Alright, Rusty here. Let’s talk about what’s on offer.

Right now, and looking out over the next two and a half weeks, we’re staring at a big, flat, frustrating stretch of nothing worth paddling out for. The first solid recommendation doesn't pop up until quite a ways out. After some blank days with no surf to speak of, the first real glimmer arrives on Thursday, July 17th.

So, here’s the deal for 21st Street (Miami): The first chunk of the forecast is a tough one. From Thursday, July 2nd through Wednesday, July 16th, there is zero quality surf to recommend. We’re looking at tiny waves – mostly below 2.5 ft – coming from the northeast or southeast with short, weak periods around 4 to 8 seconds. The winds are nearly always cross, onshore, or cross-onshore, creating choppy, ugly surf. The combined energy during this period is very low, with values like 53 (weak energy) or even down to single digits. It’s a complete write-off for a paddle surfer.

However, things finally change on Thursday morning, July 17th. The swell starts to build, hitting about 4.3 ft from the east, with a period of 6 seconds. The combined swell energy rises to 105, which is moderate wave energy. The wind turns onshore from the east at 16 mph, so it won't be glassy. The conditions are still listed as poor surf, but this is the first time in two weeks we get some actual size and push. It’s a one-meter-plus day in feet.

Friday, July 17th holds similar. The swell stays around 4.3 ft from the east, with the period holding at 6 seconds. The combined energy is 106 (moderate). The wind is stronger, 16 mph from the east-northeast, and onshore. The waves will be raw and bumpy.

While I’d usually call the best of this a stand-out beginner day due to the size, the onshore wind chops up the surface. The water temp is 30.3°, about 1.2° warmer than average for this time of year, which is a touch warmer than normal. Expect the usual crowds at this spot, especially after such a long flat spell, crowds are often here.

That’s about it. A long, quiet wait until a late-week pulse of east swell. Hang in there.

Information about the 21st Street (Miami) Surf forecast

The above surf forecast table for 21st Street (Miami) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 21st Street (Miami) can be found by selecting the local surf guide option on the grey menu. Our 21st Street (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 (21st Street (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 21st Street (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.

21st Street (Miami) is 1 km (1 miles) from the city of Miami Beach. If you plan a vacation in South Florida, look for hotels and other accommodation in Miami Beach. Miami Beach has rooms for a wide range of budgets as well as car hire and transport links.
