The Lowdown
Alright folks, Rusty here. Let's break down the next couple of weeks at Huascar. It's shaping up to be a slow burn, so don't expect fireworks right out of the gate. We've got a consistent swell window, but conditions are going to be the main player for a while.
The water is sitting at 64°, which is a solid 4° warmer than usual for this time of year. That's a noticeable bump, so the rubber might be a touch warmer than you'd expect.
The first few days are pretty grim, to be honest. Tuesday and Wednesday are blown out with moderate cross-onshore and cross-shore breezes, and the surf is small and messy. Not worth getting wet for. The energy is moderate at best, with values around 484 to 627, but the quality just isn't there.
Thursday stays small, around 3ft, with lighter winds but still a cross-shore bump. It's marginal at best. Then we finally get a bit of relief on Friday morning. The wind drops to nothing, going glassy, and we've got a 3ft SW swell with a short 9-second period. The energy is weak, at 273, but the clean surface will make it feel better than it is. It's small, but it's the best we've seen. The swell direction is a touch onshore, but that clean face will be a welcome change. It's not gonna be a classic, but it might be worth a paddle if you're desperate.
The weekend then goes flat and weak, with energy dropping to below a hundred. There's some glassy moments, but just not enough push in the water to make it fun.
We then have a run of poor, small surf from the 23rd to the 25th. Swell drops to 1-2ft, a lot of cross-shore wind, and wave energy is weak. This is a proper lull; you'd be better off waxing your board and thinking about the future.
There's a slight lift on the Wednesday and Thursday, the 26th and 27th, but it's still only marginal. The swell hangs around 2ft to 4ft, and the wind is light, sometimes glassy. The energy picks up a bit, getting to 532, but it's nothing to get excited about. The period does stretch out to 14 seconds though, which is a hint of better things to come.
Now, for the main event. Mark your calendars for the 28th and 29th of August. We've got a proper pulse of swell arriving. The waves jump to 7ft to 8ft, with a long period of 16 seconds from the WSW. The energy goes through the roof, hitting 2629, which is strong. This is a serious groundswell. The wind is light, which is a major plus, but it's cross-shore, and the swell direction is a bit west of the optimum. This will groom the point nicely. This is a solid size, so it's not for the faint-hearted. Over 8ft is too big for most, so this peak is going to be an expert's session. The long period is key at a point break like this, so look for those lines to wrap in beautifully. This is the standout of the whole period. Saturday looks good too, a little smaller at 7ft and still with that long-period energy, but the wind picks up in the afternoon which will chop it up a bit.
After that, the swell slowly backs off, but it remains rideable into the first week of September. From the 30th, expect 5ft to 6ft surf, but with a moderate cross-shore wind and shorter periods. The energy drops, but there's still enough push. The 2nd of September looks interesting again, with a pulse of long-period energy (17 seconds) and a 4ft swell, but it's a bit smaller and the wind isn't ideal.
So, to sum it up: get excited for the 28th and 29th. That's the one to circle. The long-range call on the 2nd is promising but much less certain. Other than that, it's a waiting game.
This is Rusty, signing off.

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