The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for La Arena over the next couple of weeks.
Honestly, it's a bit of a slow burn. We're in for a long stretch of small, messy surf starting right now. From Friday the 17th through the end of the following week, most of the days are just not worth paddling out for. The swell is tiny, often under 2ft, and the wind is mostly onshore or cross-onshore, making it a real chop-fest. You'll see some energy building around Monday the 20th, with the combined swell energy hitting 124 (moderate), but it's still coming from a poor direction with a short period, so it won't be any good. This poor run carries on through the 25th and 26th, with a bit more size on the 26th (5ft) but rain and onshore winds ruin it.
The one bright spot, and the true standout, is a window on Monday the 27th of July. For the morning session, the stars finally align. We've got a clean 4ft swell from the NNW, and the wind is glassy—dead calm. That's a major positive. The wave energy is pumping, with a combined energy of 332 (strong), which means there's some proper push behind it. The period is 10 seconds, so it's a decent groundswell with some good shape. This is the morning to be in the water. La Arena is a beginner-friendly break, and with 4ft, it's approachable for confident learners and a fun size for everyone else. The water is a very unusual 74°, which is much warmer than normal for this time of year.
After that, it drops back off. Tuesday the 28th has a clean morning with some cross-offshore wind, but the swell drops to 3ft. The energy is moderate (126), but it's just not the same quality as the day before. The end of the month and into August 1st sees a bigger, more powerful swell (up to 4ft from the NW with periods of 10-11 seconds and combined energy up to 387), but the wind is onshore or cross-onshore, so it's going to be a messy, choppy affair. Not one for the paddle board.
So, to sum it up: don't hold your breath until Monday the 27th. That's your one morning of magic. Everything else is a write-off.
Rusty.

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