The Lowdown
Hey everyone, Rusty here. Let's have an honest look at what's coming up for the Plentzia region. Gotta be straight with you – this stretch from now through the middle of August looks pretty quiet, but there is a little light at the end of the tunnel for the last week of the month.
Looking at the overall pattern, we're in a long, flat spell to kick things off. For nearly the first week and a half, from Thursday 13th August all the way through to Saturday 22nd August, it's basically a no-go. The swell is tiny – we're talking waves around 1ft to 4ft at best, with weak combined energy between 44 and 130. The wind is almost always onshore or cross-onshore, making things choppy and messy. Even the few glassy mornings, like Tuesday 18th August and Wednesday 19th August, have just tiny 2ft to 1ft waves with low energy (45 and 10). That's not worth paddling out for. It's more of a kite-surfing setup than anything for a surfboard, especially on Saturday 15th afternoon when a 3ft NNW swell hits with cross-onshore winds.
Then things start to change slightly. On Sunday 23rd August, the morning brings glassy conditions with a 3ft swell (energy 96) out of the NW – it's "surfable but very ordinary" as the data says. The afternoon cleans up with a light cross-offshore NE breeze and a 5ft NW swell (energy 188). Still not epic, but it's the first real sign of life.
Now, here's where it gets interesting. The standout period is Monday 24th and Tuesday 25th of August. On Monday morning, we see a jump to a 8ft NW swell, but the combined energy is a strong 811, and wind is onshore from the WNW, which is a problem. It's only for experts if anyone dares, as it's bordering on too big for most. But hold on – Tuesday 25th August morning is the real gem. We get a 5ft NW groundswell with a 9-second period under glassy, calm conditions. The energy is a moderate 304, the water temperature is a very unusual 75°F – that's a massive 4°F warmer than normal for this time of year, making it feel like a bath. The break at Plentzia is a sheltered spot that needs WNW swell, and this NW swell is close enough. For a sheltered break that rarely breaks, having clean, glassy 5ft waves is a chance you don't want to miss. The afternoon on Tuesday follows up with clean 4ft NW swell and cross-offshore NE winds (energy 244). Crowds? Plentzia can get busy, so expect some company.
After that, it fades again from Wednesday 26th onwards with smaller, onshore slop, though Friday 28th morning offers another glassy window with a 2ft WNW swell (energy 87) – surfable but very ordinary.
So, the long and short of it: the first week is dead. Hang tight. The best of the window is unquestionably Tuesday 25th August morning at Plentzia, with clean, glassy head-high waves and warm water. It's promising, but still a week and a half away, so stay flexible. That's your call.
Rusty.

Information about the Plentzia Surf forecast
The above surf forecast table for Plentzia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Plentzia can be found by selecting the local surf guide option on the grey menu. Our Plentzia 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 (Plentzia) 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 Plentzia 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.
Plentzia is 8 km (5 miles) from the city of Getxo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Getxo. Getxo has rooms for a wide range of budgets as well as car hire and transport links.
