The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Honestly, it’s a slow start. We’re looking at a lot of small, messy days before anything really gets going. The water is sitting at 80°F at Lymans, which is about 1°F warmer than usual for this time of year, so nothing too wild, just a touch above average.
The first real glimmer of something worth paddling out for hits on Wednesday, 22 July morning. The swell picks up to 2ft from the SSW, but the period is a whopping 24 seconds – that’s proper groundswell. The combined energy is sitting at 513 (moderate wave energy), which is a decent punch. Thing is, with a period that long, it’s going to be a bit tricky at the beach breaks; it’ll bend more around the reef and point at Lymans. The wind is light and offshore from the W, so the surface should be clean. It’s a morning session for the patient ones.
The real standout, though, is Thursday, 23 July afternoon. Swell bumps up to 3ft from the SSW, period still holding at 19 seconds, and the combined energy hits 680 (moderate wave energy). The wind is light cross-onshore from the WSW, so it’s not perfect, but it’s manageable. This is the best of the bunch for the first week – a solid, rideable groundswell at Lymans.
Things get a bit quiet again after that, with a few marginal days. Then, on Monday, 27 July afternoon, we get a treat. The wind goes glassy, absolutely flat calm, with a clean 3ft SSW swell (14-second period). The combined energy is 330 (moderate). This is the kind of session where you’ll see your own reflection in the wave face. It’s small but perfect.
And if you’re looking ahead, Sunday, 2 August morning is another glassy beauty. The wind is dead off the water, with a 2ft WNW swell (16-second period) and 274 combined energy (moderate). It’s not a big day, but it’ll be smooth as silk.
So, the best on offer: Thursday, 23 July afternoon for the most size and grunt, and Monday, 27 July afternoon for the purest, glassiest conditions. Crowds at Lymans can be an issue on the better days, so get in early.
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.
