The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next two weeks are a bit of a grind for Lymans. This is a reef and point set-up that likes a solid WNW swell, but we’re just not seeing that direction in any meaningful size. Most of the period is a write-off for proper surfing, with a few tiny windows of “surfable” waves that are more about getting wet than getting barrelled. There’s a big gap of nothing from now until Tuesday afternoon, the 18th of August, when we finally see a glimmer.

The real standout is Tuesday afternoon, the 18th of August. We’ve got a tiny 1ft swell rolling in from the SW, but the period is a massive 18 seconds – that’s proper groundswell energy. For a reef and point like Lymans, that long period will wrap in and offer some shape, even if it’s small. The wind goes glassy, which is a major positive – clean, smooth conditions. The combined energy is moderate at 92 (moderate wave energy). The water temp is about 82°F, which is pretty normal for this time of year. It’s not a day to charge, but for a sneaky session on a longboard, it’s the best on offer. Keep in mind, with that long period, the sets will be spaced out, so patience is key.

Wednesday afternoon, the 19th of August, is a repeat: 1ft SW swell, 16-second period, glassy winds, and the energy is sitting at 112 (moderate wave energy). Again, it’s small but clean. If you missed Tuesday, this is your backup.

Thursday afternoon, the 20th of August, offers another small window: 2ft from the SW at 17 seconds, glassy, with a combined energy of 165 (moderate wave energy). These are all similar – tiny, clean, and better than nothing.

The rest of the time up to the 25th is mostly poor surf conditions with onshore or cross-shore winds and tiny swell. The 25th of August, Tuesday morning, we see a bump to 3ft from the SSW at 16 seconds, with a combined energy of 360 (moderate wave energy) – that’s the biggest swell of the outlook. But it’s a bit of a tease – the conditions are rated as marginal, and the wind is onshore. Still, if you’re desperate, that morning might offer a few fun ones.

After that, from the 26th of August onward, it’s back to tiny, weak swells and poor conditions. Honestly, for Lymans, this is a blank run. The spot is fairly consistent, but it’s not delivering. The first week is dominated by small, poorly aligned swell, and the second week only shows a brief uptick around the 25th. I’d say don’t hold your breath – forecasts can change, but right now, the board stays in the car.

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.
