The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking for Lymans over the next couple of weeks.

Honestly, the start of this outlook is pretty quiet. We’re looking at a real slow burn. The first solid chance of anything decent doesn't really show up until Friday the 21st. Before that, from Sunday the 16th right through Thursday the 20th, it’s all poor surf conditions with tiny waves.

Friday morning the 21st is still small, but by Friday afternoon, things finally get interesting. The wind goes glassy, which is a huge plus, and there’s a 2ft swell coming from the SSW with a solid 16-second period. The combined wave energy is moderate (178). It’s still just surfable, but that glassy wind will make it feel cleaner than it should be. This is your first real window to get wet.

Saturday the 22nd and Sunday the 23rd are a bit of a letdown again, with the wind turning back cross-onshore and energy dropping. The pattern stays messy through Monday the 24th and Tuesday the 25th. Tuesday afternoon does see a bump in combined energy to 335, but the conditions are still described as marginal, so don’t get too excited.

Now, the best window in the whole 16-day run looks like Thursday the 27th through the end of the month. Thursday morning (27th) shows a 3ft SSW swell with a whopping combined energy of 557 – that’s strong wave energy. The morning is still marginal, but by Thursday afternoon the wind goes glassy again, the swell holds at 3ft, and the energy is still high at 397. That’s the standout session: glassy, groundswell, and enough push for a fun wave at Lymans. It’s a reef and point break here, so that longer period (15 seconds) will wrap in nicely.

We then get a lull on Friday the 28th and Saturday the 29th as a tiny, short-period NNE windswell moves in. The combined energy drops to 76 and then 29 – very weak.

But hold on. Sunday morning the 30th is another real ripper. We see a 2ft SSW groundswell with a very long 19-second period and glassy wind again. Combined energy is a strong 390. This is groundswell perfection for a point break like Lymans (Region_URL). The sets will be clean, lined up, and worth the paddle. The water temperature is sitting at about 81°F, which is pretty normal for this time of year, so no surprises there.

The outlook ends on Monday the 31st with a building 2ft SSW swell and moderate energy (344), but the wind turns cross-onshore and drops the quality back to marginal.

So, my two picks for the best waves: Thursday 27th afternoon and Sunday 30th morning. Both have glassy wind, solid groundswell, and solid energy. These are the sessions to pencil in.

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.
