The Lowdown
Alright, let's get into it. Looking at the full 16-day stretch, it's a slow burn for Lymans, with only a couple of real opportunities that might get you stoked. The first few days are pretty dead, but there's a glimmer of hope around the 10th, and then a bigger, more serious pulse right in the middle of the month. It's not going to be all-time, but there are definitely a few sessions worth marking on the calendar.
Right off the bat, the surf is tiny. Saturday the 8th has some knee-high slop, with a southwest wind that's mostly on it. The swell energy is weak, around 145, and it's just not doing anything for the reef and point. Sunday the 9th is even worse, a real write-off. It's a pretty quiet start, with a couple of days of nothing worth getting wet for.
Then Monday the 10th rolls around and things start to look a little more interesting. The swell bumps up to 3ft, with a nice long 15-second period from the SSW. The morning is still a bit iffy, but the afternoon is where it's at. The wind drops to a glassy 3 mph from the SW, and the forecast says to expect good surf conditions. The energy jumps to 300, which is moderate, but that clean, glassy surface will make it feel way better than the numbers suggest. This is probably the pick of the first week, a proper little clean-up session.
After that little pulse, it fades back out. Tuesday the 11th has a bit more size but the wind is messy, and it just looks crumbly. Wednesday and Thursday are similar stories, just poor surf conditions and onshore winds. There's a bit of a blip on Friday the 14th with a 4ft swell showing up, but the period is a short 7 seconds from the NNE, which is junk. It'll be lumpy and disorganized, not worth your time.
Now, for the real standout. On Sunday the 16th, the swell jumps to 8ft. The energy reading is 938, which is strong, and it's coming from the SSW with a 9-second period. This is a big step up in size. The wind is onshore, but with that much juice, it's going to be powerful. At Lymans, this is a reef and point setup, and a southwest swell like this is what it wants. This is big, proper surf. At 8ft, this is heading well into expert territory. It's not for the faint-hearted, and the onshore wind is a bit of a shame, but the raw power will be something to see. This is the one day that really stands out as the best on offer, but it's a serious session.
The rest of the second week is a real letdown. From the 17th through the 22nd, the swell drops back down to knee-high dribble, with weak energy readings often below 150. The wind is mostly cross-onshore, and the period is all over the place. It's just a flat, forgettable stretch. You'll be checking the forecast hoping for a change, but it just doesn't come.
There is one final glimmer on the 23rd, the last day of the window. The swell comes back up to 3ft with a 15-second period from the SSW, and the energy is back up to 270. It's still a marginal one, but that long period is a good sign. It's a promise of things to come, even if it's just a whisper.
So, to sum it up: the first week is a grind until that glassy Monday afternoon. The big day is the 16th, a proper, powerful swell for experts only. After that, it's mostly flat until a hint of something better on the 23rd. Keep your eyes on that middle of the month window.

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.
