The Lowdown
Right, let’s have a look at what we’ve got for Sandy Beach (Barbados). This is a beach and reef setup, exposed, and it wants ESE swell. The problem from the start to mid-month is the wind – it’s hammering out of the ENE at 25 mph, sometimes 28 mph, and it’s cross or cross-on. That is going to leave it choppy, messy, and basically not surfable. The water temp is sitting at 81°, which is bang on normal for this time of year, so no surprises there.
The first few days are a total write-off. Wednesday the 2nd to Friday the 4th of September, we’ve got solid swell height sitting around 7 ft to 8 ft, but that ENE cross-shore at 25–28 mph just wrecks it. The combined energy is moderate to strong (975–1215), but with that wind, it’s just a washing machine. Not a single score above a 0.
The weekend of the 5th and 6th is where we start to see a glimmer. The wind drops a notch to 19 mph, still cross, but the swell gets longer – up to 13 seconds on the Saturday and Sunday – and the energy climbs to strong (1975–2196). The surf is a chunky 7 ft to 7 ft. It’s still lumpy and cross-chop, but it’s teetering on the edge of workable. The scores are only a 1, so it’s very marginal. If you are an expert and can handle a bit of bump, you might get a few, but for most of us, it’s a pass.
Then Monday the 7th, the swell peaks at 8 ft with a period of 13 seconds, and the combined energy is very strong at 2504. But the wind swings cross-on at 16 mph and flips between onshore the next day. It turns into a messy, choppy beast. That is expert territory only, and even then, it won’t be clean.
The middle of the week, the 9th to the 11th, the swell drops back to 5 ft to 6 ft, but the wind stays cross or cross-on at 16–22 mph, so it’s still poor.
Now, there is a long gap of really poor conditions until the 15th of September, a Tuesday morning. We get a tiny 2 ft swell from the SSW, but the period is a massive 21 seconds – that is a very long-period groundswell. The combined energy is moderate (603). For a beach break like Sandy, a 21-second period can make it break too straight, but it is a reef setup and might line up. The wind is cross at 12 mph, which is still not ideal, but it’s the only day that even gets a marginal 1 rating. It is a long shot.
The 16th and 17th bring SSW swells again, 3 ft, with periods from 19 down to 16 seconds, and the cross-on wind makes it choppy. The energy is moderate (836–964), but the conditions are just average at best.
The best on offer? Honestly, this is a rough run. The standout is the morning of Saturday the 5th of September, with 7 ft of ENE swell at 13 seconds, but the 19 mph cross-shore is a killer. If you are a kite surfer, this entire period is more interesting than for a surfer. The second best is the 15th of September, but that 2 ft at 21 seconds is a real gamble for the patient local.
Overall, I wouldn't recommend paddling out here for the next 16 days. The wind just won't let up. Keep an eye on it – things can change, and a drop in wind could make a big difference.

Information about the Sandy Beach Surf forecast
The above surf forecast table for Sandy Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandy Beach can be found by selecting the local surf guide option on the grey menu. Our Sandy Beach 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 (Sandy Beach) 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 Sandy Beach 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.
Sandy's Beach is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
