The Lowdown
Alright, boys and girls, Rusty here, and I’m going to lay it out plain for Miami. The next 16 days are a real bummer for surf. The swell is showing up, but the wind is a total buzzkill. We’re looking at a solid run of onshore wind that’s just ruining the wave quality. There’s a gap right at the start with no real recommendation, but the swell is there, it’s just the wind that’s the problem.
We start on Monday, July 20th, at Miami (beach and reef). The swell is a solid 7ft from the ESE with a short period of 8 seconds, pushing a moderate 616 of combined energy. The water is 81°, about average for the time of year. But the wind is blowing from the SE at 15 mph, a cross-on breeze that’s just tearing the surface up. It’s choppy and messy. This is the story for the whole first week – the swell sticks around between 4ft and 7ft, but the wind is always cross-on from the SE or ESE, ranging from 6 to 15 mph. The energy starts moderate and drops to weak by the 27th (95 on the energy scale). The period is short, mostly 7 to 9 seconds, so it’s all wind-swell, no real punch. Thursday the 23rd and Friday the 24th have a bit of rain, but the wind is still light to gentle, so the surf is small and grovelly. It’s all marked as “poor surf conditions.” Honestly, this looks more interesting for a kite surfer than a paddle surfer with that persistent cross-on wind.
The second week is pretty much the same story. From the 28th of July through the 4th of August, the swell picks up again, especially towards the end. August 1st has a 6ft ESE swell, building to 7ft from the SE by the 2nd, with moderate energy reaching 523. But the wind stays stubbornly from the SE at 12-15 mph, cross-on, keeping things choppy. The period is still short, 6 to 8 seconds. There’s a small window on the 30th and 31st of July where the wind turns more onshore from the E and ESE, but it’s still not clean, and the swell is weak at 4ft to 4ft. Nothing here is a standout. The best offer is just a matter of picking the least bad day, but I can’t in good conscience call any of them good.
So, here’s the deal: if you’ve got a kite, the wind is consistent. For a surfboard, you’re better off waiting for a shift in the forecast, because this is a long stretch of onshore, choppy, poor-quality surf. The only thing that changes is the size of the mess.
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.
