The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’re looking at a solid run of swell, but it’s a bit of a mixed bag with the wind. The main event is a consistent southwest groundswell that builds through the period, but you’ll need to pick your windows carefully. The best of it is definitely later in the forecast, but there’s a gem right at the start if you’re quick.
Tuesday morning (21 July) is our first real chance. Explosivos is seeing a clean 4 ft swell from the SW, with a nice long 12-second period. The wind is a light cross-on from the SSW at 10 km/h, so it’s not perfect, but it’s workable. The water is a balmy 71°, which is a whopping 8° warmer than usual for this time of year – that’s very unusual, and it’s a real treat. The combined wave energy is moderate at 533. It’s not the best session of the month, but it’s a start.
Wednesday morning (22 July) is a total standout. Glassy conditions with a 4 ft swell from the south. The wind is a dead calm from the SW at just 5 km/h. The catch is the period is short – only 7 seconds – so it’ll be a bit soft and choppy, but when it’s that clean, you don’t complain. The energy is moderate (441). This is the best morning of the first week, no question.
The rest of the week through to Sunday morning (26 July) is a bit of a grind. The swell stays small, around 2 ft to 3 ft, with mostly cross-onshore winds. The energy jumps up to 1016 on Sunday morning, but it’s messy. Not worth paddling out for.
Monday 27 July through to Thursday 30 July sees the swell pick up to 5 ft to 5 ft, and the period is long, dropping from 17 seconds down to 13 seconds. This is proper groundswell. The energy is strong, hitting 1303 on Monday morning and 1409 on Monday afternoon. But here’s the problem: the wind is cross or cross-onshore from the S or SSW at 10 to 15 km/h. It’s going to be bumpy. For a more experienced surfer, the size and power are there, but the conditions won’t be clean. This is a “check the cams before you go” situation.
Friday 31 July is another absolute beauty. The morning is glassy with a 4 ft SW swell at 12 seconds. The wind is a light 5 km/h from the SW, dead offshore. The energy is moderate (456). Then in the afternoon, it goes completely flat calm – 0 km/h wind, glassy, with a 3 ft swell. If you can get out on Friday, you’ll be smiling. This is the second standout of the whole outlook.
The surf then drops off into the first week of August, with small 3 ft to 3 ft swells and persistent cross-onshore winds. Not much to write home about.
Now, the real big one is on Wednesday 5 August. Explosivos is looking at a 6 ft to 7 ft swell from the SW, with a 15-second period. The combined energy is a massive 1753 – that’s very strong wave energy. This is a serious swell. For a sandbar, that’s going to be powerful and heavy. The wind is a light cross-on from the SW at 10 km/h, rising to 15 km/h in the afternoon. This is for advanced surfers only. It’s too big for beginners, and at 7 ft, it’s pushing into expert territory. The long period means it’ll be a bit walled-up at the beach, but there’ll be some bombs. This is the biggest, most powerful swell of the entire 16 days.
Overview: Wednesday the 22nd morning is your clean, fun session. Friday the 31st is your glassy, clean session. And Wednesday the 5th of August is the big, powerful one for the experienced crew. Tuesday morning (21st) is a decent fallback.
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.
