The Lowdown
Right, let’s have a look at what’s coming up for Lymans.
So, for the next week and a half or so, it’s a bit of a mixed bag. We get a pulse of decent-sized swell early on, but it’s messy with the wind, and then it just drops off into a long, flat spell. No real standout days that’ll have you ringing in sick, but there’s a window to get wet if you’re keen.
It all kicks off this Sunday, September 6th. The morning is cloudy with a light westerly breeze blowing onshore, holding swell around 5ft from the SW with a 12-second period. The combined energy is moderate (563). Not great, but it’s something. The real action though is Sunday afternoon. The rain clears, the wind swings SW at just 3 mph and goes glassy. That’s the good stuff. Swell bumps up to 5ft from the SW, still 12 seconds, and the energy jumps up to moderate (974). That’s your best bet of the whole outlook – clean, lined-up waves at Lymans. This is a reef and point, so that longer period will wrap in nicely.
Monday the 7th sees the swell push over 7ft, with 7ft from the WSW and a long 14-second period, energy up to strong (2453). But the wind is a light cross-onshore from the NW at 6 mph, which will put a bit of bump on the face. It’s still surfable for the experienced, but it won’t be as clean as Sunday arvo. Monday afternoon is much the same, 7ft and cross-onshore.
Tuesday the 8th drops a touch, still around 7ft from the WSW, but the wind gets stronger and more cross-onshore from the SSW at 9 mph, making it fairly choppy. Not a classic.
Then it falls apart. From Wednesday the 9th onwards, the swell drops right away. We’re looking at knee-to-waist high stuff, mostly under 3ft, with periods all over the shop. There’s a long stretch from Wednesday the 9th through to Saturday the 19th where the surf is just poor to marginal. There’s a brief, tiny uptick on the 15th of September with a 2ft swell but a very long 20-second period, and again on the 16th of September with glassy conditions on a 2ft, 18-second swell. That Wednesday afternoon on the 16th, with WNW wind at 3 mph going glassy, is about as good as it gets in that flat spell. But you’re still only looking at small, clean waves – fun for a log, but nothing to get excited about.
The water temperature is about average for the time of year, so no surprises there.
So, if you’re picking a time, it’s Sunday afternoon, September 6th. The glassy conditions and chest-high swell from the SW will make for the cleanest, most fun waves of the period. After that, you’re waiting on forecasts to change.

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.
