The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, mate, the first week is a bit of a grind. We’ve got a long stretch of marginal surf and tricky conditions. The whole run from the 27th right through to the 5th of August is pretty average. The swell is there, but it’s mostly small, a bit short-period, and the wind is rarely on our side. You’ll see a few cross-on and cross-shore breezes that just mess up the face. It’s not a total write-off, but you’re gonna be working for any half-decent wave.
The standout – and I mean the only real standout – is Explosivos (sandbar). It’s a consistent, exposed spot that knows how to handle a South-West swell, which is exactly what we’re getting. The real magic shows up on the morning of Sunday, the 9th of August. We get a solid 7ft swell from the SSW, with a 13-second period – that’s proper groundswell energy. The wind is light and offshore from the SW, which is perfect for a sandbar. The wave energy is strong at 1811, so there’s a lot of power in the water. The catch? That 7ft is pushing it for the regular crew; this one is for the advanced surfers only. The direction is bang on what this spot loves, but on a sandbar, a long period swell like that can sometimes make the waves a bit too straight. Still, on that morning, with offshore winds, it’s the best you’re gonna get. Expect crowds here, it’s exposed and consistent, so you won’t be alone.
The water temperature is a wildcard. As of the 27th of July, it’s reading 71°F, with a massive anomaly of 9°F. That’s way, way warmer than you’d expect for this time of year. Very unusual.
If you’re looking at the second week, the 10th and 11th of August keep the swell size up around 7ft to 7ft, again from the SSW. The energy is high (over 2000 on the 10th), but the wind is a bit more cross-on, so it won’t be as clean as that Sunday morning. The 11th is a bit more of the same. It’s still big, still for experts, but the quality drops off with the wind. For the regular punter, the 9th of August morning is the one to circle on the calendar. Everything else is a waiting game.
Rusty signing off.

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.
