The Lowdown
Alright, Rusty here. Let's be real about the next 16 days for Miami. There's not a single session worth paddling out for. The forecast flags every single one as "poor surf conditions," and the wind is just a constant problem – cross-onshore, lumpy, and ugly. It starts on Friday, the 4th of September, with a 5 ft swell from the ESE, a 9-second period, and a 12 mph cross-onshore breeze. The combined energy is a weak 315, and it's all wrong. That sets the tone for the whole stretch.
The water temp is 81°, which is about normal for this time of year, so at least the water's warm while you're getting skunked.
We get a couple of days where the wind turns onshore, like Sunday the 6th and Monday the 7th, but the swell drops to 4 ft to 4 ft with a short period of 8 seconds and the energy is weak (176, 175). That's not surf, that's just bumpy water.
The biggest swell comes through around the 12th of September, with 7 ft from the east and an 8-second period. The energy climbs to 541, which is moderate, but the wind is onshore at 15 mph, and it's still "poor surf conditions." That's a write-off. For a beach-and-reef setup like Miami, with that much wind and a messy swell, this looks a lot more like a kite surfing day than a paddle surfing day.
The rest of the week into the second week is more of the same: 5 ft to 6 ft swells, periods of 8 to 9 seconds, and cross-onshore or onshore wind. The energy gets up there, hitting 491 on the 19th of September, but the wind and the "poor" tag don't change. There's nothing to get excited about. The whole 16-day forecast is a blank. It's a rough stretch, but it happens. Forecasts can turn, but for now, leave the board at home.
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.
