The Lowdown
Alright, Rusty here, let's talk about what's on offer at Lymans.
The next couple of weeks are a bit of a mixed bag. We've got a run of days coming up that are pretty lackluster to start with, but things are looking up towards the end. There’s a decent window in the middle of the second week, but overall, you're going to need patience.
We're starting off with small, clean conditions, but the swell just doesn't have the power. Sunday the 13th and Monday the 14th are mostly flat with weak, poor surf – the combined energy is pretty anemic (130 and 69 for Sunday, then 192 and 214 for Monday). The wind is offshore from the WNW, which is fine, but with waves only 1 to 2 ft, it’s barely worth getting wet.
Things start to tick up on Tuesday the 15th. Swell height creeps up to 2 ft from the SSW with a long period of 19-20 seconds, pushing the energy into the moderate range (352-357). It's still only marginal though, with that long period tending to straighten out at a beach setup like Lymans. The wind stays light and offshore, but it's not until Wednesday afternoon that we finally get a decent window. The 16th of September sees a 3 ft SSW swell with a long period of 18 seconds and glassy conditions. The energy is solid at 443 and the surf should be clean. That's the first real standout of the forecast – a good opportunity for a paddle.
There's a bit of a lull after that. Thursday the 17th through Saturday the 19th see the swell drop back down and the wind becomes more cross-onshore or glassy, but with inconsistent energy. Saturday afternoon the 19th brings another glassy window with 3 ft SSW swell and strong energy (532), but it's only a brief moment.
The following week starts with more promise. Monday the 21st has a 3 ft SSW swell with a period of 13 seconds, and the afternoon turns glassy with decent energy (330) – another good session for sure. But then Tuesday the 22nd drops off into tiny, poor surf.
The real standout of the entire forecast comes at the very end. Monday the 28th of September: a 3 ft SSW swell, with a very long period of 18 seconds, pushing the combined energy up to 472 – that's a solid, powerful groundswell. And the wind is glassy from the WNW. That’s the one to circle on your calendar. Lymans is a reef and point setup, so that long-period energy should wrap in nicely and hold its shape. It is a fairly consistent break, but crowds are possible here, so get in early for the cleanest sets.
Right now the water temperature is pretty average for this time of year, nothing wild.
So to sum it up: a lot of small, ordinary days, but Wednesday afternoon the 16th and Monday the 28th are your best bets, with the 28th looking like the absolute winner. Keep your eye on that one.
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.
