The Lowdown
Alright, let’s have a look at what’s on the cards for the only spot in the window, Lymans.
Honestly, it’s a pretty quiet run for the next couple of weeks. There’s a big gap at the start with nothing really worth paddling out for. The first real chance to even think about a surf doesn’t show up until the afternoon of Wednesday the 23rd, and even then it’s a marginal call. The whole forecast is a real test of patience.
The water temp is sitting around 80°, which is about normal for this time of year, so no surprises there.
Alright, let’s walk through it. Tuesday the 21st is a write-off – tiny 1ft swell from the SW with a weak energy of just 82, and the wind is cross-onshore. Not happening. Wednesday the 22nd stays poor, with the morning showing a 2ft swell but the wind is onshore, and the energy jumps to 457, but it’s still messy. The afternoon gets a little better with a 2ft swell from the SSW but it’s cross-shore. Still a no-go.
Thursday the 23rd morning is again poor, with 3ft swell but cross-onshore wind making it choppy. The afternoon is the first glimpse of something, with 3ft from the SSW, the wind goes light onshore from the WSW, and the energy is moderate at 694. It’s a marginal window, but it’s the first real chance.
Friday the 24th has a similar story – 3ft from the SSW, but the wind is onshore in the morning. The afternoon is the best of the bunch so far, with light onshore wind and a solid energy reading of 793. The swell is a bit short period at 17 seconds, but for a point and reef setup like Lymans, that long period groundswell can actually line up nicely. It’s a marginal call, but it’s the standout of the first week.
From Saturday the 25th through to the end of July, it’s all marginal to poor. The swell sticks around 3ft to 4ft, but the wind is mostly cross-on or cross, and the energy fluctuates. The afternoon of Saturday the 25th has a 4ft swell from the SSW with 838 energy, but the wind is cross-on. It’s okay, but not clean.
The best chance in the whole outlook might be the afternoon of Tuesday the 28th. The swell drops to 2ft from the SSW, but the wind goes glassy – that’s a major positive. The energy is moderate at 247. It’s not big, but if it’s glassy and the tide is right, Lymans can offer a few fun ones. The crowd factor is “sometimes” here, so you might not have it to yourself, but it’s worth a look.
After that, it’s a slow fade. The first week of August sees tiny swells, mostly 2ft to 2ft, with poor winds and low energy. The afternoon of the 5th has a glassy window with 2ft from the SW and 172 energy, but it’s just ordinary conditions.
So, the standout window is the afternoon of Friday the 24th, with that 3ft long-period groundswell and light onshore wind, and the glassy afternoon of Tuesday the 28th. Neither is a classic, but it’s all we’ve got. The rest is a waiting game.

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.
