The Lowdown
Alright folks, Rusty here. Let’s get into it. The next 16 days are a bit of a mixed bag, with plenty of onshore chop to work through, but there is one real window that should get your attention if you’re patient.
We kick off Sunday the 26th of July with no real surfing on the table at Cogumelo. The swell is there at about 4ft from the NW but with a short, weak 7-second period and a cross wind messing things up. The energy is low (170). The water temp is about average for the time of year.
Monday the 27th of July is our first real chance. Morning sees the wind go glassy, with light airs and a clean surface. The swell drops to 3ft from the NW, period still short at 7 seconds, and the combined energy is weak (80). It’s small, but with those glassy conditions the waves will be clean and rideable for an intermediate. This is your best call in the early part of the outlook. The afternoon turns onshore and choppy again, so get on it early.
From Tuesday the 28th of July right through to Friday the 31st of July, it’s a mess. Wind is either cross or cross-onshore, swell is tiny (often under 3ft) or completely flat on Friday the 31st morning. The energy is mostly weak, with a brief spike to 162 and 184 on Tuesday and Wednesday afternoons, but the winds ruin it. You’re looking at choppy, poor surf conditions. Not worth paddling out.
The first week of August doesn't look much better. Saturday the 1st and Sunday the 2nd see small NW swells under 2ft with consistent cross-onshore winds. Monday the 3rd is more of the same.
The standout period arrives around Tuesday the 5th and Wednesday the 6th of August. On Tuesday the 5th, there’s building swell from the NW. The morning sees clean-ish cross-shore wind and a pulse at 7ft with a 9-second period. The combined energy jumps to 667 (moderate to strong). This is a solid West swell, but at 7ft it’s getting into the expert-only zone, especially with a short period that will make it dumpy and harder to paddle into. Still, that’s the biggest, most energetic window in the whole outlook. It’s marginal due to some tide questions, but for experienced surfers, that Wednesday morning is the one true standout. The afternoon of the 5th drops off quickly.
Thursday the 6th and Friday the 7th hold some size (5ft to 6ft) but the cross-onshore wind builds to 12–16 mph, making for moderate to choppy conditions. The energy remains moderate (407–519) but the quality is poor.
Saturday the 8th and Sunday the 9th of August still have some size (5ft–6ft) but the wind stays cross-onshore or cross, so it’s a frustrating pattern. The energy through Sunday afternoon hits 515, but with onshore wind, it’s not going to be clean.
Monday the 10th of August wraps it up with a drop back to 3ft from the WNW, cross-shore wind, and weak energy (179).
Bottom line: The only real window where conditions align is Monday the 27th of July morning – small but glassy, perfect for a longboard or a groveler. For bigger swell and more power, Tuesday the 5th of August morning has the size and energy for experts, but don’t expect perfection. Keep an eye on that wind shift.
Rusty.

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.

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.
