Table - best surf conditions forecast for Biologia (Mar del Plata) over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks down at Biologia.
The outlook starts with a bit of a damp squib to be honest. The first solid recommendation I can give you doesn’t come until Sunday morning the 12th of July. Up until then, it’s a mess of poor conditions and small, messy swell. Wednesday the 8th and Thursday the 9th have a bit of energy in the water, but the wind is all over the shop and the quality just isn’t there.
Sunday morning the 12th of July is where we get our first real chance. It’s an early call. The swell is from the ESE at around 3 ft, with a clean 13-second period. The real draw here is the wind – a solid offshore from the W at 12 mph. That’ll have the waves at Biologia (Mar del Plata) looking clean. The combined swell energy is moderate (253). The water is sitting at 50°, which is about average for this time of year. There's not much to get excited about aside from the clean conditions, but it's a solid, if small, option for a morning session.
The best bet in the whole run looks like it’s shaping up for Saturday afternoon the 18th of July. The data is pointing to a fun window. Swell pushes in from the E at 4 ft, with a 10-second period. The wind swings to a cross-off from the SW at 9 mph, keeping things clean. The combined wave energy is strong (524). This is the standout. Crowds are reported as ‘sometimes’ here, so you can expect a few others out, but with that clean, punchy E swell, this is the one to pencil in for a proper surf.
The run closes out with a few ‘marginal’ days. Tuesday morning the 21st of July has a nice 5 ft swell from the ESE and a clean offshore wind from the WNW at 16 mph. It’s a bit bigger, but at 9 seconds the period is short, making it a bit lumpy and less organised. A kite surfer might have more fun with that raw energy. The energy is moderate (351). The following days on the 22nd are similar, with clean winds but a drop in swell quality.
Honestly, it’s a lean month for Biologia. A lot of poor days in between a couple of windows that are worth chasing. The 18th of July is your best shot.
