The Lowdown
Alright, let's talk Lakey Peak. We've got a consistent run of clean, lined-up swell from the SSW, just what this reef wants to see. Water temp is 80°F, pretty much normal for this time of year.
We're kicking off Wednesday morning (July 29th) with a solid 4ft SSW groundswell. The period is a long 15 seconds, meaning proper energy and good shape on the reef. The ESE breeze is blowing straight offshore, keeping things glassy. The combined energy is moderate (590), but with that offshore wind and the direction lining up perfect, it’s a fun, clean wave for an intermediate. Expect some company though, this spot gets busy.
Thursday (July 30th) keeps that quality going with a touch more power. The morning is clean with 3ft SSW swell and the same offshore wind, but the energy is building. Thursday afternoon picks up to 4ft, still clean.
Friday (July 31st) is where it starts to get serious. The morning session is a standout: 4ft of SSW groundswell with a 17-second period, light offshore breeze, and the combined energy jumps to a strong (1330). This is where the reef really starts to pulse. It’s getting into that intermediate-to-expert zone, but the conditions are pristine.
Saturday (August 1st) is the clear winner for the first week. The morning has 5ft, 16-second SSW swell, glassy offshore wind, and the energy is pumping (1491). By the afternoon, the swell bumps to 5ft with next to no wind. It's as clean as it gets. This is your call.
Sunday (August 2nd) brings the biggest jump in size for this period. The morning is 6ft with an 18-second period, and the energy is very strong (1809). By the afternoon, it hits 7ft with 17-second periods and still offshore. This is excellent, powerful surf for skilled surfers. The size is getting up there, so it's not for the faint-hearted.
The following week, from Monday (August 3rd) through to the end of the forecast, the quality holds but the wind is more variable. You’re looking at solid 5ft to 8ft groundswell, but the wind tends to be cross-offshore rather than straight off. The energy remains strong to very strong, with readings consistently over 1000. Thursday August 6th through Sunday August 9th are the biggest days of this stretch, with swells sitting at 7ft to 8ft and energy readings in the high 2000s to low 3000s. This is big, powerful reef surf for experienced crew only. The real standout for the second half is the morning of August 9th: 8ft SSW, 16-second period, and for once a lighter breeze. That’s a magic window.
There is a massive clean-up set on August 12th, but the swell is predicted to be 10ft to 12ft, which is too big for this break to handle safely. That’s an expert-only day at an exposed spot, if at all. After that, August 13th gets back into the 8ft range and looks excellent with the offshore wind returning.
Overall, you’ve got a full 16 days of surf here. The best windows are the mornings of August 1st and August 9th, with pristine conditions and powerful, long-period groundswell. Get in the water.

Information about the Lakey Peak Surf forecast
The above surf forecast table for Lakey Peak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Peak can be found by selecting the local surf guide option on the grey menu. Our Lakey Peak 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 (Lakey Peak) 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 Lakey Peak 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.
