The Lowdown
Alright, folks, it’s Rusty here. Let’s be straight with you – across the entire 16-day window, conditions are pretty grim for paddling out at Miami. It’s a real bumpy, choppy mess from start to finish, and honestly, I wouldn’t bother getting wet.
The first solid chance at any surf comes Monday the 7th, but it’s not surf you want. We’re looking at a cross-onshore wind from the ESE, blowing at 12 mph, chopping up what little there is. Swell is running around 4 ft from the ESE with a short-period 8 seconds, and the combined energy is a moderate 182 – but it’s just poor. The water temp is about average, sitting at 81°.
This pattern just repeats day after day. The wind stays cross-on or directly onshore, mostly from the SE and ESE at 12 to 16 mph. Swell heights bob around between 4 ft and up to 7 ft by the afternoon of Tuesday the 22nd, with the combined energy peaking around 417 on Thursday the 10th, then again at 395 on the 22nd. But it’s all chopped slop with a period that barely creeps over 8 seconds.
Forget about clean waves. Even when the swell period stretches to 8 seconds, the wind just wrecks it. The setup at Miami is a beach and reef break, but with this constant onshore breeze, it looks a lot more interesting for windsurfing or kiting than surfing. There is no standout session. No day to get excited about. It’s a long, blank run of poor surf.
Stay patient. It never stays this bad forever.
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.
