The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the cards for Lymans over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week is a total bust. From Wednesday the 5th all the way through Sunday the 9th, it’s flat as a pancake. Swell is barely 1 to 2 feet, coming from the SW or SSW, and the energy is weak – we’re talking under 100 units. Winds are cross-on or onshore, and every wave report is screaming “poor surf conditions.” Don’t even think about paddling out.
Monday the 10th sees a little bump, but it’s still nothing special. Swell hits 3 feet from the SSW with a long 15-second period, and the energy jumps to 332 (moderate), but the wind is messy and the forecast is calling it “marginal.” It’s a tease.
Now, here’s the one to circle. Wednesday the 12th of August is your standout. The morning looks glassy – wind from the WNW at just 3 mph, and a clean 3 foot SSW swell with a 13-second period. The energy is solid at 307 (moderate), and the wave report says “expect good surf conditions.” That’s the session you want. The water is a warm 81°, about 2° warmer than usual for this time of year, so it’s a touch toastier than normal – real nice.
After that, it’s back to the doldrums. Thursday the 13th through to the end of the period is mostly small, weak, and messy. Swell hangs around 2 to 3 feet, but winds are all over the shop – onshore, cross-on, or variable. There’s a brief moment on the afternoon of Monday the 17th where the wind goes cross-off from the SE, cleaning things up a bit, but at 2 feet and 13 seconds from the W, it’s only “surfable” – not a standout. The afternoon of Tuesday the 18th also goes glassy, but again, it’s a tiny 2 foot W swell. Not worth rushing for.
Overall, the best bet is the morning of Wednesday the 12th. The glassy conditions and that 3 foot SSW groundswell will be fun for beginners and longboarders alike. Keep your expectations low for the rest of the window – it’s mostly a waiting game.
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.
