The Lowdown

Alright, Rusty here again. Let’s break down this local surf outlook.

Truth is, this is a drawn-out run of tiny, mediocre surf at Lymans (reef and point). The first week and a half is a real grind, with persistent cross-on breezes and a mess of changing swell periods. Water temperature sits right at about 82°, which is just slightly warmer than usual for the time of year – not a big deal, but enough to feel on a calm day.

The real bright spot lands on Monday, September 21st. A 3ft south-southwest swell runs in with a 13-second period, and by the afternoon the wind drops to glassy. For a reef and point, that means a mirror-smooth surface. The energy is moderate (293). This is far and away your best chance for a clean, fun wave over the next two weeks.

After that, things go flat fast. By Tuesday the 22nd, the swell drops to 2ft from the north with a shocking 6-second period – basically just wind chop (energy 26). That kind of short-period stuff has no power to wrap properly into Lymans. It’s a dead zone.

There is one more flicker of hope on Saturday, September 26th. A 2ft south-west groundswell with a 16-second period hits in the afternoon, with glassy conditions. That's a proper long-period pulse, and for a reef and point spot, that will definitely offer the best shape of that week. Crowds are listed as "sometimes," so expect a few others out. The energy is moderate (323), but the wave quality should be the best you’ll see in the second half.

The rest of the outlook is just small, onshore mornings and cross-on afternoons, with most swells barely reaching 2ft. Very tame.

Best bet: Monday afternoon the 21st for that glassy, clean surf, and keep an eye on Saturday afternoon the 26th for a longer-period pulse that could produce the best shape.

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.
