The Lowdown
Right then, let's have a look at what Baleal Sul's got cooking for us over the next couple of weeks.
Honestly, it's a bit of a tough stretch ahead. The ocean’s got some energy, sure, but the wind just won't play nice and the conditions look messy more often than not. There are a couple of potential windows where things line up, but you'll need to be patient.
The week starts off on a rough note. Sunday the 23rd, we've got a 5ft swell from the WNW with a fresh 19 mph SSE wind blowing offshore. It’s clean but the overall energy is moderate (642) and the water's sitting at 65°, which is a bit colder than normal for this time of year. A morning session might be worth a look, but the tide or something else is making it marginal. Afternoon turns into a risk of thunderstorms with the wind shifting, so no dice there.
Monday the 24th and pretty much the rest of that week into the next is a write-off. The wind is either cross, cross-off, or onshore, chopping everything up. The swell hangs around, but it's not clean.
Now, keep your eyes peeled for Friday morning the 28th. That's the one that could be special, if the wind and tide gods are smiling. We’re looking at a 8ft swell from the NW with a long 11-second period. The combined wave energy is massive (1542). But here’s the rub: the wind is light and blowing onshore. If that backs off to glass or goes offshore, Baleal Sul (Portugal) could get some serious, powerful lines. This one is for the experts only at that size—too big for beginners.
The following week, from the 30th of August through to the 7th of September, is a real bummer. The swell drops off and then builds again, but it's constantly plagued by cross-onshore or onshore winds. The waves are there, but they'll be a choppy, blown-out mess.
Even the big pulses around the 6th and 7th of September, with 8ft to 8ft swell and over 2000 in wave energy, come with strong onshore winds. That setup looks way more interesting for kite surfing than paddle surfing.
So, the standout window is that Friday morning, 28th of August. If it cleans up, it’s the best on offer. Otherwise, it’s a waiting game for the wind to sort itself out.
