The Lowdown
Alright, Rusty here again, let’s talk about the same stretch in feet and miles.
The first few days are a slow start, with weak energy and messy cross-onshore breezes. The water’s about normal for the season.
We start to see some life on Thursday the 23rd. A long period groundswell from the SW, 24 seconds, shows up. That’s a proper long-period groundswell, which will be a bit straight for a sandbar, but the energy is moderate (776). The morning with a light offshore breeze is the only time to look at it. The swell is tiny, only 2ft, but that period will give it a bit of push.
The big winner, the one you don’t want to miss, is the stretch from the 27th of July through the 30th. The swell builds to a solid head-high plus, hitting 1.6m to 1.9m (5 to 6ft) from the SW, with a period of 14 to 16 seconds. The energy is strong (1441 on the 27th afternoon). The wind is light, mostly cross-onshore, but the 29th morning is the cleanest with barely a breath of air. That morning you’ve got a 6ft SW swell at 14 seconds, and the energy is pumping at 1481. That’s your best bet. This is an advanced wave, so don’t send the groms out there.
After that, the swell fades into early August. The 2nd of August has a huge energy spike (1996) with a 6ft SSW swell, but the wind is more onshore, killing the quality. The 4th of August brings a shorter period windswell, not worth chasing.
The call is the morning of the 29th of July. Clean, head-high plus, powerful SW groundswell at Explosivos. It’s an advanced break and crowds are a possibility, so get there early.
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.
