The Lowdown
G’day, Rusty here.
Alright, let’s not sugar-coat it. The first week of this forecast is a real wasteland. We’re looking at a long, flat stretch where the ocean’s got nothing to offer. You’ll be better off fixing your dings than paddling out.
The only spot in the conversation is Lymans. It’s a reef and point setup that breaks fairly consistently, but even it’s struggling to find any love.
From the 17th through the 25th, it’s a whole lot of nothing. Swell heights are stuck between 1ft and 3ft, with weak to moderate energy readings mostly between 48 and 341. There are a few glassy moments, like the 18th afternoon and the 23rd afternoon, but with almost no swell, you’re just looking at a flat, clean ocean.
Then, on Thursday the 27th, things change in a hurry. A proper SSW swell arrives, pushing 7ft on the face with a 12-second period. The energy jumps to a strong 1251 to 1323. Thursday afternoon goes glassy, and that’s the first real signal. This is too much for the beginners, but for everyone else, it’s game on.
But Friday the 28th is the one. The swell peaks at nearly 8ft from the SSW, with the same 12-second period, and the energy readings are a thumping 1588. With a glassy morning, this is the standout session of the entire window. This is strictly for the experts—anything over 8ft is serious business. The point should be handling it beautifully, but you need to bring your A-game.
After that, it drops off quickly. The 29th is still a solid 7ft, but the winds turn cross-onshore and it gets messier. Then it falls off the cliff down to 2ft for the 30th and 31st. There’s a clean afternoon on the 31st with 3ft to 3ft from the SSW, but it’s a shadow of what Friday will be.
So, if you’re only going to paddle out once, make it Friday the 28th. The direction is perfect for Lymans, the wind will be off the land, and there’s plenty of power. Mark it down.
And the water’s warm, sitting at 81°, which is a touch above the average for this time of year. Nothing crazy.
Stay patient, stay sharp.
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.
