The Lowdown
Alright, Rusty here again. Let’s talk about what’s coming for our local break.
Honestly, this 16-day outlook is a total dud. From Sunday, September 13, all the way through Monday, September 28, every single session is marked as poor surf conditions with a score of zero. There’s not one recommendation to paddle out. It’s a blank run, plain and simple.
We kick off Sunday morning with a 1.6m swell from the ESE, a short 8-second period, and a cross-onshore wind from the SE at 25 km/h. The combined swell energy is weak at 277. It’s choppy and messy. Monday and Tuesday are more of the same—1.4m to 1.5m waves, cross-onshore, short period, and low energy (226–285). Wednesday the wind goes onshore, but it’s still poor with 1.3m to 1.4m.
Thursday, September 17, afternoon sees a 1.5m, 11-second groundswell from the ESE and energy jumps to 502—that’s moderate to strong energy. But the wind is cross-onshore, so it’s still poor. Friday and the weekend bring 1.6m to 1.7m waves, but with short periods and cross-onshore winds, it’s just messy. Energy sits in the 245–314 range.
In the second week, around September 22, we get a 2.0m swell Tuesday morning, but with a short 7-second period and cross-onshore winds, that’s too big and ugly. Energy is 354. On September 23, the afternoon has a 1.6m, 12-second long-period groundswell from the ESE and energy of 802—that’s strong. But again, cross-onshore winds kill it. Even the onshore days later, like September 24 with 1.3m and 11-second period and energy 408, get a poor rating.
It’s all poor through September 28. Water temp on the first day is 27°C, about average.
So, there’s no surf to speak of. This is one of those stretches where you just leave the board at home. Forecasts can change, but for now, it’s a no-go.
Rusty.

Information about the Miami Surf forecast
The above surf forecast table for Miami provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Miami can be found by selecting the local surf guide option on the grey menu. Our Miami 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 (Miami) 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 Miami 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.
Miami is 8 km (5 miles) from the city of Natal. If you plan a holiday in Rio Grande Do Norte, look for hotels and other accommodation in Natal. Natal has rooms for a wide range of budgets as well as car hire and transport links.
