Table - best surf conditions forecast for Praia das Macas over the next 16 days.
Alright, Rusty here. Let’s have a look at what we’ve got on the cards for Praia das Macas.
Honestly, friend, this is a tough run. The whole 16-day window is pretty much a write-off for decent waves. You're looking at a big, long gap from now all the way through to the end of the forecast. Not a single session gets a tick from me. Every entry is marked "poor surf conditions" with a score of zero, so there's nothing to get excited about.
Over the next week or so, we see a bit of swell pushing in, but it's all messed up by the wind. From Tuesday morning, 7th July, we’ve got a tiny 2ft NW swell with a short 5-second period, but the wind is a cross-onshore breeze at 12 mph, just making a mess of things. The combined swell energy is weak at (39). That pattern sticks around. Wednesday and Thursday see the swell bump up a touch, with some 3ft NW/NNW swell on Wednesday, but the cross-onshore and cross-shore winds chop it all up. Even when the swell period stretches to 10 seconds on Thursday morning, the wind is still cross-on, keeping it lumpy. The combined energy creeps up to (101) on Thursday afternoon, but it's still ugly out there.
Friday and Saturday don’t offer any relief. The swell drops back to 2ft and 1ft, and the wind remains cross-onshore. Saturday afternoon does see a long-period 11-second WNW swell, but it’s only 2ft, and with a moderate cross-onshore breeze, it’s not doing anything for us.
Into the second week, from Sunday 12th July onward, the swell stays small and weak. We see some NW swell around 2ft to 3ft, but the period is short, between 5 and 9 seconds, and the wind stays onshore or cross-onshore. The combined energy hits (148) on Monday 13th July afternoon with a 3ft NW swell, but the wind is onshore at 9 mph. It’s just not going to be any good. From Thursday 16th July to the end, the swell hangs around 3ft to 4ft, but the wind is up to 22 mph from the NNW, making it fresh, lumpy, and totally unrideable for a paddle board. Honestly, with that much wind and a beach setup, a kite surfer might find it more interesting than we will.
This is a consistent break in terms of how often it breaks, but when the conditions stay poor for this long, it’s just a flat spell for us. The water temp is 67°F, which is about average for this time of year, so at least the water’s not a shock.
Sorry there’s no good news, folks. This one’s a skip.
Rusty.
