The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – it’s a rough stretch ahead for Lymans. This reef and point break usually has its moments, but over the next 16 days the swell window is barely open, and the wind’s got it all wrong. We’re looking at a long, quiet run before anything even comes close to being worth a paddle.
The water’s sitting at 82°, which is about a degree warmer than usual for this time of year – nothing wild, just a little extra warmth in the mix.
The first real glimmer of hope doesn’t show up until Saturday the 15th. That afternoon we see a small bump of swell at 5ft from the NNE with a period of 7 seconds, and the wind turns cross-offshore, cleaning things up nicely. Combined energy hits 254 (moderate). It’s not pumping, but it’s the best of a pretty average bunch. For beginners, that 5ft might be a bit of a handful, but more experienced surfers could find a few fun ones.
Then we go dead again for a week. Sunday the 16th through to Saturday the 22nd is a total write-off – tiny, onshore winds, and barely any energy in the water. You’d be better off staying home.
The next tease comes on Sunday the 23rd. Morning and afternoon both show swell around 3ft from the SSW with a 15-16 second period – that’s proper long-period groundswell, which brings energy and shape. Combined energy is strong (439 and 423). But the wind is stubborn cross-on, so it’ll be lumpy and messy. Still, for a dedicated local, the long lines and the direction matching that optimum WNW window make this the standout moment. Keep your expectations low though – those 3ft waves won’t blow your mind.
Monday the 24th afternoon is worth a mention because glassy conditions pop up with a 2ft SSW swell at an incredible 18 seconds, but combined energy is moderate (249). It’s tiny but perfect if you’ve got a longboard and want a silky session.
Into the final days, Tuesday the 25th sees the biggest swell of the whole outlook – 4ft from the SSW at 15 seconds, with combined energy roaring to 776 (strong) in the afternoon. That’s the most power we see. But the wind is onshore and the conditions are only marginal. For experts only – the size is getting up there, and the chop will be a challenge.
After that, Wednesday the 26th and Thursday the 27th slip back into nothingness. All in all, it’s a lean 16 days. No true pumping sessions, just a couple of windows for the patient surfer.
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.
