The Lowdown
Alright, this is Rusty, and I’m not gonna sugarcoat it. The next 16 days at Lymans is a long, slow grind. Tiny, weak surf with very few moments where the stars align. It’s a real test of patience.
The pattern is set for a while. We start off with a couple of days of real small stuff, then we hit a bit of a lull in the middle of the week before a slight bump in size arrives. The standout moments are few and far between, but there are a couple of windows where the conditions come together.
Thursday the 6th and Friday the 7th are a total loss. The swell is a pathetic 1.0 ft to 1 ft from the SW with a period of 13-14 seconds, and the wind is junk. The energy is weak (54-60). Saturday the 8th morning is flat, but the afternoon surprises you. The wind goes glassy, and a 1 ft SSW groundswell (18-second period) shows up with a decent energy jump (137). It’s tiny, but it’s clean. If you’re on a longboard, you might get a couple.
Sunday the 9th is back to ordinary. The real tease starts Monday the 10th. The swell bumps up to 3 ft from the SSW (15-second period), with energy at 332. The morning is messy, but the afternoon goes glassy with 2 ft surf. It’s rideable, but still nothing special. Tuesday the 11th holds similar size, 3 ft, but the wind is side-on.
Now, here’s the one true standout. Wednesday the 12th. The morning has 3 ft SSW swell (13 seconds, 323 energy), but the wind is onshore. The afternoon is the moment. The wind drops to completely dead calm, glassy. The swell is a clean 3 ft from the SSW, with a solid 335 energy. The guidance says "expect good surf conditions." That’s your best shot. It’s a reef and point break, so that longer-period groundswell will wrap in nicely. The water temp is a warm 81°, which is a full 2° above normal for this time of year—a nice bonus for a late afternoon session.
After that, the wheels fall off. From Thursday the 13th right through to the end of the forecast, the swell drops back to tiny 1 ft to 2 ft windswell from the north and northeast, with periods below 8 seconds. The energy readings are anemic (7-75). The winds are a mess of onshore and side-onshore. There’s a brief glassy moment on Saturday afternoon the 15th, but with only 2 ft of 8-second north-northeast windswell and 75 energy, it’s still a poor surf. The rest of the third week is a write-off.
So, to sum it up: the only real window you want to be in the water is Wednesday afternoon, the 12th of August. That’s the pick of the bunch. The rest is a long gap of poor to flat conditions. It’s a tough run for Lymans.
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.
