The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Lymans.
Honestly, this is a pretty poor stretch for waves. We’ve got a long, drawn-out run of days where the conditions just aren’t coming together, and there’s a big gap of nothing worthwhile. It’s a quiet spell.
The first sniff of anything surfable doesn’t really show until later in the period. For the first week and a half, from Monday the 10th through to Saturday the 22nd, it’s a write-off. Wind, swell, and tide just aren’t lining up. You’ve got a few days with some small, long-period groundswell, but the wind is cross or cross-onshore, so it’s chopped up or messy. The water temp here is 81°F right now, which is about average for this time of year.
Now, if you’re patient, there’s a little glimmer. Late in the forecast, on Saturday afternoon the 22nd, we finally get a break. The wind goes glassy at Lymans, which is a real treat. It’s a reef and point setup, so that long-period swell tends to line up nicely on these kinds of breaks. The swell is a tiny 2 ft from the SW, but that combined swell energy is a weak 121, so don’t expect any power. It’s small, but it’ll be clean and rideable for a beginner, though the crowd might be *likely* here. It’s the only real window.
Then on Tuesday the 25th, there’s a bigger ripple of activity. The afternoon shows a pulse of 4 ft swell from the SSW with a period of 16 seconds. The energy jumps up to 790, which is a moderate pulse. The wind is onshore, though, so it’s a bit suspect. It’s a marginal call at best, but if the tide and wind play nice, there might be a few clean ones for the experienced crew.
Bottom line: This is one of those stretches where you don’t sell the farm. The standout is glassy, tiny surf on Saturday the 22nd for a longboard or a foiler, and maybe a slightly bigger but wind-affected window on the 25th. Everything else is best left for a different hobby.
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.
