The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Miami over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a rough stretch. Don’t get your hopes up. We’re looking at a solid 16-day window with nothing but “poor surf conditions” on every single forecast. That’s a big fat zero from the data, and that’s what we’re working with.
The first bit of the run, starting Friday the 17th, is all about that cross-onshore wind. We’ve got a moderate breeze from the Southeast at 15 mph, and it’s just chopping everything up. The swell is there, but it’s messy. Friday afternoon we’ve got a 7 ft swell from the SE, period at 7 seconds, and 408 units of combined energy – that’s a moderate amount of energy, but it’s wasted on the wind. Saturday the 18th is bigger, 8 ft to 8 ft, energy climbing to 585 and then 949 (moderate to strong), but the wind is still cross-on and the wave comment says it all: poor. For a beginner, that 8 ft is too much on a bad day. Sunday the 19th through to the end of July is more of the same. The swell drops a bit, but the wind stays on it, or we get rain and thunderstorms. The water temp is around 81°F, which is about normal for the time of year, so at least it’s warm while you’re getting frustrated.
We go through a whole week of this. The wind eases to a gentle breeze around the 24th and 25th, but the swell drops to 4 ft to 5 ft, and it’s still cross-onshore. The energy falls off to the low 200s and then into the 100s – weak wave energy. The period drops to 7 seconds or even 5 seconds later on, which is just short-period chop. There’s nothing to get excited about.
For the first week of August, it’s the same story. The wind picks up again to a moderate breeze, the swell is weak, and the period is short. It’s a total blank run. If you’ve got a kite, this setup might be more interesting for you than for a paddle surfer, because the wind is consistent and the waves are poor. But for a surfboard? I’d leave it on the beach.
Honestly, there’s no standout day here. Not a single one. This is just one of those stretches where the forecasts are empty, and we’ve got to wait for things to change. It’s a bit of a bummer, but it happens.
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.
