The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Casa Grande.
We’ve got some solid swell making its way in, but it’s a bit of a mixed bag for the first few days. The real issue is that the initial pulse is a bit too much of a good thing. The energy is pumping, with a combined energy reading of 589, but those waves are coming in at 7ft to 8ft from the NE. That’s a lot of water for a sandbar, and with a period of only 7 to 8 seconds, it’s going to be a bit of a washing machine. The wind is light and cross to cross-onshore, which doesn’t help clean it up. This is more of a big-wave session for the experienced crew only, and honestly, it looks a bit more interesting for kite surfing than a proper paddle session.
The water temp is sitting pretty at 84°, right on the money for this time of year, so no need for a steamer.
Come Thursday (27th August) morning, the swell holds at 7ft, but the wind picks up a bit, making it choppy. Not great. That theme continues into Friday and Saturday (28th & 29th August), where the swell drops to 5ft – 5ft, but the conditions are just marginal. The energy is dropping, too, hanging around the 250 to 277 mark. It’s surfable if you’re desperate, but nothing to write home about.
We hit a bit of a lull from Sunday (30th August) through to Tuesday (1st September). The swell drops right off to 3ft on Tuesday, and while we get some glassy conditions on the 1st of September, the wave energy is weak, under 100. It’s just small and ordinary.
The best of the whole outlook, and the only real standout, looks like it’s shaping up for Wednesday the 10th of September. The swell picks up again to around 6ft from the NE with a moderate energy reading of 403. The wind is forecast to be calm and glassy in the afternoon. That’s a rare treat. The waves are still a bit on the bigger side, but with zero wind, it’s going to be clean and lined up. This is the window to circle on the calendar. Just keep in mind, since it’s a couple of weeks out, the forecast could shift a bit.
Before that, the 9th of September afternoon also shows promise with 5ft swell and glassy conditions, but the energy is a fair bit lower at 285. It’s a decent option, but the 10th is the real winner.
Rusty.

Information about the Casa Grande Surf forecast
The above surf forecast table for Casa Grande provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Casa Grande can be found by selecting the local surf guide option on the grey menu. Our Casa Grande 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 (Casa Grande) 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 Casa Grande 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.
Casa Grande is 34 km (21 miles) from the city of Santa Marta. If you plan a holiday in Caribbean Coast, look for hotels and other accommodation in Santa Marta. Santa Marta has rooms for a wide range of budgets as well as car hire and transport links.
