The Lowdown
Alright folks, Rusty here, let's get straight into what's on the menu for the local stretch.
Right off the bat, we're looking at a pretty quiet period ahead. The first real window of interest doesn't kick off until Thursday the 20th of August, and even then, it's not much to write home about. We've got a small window of surfable waves, but it's going to be a bit of a waiting game through the end of the month.
The water at Explosivos is pumping in at a warm 70°, which is a massive 8° above the norm for this time of year. That's a seriously unusual anomaly, so you'll be in for a very warm, tropical-feeling session.
For the first week, from Thursday the 20th through to around Wednesday the 26th, the swell is small and struggling. We're looking at mostly 1 ft to 4 ft swell from the south, with short periods around 8-9 seconds. The combined wave energy is weak, sitting between 167 and 775, so there's not a lot of juice in the water. The winds are light, mostly cross-on or onshore, which is about the only saving grace. It's a marginal, workable setup, but don't expect any gems. The best of this early period is probably Thursday afternoon the 20th, with a 6 ft south swell and a combined energy of 682, but it's cross-on wind that will keep it a bit messy. It's a low-expectation paddle.
Then we hit a real lull from the 22nd to the 26th. The swell drops further, and we're into 1 ft to 3 ft territory with very weak energy. The wind is still light, but the surf is just too small to be any good. This is a solid gap of a few days where you're better off doing something else.
Now, here's where it gets interesting. The real standout, and the one you want to circle on your calendar, is Friday the 28th of August. We’ve got a proper swell building in. The morning brings a 7 ft swell from the south-west, with a very long period of 16 seconds, and the combined energy is a massive 2415. That's a heap of power. The wind is light and offshore from the south-west, so it's going to be clean. But, and this is a big but, at 7 ft and with that long period, this is a beast for advanced surfers only. The forecast notes it's "too big for this break," and I have to agree. This is expert territory. The afternoon pushes it even bigger to 8 ft, with energy hitting 2875. It's a phenomenal window of powerful, long-period groundswell, but it's not for the faint of heart. This is a serious, heavy, and powerful wave.
Saturday the 29th of August is still holding a solid 7 ft from the south-west in the morning, with energy at 1873, but the wind swings cross-on, taking the shine off a bit. The afternoon drops to 6 ft, but it's still a hefty session.
After that, we ease back into a more marginal pattern through the first week of September. The swell drops to 5 ft to 7 ft from the south, with periods dropping back to 9 seconds. The energy is still moderate (around 684 to 1248), but the wind is mostly cross-on or onshore, so it's a step down in quality. Thursday the 3rd of September afternoon shows a bit of promise with a 5 ft south-west swell, a 16-second period, and a cross-shore wind, giving it a bit more shape. But overall, the second week is a lot less consistent and less powerful than that Friday the 28th.
So, the bottom line: there's a massive gap of small, weak surf until the end of the month. The only true standout, and the one that gets the blood pumping, is Friday the 28th of August. If you're an expert, that's your day. For everyone else, you're looking at small, marginal waves through the rest of the period.
Rusty.

Information about the Explosivos Surf forecast
The above surf forecast table for Explosivos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Explosivos can be found by selecting the local surf guide option on the grey menu. Our Explosivos 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 (Explosivos) 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 Explosivos 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.
Explosibles is 34 km (21 miles) from the very large city of Mala. If you plan a holiday in Lima, look for hotels and other accommodation in Mala. Mala has rooms for a wide range of budgets as well as cheap car hire and transport links.
