The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s brewing for the next couple of weeks.
First off, I gotta be straight with you – it’s a pretty quiet stretch ahead. The swell energy is just not there for most of the period. We’re looking at a long gap of nothing but small, weak, and choppy conditions before we get anything that’s even worth getting damp for. The water temp is sitting at a balmy 80°, which is about average for this time of year, so no surprises there.
The only spot that’s on the cards is Lymans, a reef and point set-up that’s fairly exposed to the west-northwest. It’s a beginner-friendly wave, and it’s fairly consistent, but don’t expect much.
We start off on Monday the 20th of July, and honestly, it’s a total write-off. We’ve got a tiny 1.0ft swell from the WNW with a 12-second period, but the wind is cross-on and the energy is weak (45). The conditions are poor, and the score is a zero. That sets the tone for the next several days.
Tuesday the 21st is more of the same – tiny 1ft waves, cross-on wind, and weak energy. Wednesday the 22nd shows a little bump in the water, with a 2ft swell from the SSW, but the energy is still moderate (460) and the wind is ruining it. Thursday the 23rd is a bit of a tease: we get a 3ft swell from the SSW with a 19-second period, and for the first time in the afternoon, we see a light offshore wind from the WSW. The energy is up to 684 (moderate), and the score is a 2 out of 10. That’s the best we’ve seen, but it’s still just marginal.
Friday the 24th and Saturday the 25th offer similar glimpses of hope. The afternoon of Friday the 24th sees a 3ft SSW swell with a 17-second period, clean offshore wind, and energy of 784 (moderate). Saturday the 25th afternoon bumps up to 4ft from the SSW with a 18-second period, clean offshore wind, and the highest energy of the whole run at 838 (moderate). These are the standouts, but they’re still only scoring a 2 out of 10. The long period will make them a bit more lined up at Lymans, which is a point, that’s a good thing.
Then we hit Sunday the 26th of July. The morning is a 3ft SSW swell, decent, but the afternoon is where it gets interesting. The wind drops to glassy, absolute zero, and the swell holds at 3ft from the SSW with a 16-second period. The energy is 614 (moderate). This is the closest we get to “good surf conditions” in the whole forecast. The score is a 2 out of 10, but that glassy wind is a huge plus for clean waves.
After that, it’s a slow fade. Monday the 27th drops back to 3ft, Tuesday the 28th has a glassy afternoon with a 2ft SSW swell, but the energy is low (203). From Wednesday the 29th of July all the way through to Tuesday the 4th of August, we’re back to tiny, weak swells, mostly under 2ft, with poor conditions and a lot of cross-on wind. The energy drops into the double digits, and there’s nothing to get excited about.
So, the bottom line: if you’re desperate for a paddle, the best bet is the afternoon of Sunday the 26th of July at Lymans. The glassy conditions will make that 3ft swell feel clean and fun, even if it’s not big. The afternoon of Friday the 24th and Saturday the 25th are also worth a look for the offshore wind and a bit more size. Everything else is a skip. For a beginner-friendly spot, it’s not a bad time to learn on the small days, but don’t expect any barrels.
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.
