The Lowdown
Alright folks, Rusty here, and I’ve got the lowdown on what the next couple of weeks are looking like for your local stretch.
We're starting off with a bit of a frustrating situation, to be honest. The coming days are going to be tricky. The first real window we're watching kicks off on Monday the 17th, but it’s not a great one. On Monday afternoon, we’re looking at a clean 3ft swell from the Southwest at a solid 13 seconds, which is a nice groundswell, but the wave energy is only moderate (567). The wind is a cross-shore, so it won't be glassy, and it’s only scoring as marginal due to tide issues. The water is a very unusual 70°, which is a whopping 8° warmer than normal for this time of year – that’s definitely a standout for your first surf.
Tuesday the 18th is where things get serious, but not in a good way for most of us. The swell jumps up to a solid 7ft-8ft from the SW/SSW. The combined energy for Tuesday morning is strong (1634). That’s a lot of power, and the reports are calling it too big for this break. If you’re an expert, the Tuesday morning session with lighter winds could be on, but with that size and an onshore component later, it’s gonna be a brute.
Wednesday the 19th stays big with 7ft-8ft waves, but the wind starts to get a bit messy. The surf quality is being called poor for this break because it's too powerful. Honestly, with this much wind and size, this setup looks way more interesting for kite surfing than paddle surfing.
We then hit a long, quiet spell. From Thursday the 20th all the way through to the morning of Friday the 28th, this is going to be a proper flat spell. Most days are 'marginal' or 'poor', with wave heights dropping to under 3ft. There are about 8 or 9 days in there where you’d be wasting your time. Don't bother checking the cam until the end of the month.
The sole standout in this whole 16-day window is Friday the 28th and the weekend of the 30th of August. Friday morning brings a 5ft swell from the Southwest with a very long period of 18 seconds (energy 1528). By Friday afternoon, it cleans up to 5ft from the SW at 17 seconds with a cross-shore breeze. That's proper groundswell, and even with a touch of cross-chop, it will have some good shape at this sandbar. The weekend of the 30th sees 6ft waves from the SW on Saturday, dropping to 6ft on Sunday. The period is still long and strong, peaking at 15 meters. This is the best bet for a decent session, but keep in mind this is over a week away, so it's promising but not locked in yet. It might be a little too big for beginners, but for anyone who’s comfortable, it's your window.
After that, it fades back down to small, marginal stuff rolling into September. Keep your eyes on that last weekend of August.
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.
