Overall Pattern (Imperial)
Alright, crew, let’s talk about Prainha. The next 16 days start off real quiet, but there’s a couple of sessions hiding in the second week that are worth getting out of bed for.
The Details
This Friday, 3rd July, is a total washout. The swell is 4ft from the SE, but it’s a weak 7-second period, and the wind is a messy cross-shore from the SSE at 16 mph. The energy is weak. Don’t even bother.
The whole first week is a flat spell. Swell is mostly below 2ft. Water temp is 65°F, which is about average for this time of year. There’s a couple of glassy mornings on Sunday 5th and Monday 6th, but with only 2ft of swell, it’s just not enough.
The first real standout is the morning of Sunday, 12th July. The wind goes light offshore from the WSW at 3 mph, and we get a 3ft swell from the ESE with a nice, long 13-second period. The energy is moderate (264). That’s a groundswell, and with that offshore wind, it’ll be the cleanest and best-shaped wave of the whole forecast.
The other one to watch is the morning of Saturday, 18th July. The swell picks up to 5ft from the SSE with a 10-second period. The wind is a strong cross-offshore from the SW at 12 mph, keeping it clean. The energy is a solid 488. This is a powerful one, but it’s over a week away, so don’t book the day off just yet. It’s getting a bit big for beginners, but for the experienced lot, it’ll be fun.
Bottom Line
Prainha is usually a reliable spot, but this forecast is a quiet one. The first week is a bust. The best chance of a wave is the Sunday morning, 12th July, with the offshore wind and long-period groundswell. The Saturday, 18th July is a good backup if you’re patient. Keep your eyes on the wind and the clean days.

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