The Lowdown

Alright, Rusty here again. Let’s break down the Banzai forecast in feet and miles.

It’s a pretty quiet run for the next couple of weeks. The wind is mostly onshore or cross-onshore, and the swell is never really hitting the sweet spot for this break. The water temp is about average for the time of year, but that’s about the only thing that’s normal.

The forecast starts off slow. From Thursday the 20th of August right through until the end of the month, we’re looking at a lot of poor surf conditions. The swell is small, mostly under 5ft, but the wind is blowing straight onshore from the ESE or SE, making everything messy. The wave energy is weak to moderate at best, in the 34 to 485 range, and the period is short, around 5 to 8 seconds, so it’s not going to have any power. Not worth getting wet.

There is a tiny window late on Monday the 31st of August. The wind goes glassy, light from the SSW, and the swell drops to around 3ft from the ESE with a period of 8 seconds, and the energy is 104. It’s surfable, but just barely. The conditions are described as ordinary, so don’t get your hopes up. It’s a quick window of clean-ish water, but the swell is tiny.

Then we hit a gap where there’s basically nothing. The first few days of September are poor again, with onshore winds and small, weak swell.

Finally, Wednesday the 2nd of September morning shows a bit of a pulse. Swell from the SE at around 6ft, period 8 seconds, and energy of 355. That’s a moderate energy, but the wind is light from the SE, which is onshore. The forecast says it’s marginal. This is a bigger swell, but it’s not clean, and the direction is from the SE, which is not the optimum S direction for this reef. It’s for the more experienced crew only, as it’s over 5ft.

So, to be straight with you, there’s no standout session in this 16-day window. The cleanest, most promising moment is that glassy period on the 31st of August, but the swell is tiny. It’s a lean stretch. Hang tight, lads.

Rusty.

Information about the Banzai Surf forecast

The above surf forecast table for Banzai provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Banzai can be found by selecting the local surf guide option on the grey menu. Our Banzai 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 (Banzai) 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 Banzai 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.

Banzai is 2 km (1 miles) from the city of Boca Chica. If you plan a holiday in Caribbean Coast - Dominican Republic, look for hotels and other accommodation in Boca Chica. Boca Chica has rooms for a wide range of budgets as well as car hire and transport links.
