The Lowdown
Alright, Rusty here, let’s talk about what’s on the table at Lymans over the next few weeks.
Honestly, looking at the big picture, it’s a pretty quiet stretch ahead. There’s no real punchy swell on the cards, and we’re looking at a lot of marginal surf that’s more about hoping for a cleanup set than charging. The good news is the winds are predominantly light, often offshore, so when there’s a wave, it’ll be tidy.
Right now, on Sunday the 13th, it’s flat and poor. We’ve got a tiny 2ft swell from the SW, but the 15-second period gives it a bit of groundswell character (136 weak energy). The water here is sitting at 82°, so a touch warmer than usual for this time of year. Monday the 14th stays a bit small, but we get proper offshore wind from the West at 6 mph on a 1ft, 23-second pulse. That’s a very long period, which means better shaped waves, but at that size, it’s barely breaking. You’ll be scratching for a ride.
Things start to lift a little from Tuesday the 15th. The morning has 2ft from the SW with a 20-second period, 6 mph WSW offshore wind. The combined energy is climbing (354 moderate). It’s still small, but the quality of the wave might make it a sneaky window. Wednesday the 16th is the best of the bunch this week. We’ve got 3ft from the SSW, light offshore winds all day at 3 mph, and the period drops to 18 seconds. The afternoon shows 457 (moderate energy). That’s enough to get a few clean, peeling lines off Lymans, a reef and point setup that loves that long-period SSW swell direction. This is a highlight—small but clean, and with the wind staying glassy in the morning, it’s a good time to be out.
Thursday the 17th and the rest of the first week stays in that marginal zone. Friday the 18th sees the combined energy peak at 520 in the afternoon (strong), but it’s still only 2ft. The onshore wind from the West at 3 mph is there, but the sheer energy for the size suggests it’ll be more lined up than the height shows. There’s a risk of thunderstorms, though.
Heading into the second week, from the 20th onward, it’s pretty dull. Sunday the 20th morning has the best of it—3ft from the SSW, 15-second period, and 6 mph offshore wind (442 moderate energy). But that’s as good as it gets. After that, we’re dropping into poor conditions, with swell hovering around 1ft to 2ft. A couple of afternoons—the 24th and 26th—go glassy, but with tiny 2ft to 2ft swell, it’s just a float, not a surf. The window on the 28th sees the strongest combined energy in the whole outlook at 551 (strong), but it’s 2ft from the SW at 18 seconds, with cross-onshore wind. It looks more interesting for a longboard or a foil than a proper stand-up session.
So, the call: Wednesday the 16th is the standout. Small, clean, offshore, and that reef setup will handle the long-period SSW pulse better than any beach break. The 28th has the biggest energy, but it’s further out and less certain. For now, keep your expectations low and your wax warm.
Stay stoked.
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.
