The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, I’ll be straight with you – this is a tough run for Cogumelo. The swell is small and weak, and the wind is mostly a mess from the wrong angles. There’s a small window early on, but nothing that will get you frothing big time.
Tuesday morning, the 14th of July, is the only real look we have for a while. The swell is a tiny 2ft from the NW, with a period of 7 seconds – not much push, but the wind is glassy. That’s a major plus. Clean, smooth conditions will make the most of the weak energy. The combined energy is only 88 (weak), so don’t expect any power, but it’s the only time the wind plays nice. This is the standout, but only because everything else is rough.
After that, it’s a long stretch of poor surf. From Tuesday afternoon right through to the end of the month, the wind is mostly cross-on or onshore, and the swell stays small and weak. The energy readings are mostly in the 30-80 range, which is weak. The patterns are consistent – small, choppy, and messy. Not worth paddling out for.
There’s a slight uptick in swell size around the 26th and 27th of July, with waves hitting 4ft to 6ft from the NW and energy jumping into the 200-300 range (moderate energy). But the wind is still cross-on and the conditions are described as poor. The period is short (7-8 seconds), so it’s going to be a messy, weak-shouldered, choppy mess. For these sizes, the cross-on wind will just ruin any chance of a clean face. It’s more interesting for kite surfing than paddle surfing at that point.
Truth is, the forecast is a blank run for decent surf. Expect a gap of over a week with no real recommendations. Keep your eyes on the charts, but for now, don’t get your hopes up.

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