSW swell with a 17-second period, and the wind is a light cross-on from the WSW at 3 mph. The combined energy is strong (667). It’s the biggest, cleanest, and most powerful looking swell of the period. Lymans is a reef and point break, so that long period, groundswell energy will wrap in nicely. The difficulty is beginner-friendly, so it’s not a heavy wave, but it’s the best we’ve got. The crowd factor is "sometimes", so there could be a few out, but for this spot, it’s worth it.
After that, from the 8th of September onwards, it drops back into the ordinary. There are a few more days with moderate energy and clean windows, like the 11th of September morning with a 2ft SSW swell and 16-second period, but the combined energy is moderate (328) and the conditions are just marginal. The 12th of September afternoon gets glassy again with a 2ft SSW swell, but the energy is only moderate (221).
So, to sum it up: don’t bother paddling out until the 7th of September. That Monday afternoon is your best bet with a solid, clean 3ft SSW groundswell. The rest of the window is a mix of small, weak, or messy conditions. It’s a long wait for one decent session.
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.
