The Lowdown
G’day, I’m Rusty. Let’s break it down.
So, for Explosivos (sandbar) over the next 16 days, we’ve got a steady pulse of southwest groundswell coming through, but the wind is mostly cross-onshore, so the waves are gonna be a bit bumpy. The scores reflect that—marginal most days. Still, there’s some decent energy, and a couple windows where it’s worth grabbing your board.
It starts on Wednesday, August 5th. Morning has 1.2m SW swell at 13 seconds, with a light onshore breeze and clean-looking conditions. Water temp is 21°, which is 5° warmer than usual—that’s a big anomaly, so you’ll be in boardies. Combined energy is 698 (moderate). Not a classic day, but a paddle.
Thursday the 6th picks up. Morning is 1.0m at 17 seconds—long period groundswell, 970 energy. Afternoon jumps to 1.6m SW at 16 seconds, combined energy 1350 (moderate to strong). Still cross-onshore, so a bit of chop, but those long-period sets will have some grunt. This is one of the better days—especially for a point or reef.
Friday the 7th stays at 1.4m, 14 seconds, 975 energy. Saturday the 8th drops to 1.0m and 0.9m. Sunday the 9th is the worst—0.7m and 0.9m, barely breaking.
Monday the 10th rebounds: 1.3m SSw at 14 seconds, 1173 energy morning, 1143 arvo. Tuesday the 11th has 1.6m arvo with cross-shore wind—slightly cleaner, 1005 energy. Wednesday the 12th is smaller.
Thursday the 13th is another high point: 1.3m SW at 18 seconds in the arvo—very long period, combined energy 1437. Strong but cross-onshore. On a sandbar, that long period can make it fat, but reef hunters will love it.
Friday the 14th holds at 1.4m, 16 seconds, 1263 energy. Weekend is mellow, 1 to 1.3m.
Then from Monday the 17th it builds. The real standout is Wednesday the 19th and Thursday the 20th. Wednesday morning has 1.7m SW at 17 seconds—combined energy 1991 (strong). Afternoon is 1.9m at 16 seconds, 1967 energy. Thursday the 20th is 1.8m at 16 seconds, 1792 energy. This is the best stretch of the whole forecast—big, powerful SW groundswell, but the wind stays cross-onshore. Good for strong surfers, but bumpy. Still, if you want size, this is it.
No glassy days, but the 19th and 20th are the ones to pencil in.
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.
