The Lowdown

G’day, it’s Rusty. Let’s be real: the next two weeks at Lymans (Big Island) are mostly a write-off, but there’s a couple of brief windows where it might clean up enough for a paddle. Here’s the rundown.

We start off flat and messy. From Saturday the 12th through Monday the 14th, the swell is tiny – around 1ft at most – with a long 16-second period, but it’s coming from the southwest, which puts a cross-on wind on the break. The energy is weak (around 143 – moderate at the low end), and it’s not worth getting wet for.

Tuesday the 15th bumps up slightly to 2ft, but the period drops to 20 seconds. Energy climbs a bit (370 – moderate), but the conditions are still rough. Wednesday the 16th is where things get interesting. The swell builds to 3ft from the SSW, with a period of 18 seconds, and the energy comes up to 443 – a solid moderate push. The key window is Wednesday afternoon: the wind goes glassy, and the forecast says “expect good surf conditions.” This is your first real highlight. Water temp is 28°, which is about normal for this time of year. It’s small, but clean, and that long-period groundswell will wrap around the point nicely. This is the best of the first week.

Thursday the 17th also has a glassy afternoon, with 2ft from the SSW and energy around 418. If you can dodge the showers, it could be a fun one. But Wednesday afternoon is the pick.

After that, it falls apart. Friday the 18th has a bit more size – 3ft – but the wind is cross-on and it’s messy. The weekend of the 19th and 20th is stormy and inconsistent. Monday the 21st sees the wind pick up to 20 km/h from the northwest, which chops things up completely.

From Tuesday the 22nd onward, the swell collapses. It drops to 1ft with an energy reading of just 9 – that’s about as flat as it gets. There’s a tiny pulse around Sunday the 27th, with 2ft from the SSW and a 20-second period (energy 404 – moderate), but the conditions are marginal.

So, the standout is Wednesday the 16th afternoon. It’s not big – 3ft – but the glassy conditions and that clean SSW groundswell should make for some great, forgiving waves off the point. The second pick is Thursday afternoon the 17th, but it’s a close second. Don’t expect much size at all – it’s all about the quality of the waves, not the height. There are long gaps here, almost a week of nothing, so pick your moments.

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.
