The Lowdown
Alright folks, Rusty here. Let’s break down what’s cooking at Lymans.
First off, it’s a quiet start to the period. The first few days are a write-off – absolutely nothing happening on Friday the 4th, with a tiny 2ft north windswell and a weak 20 units of energy. You’d be better off staying home. The weekend doesn’t offer much either, with small, messy, cross-onshore junk.
Things finally start to rumble to life on Monday the 7th. The swell builds quickly through the day, hitting 8ft from the WSW by morning, with a solid 14-second period and energy reading 3484. By the afternoon, it’s pushing 12ft from the SW, period still 14 seconds, and the energy is pumping at 5518. That’s serious groundswell. The wind is light cross-shore, which is workable, but this is big, powerful stuff. For the experienced crew only. This is the standout session of the whole outlook – raw power and long-period lines. The water temp is about average for this time of year.
Tuesday the 8th is a bit of a mixed bag. The morning swell drops to 5ft from the west with a shorter 10-second period, and the wind is cross-on, so it’s not great. But Tuesday afternoon is a gem. The swell drops to 3ft from the SSW, period lengthens back to 14 seconds, and the wind goes glassy. The energy reading is 1024, and the description says “expect very good surf conditions.” That’s a clean, fun window for a longboard or a fish.
After that, the swell fades fast. Wednesday the 9th is small and rainy, and from Thursday the 10th right through to the end of the 16-day window, it’s mostly flat or tiny. There are a few moments in the second week – like Thursday the 17th afternoon and Friday the 18th afternoon – where you get glassy conditions on tiny 3ft swell, but it’s really just a chance to get wet. The long-range stuff is promising but less certain; keep an eye on it.
Rusty out.

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.
