The Lowdown
Alright, let’s cut through it. Banzai – a proper reef break – and the next 16 days are mostly a bust. We’re talking a long stretch of onshore junk.
Water temp is 85°, pretty normal for this time of year. Nothing to blame for this slop.
Kickin’ off Sunday, August 30th, with tiny, weak swell – maybe 3ft out of the ESE. Energy is weak (84). That NE wind at 9 mph blowing cross-shore just messes up any clean face. No good.
Monday the 31st and Tuesday September 1st are the same sad story. Stormy skies, onshore wind at 9-12 mph. The swell is small, energy barely cracks 100. All SE wind slop. Write it off.
Wednesday the 2nd and Thursday the 3rd of September: swell gets to 4ft on Wednesday morning, energy hits 201. Wind is cross-onshore, light breeze at 6 mph puts a texture on it. It’s not clean. Thursday is 4ft, same kind of bumpy cross-onshore crud.
Friday the 4th through Tuesday the 8th of September is a dead zone. Swell drops back to 3-3ft, energy in the 40s, 50s, 80s. Onshore winds the whole way. Just flat and choppy.
Then we get a spark. Wednesday September 9th: 7ft of ESE swell, period up to 8 seconds, energy jumps to 838. The wind is cross-shore from the NE at 12 mph. It’s a bit raw, a bit messy – marginal is the word. Over 5ft, this is for the experts only, especially at a reef.
Thursday the 10th of September: another 7ft ESE pulse, energy at 886, and the wind swings to E at a light 6 mph – light cross-onshore. It’ll be lumpy, but more makeable. The afternoon goes onshore and drops to 5ft, so that morning is the play.
The second week is a total fizzle. From Friday the 11th to Monday the 14th of September, it’s tiny again – 2ft to 4ft max, low energy, onshore winds. Nothing to chase.
Your only real shot is the 9th and the morning of the 10th of September. The 10th morning is the pick – 7ft, decent energy, light breeze keeping it from getting totally wrecked. But don’t expect perfection. You’ll work for your waves.
Yeah, it’s a rough run, but that’s how it goes sometimes. Forecasts can change, and when it’s on, Banzai is worth the wait.

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.
