The Lowdown
Alright folks, Rusty here. We’ve got a 16-day window for Beliche (Portugal) and this one is a bit of a slow burn. The good stuff is not right now. There’s a long patience game to play, with a couple of very specific windows that will make it worthwhile for the dedicated surfer.
The water temperature is sitting at 66°F, which is 6°F colder than normal. That’s a very unusual chill for this time of year, so you’ll be reaching for the thickest wetsuit in your quiver right off the bat.
We start off with a couple of days of very ordinary, weak conditions. The 12th and 13th offer clean surf but it’s small, with weak energy (118 to 150 on the energy scale) and short period windswell.
The first real pulse arrives on Monday the 14th with a 3ft to 4ft NW swell and a period of 12 seconds. The energy is building to a moderate 383, but the morning is ruined by cross-shore winds. The afternoon cleans up with a cross-off breeze, making it rideable but nothing to call home about.
Tuesday the 15th morning is surprising. It’s small – just 2ft – but it’s clean with a moderate offshore wind. The energy is weak (101), but it’s a fun little session for a log or a fish if you’re desperate for a paddle.
The big change comes mid-week. A strong NNW wind kicks in on Wednesday the 16th, blowing 28 mph. The swell jumps to 8ft to 10ft, and the energy rockets up to a very strong 919 to 1321. This is powerful, lumpy, and messy. The offshore wind makes it look clean, but the period is short (8-9 seconds) and the conditions are marked as poor. This is strictly for the experts, and even then, the paddle-out is going to be a battle. Honestly, with that wind and energy, this setup looks more interesting for kite surfing than paddle surfing.
Patience pays off in the second week. Friday the 18th sees the wind ease to a moderate offshore, and the swell settles at a solid 7ft to 7ft from the NNW. The energy is strong (856), and the conditions are marked as good. This is a proper session for experienced surfers.
The standout, and I mean the absolute standout of the entire forecast, is Saturday the 19th. The morning brings a 5ft NW groundswell with a very long period of 15 seconds. The energy is sitting at a very strong 1168. The wind is a light cross-off breeze. The conditions are marked as very good. This is the day. Point breaks and reefs will be your friend for those long-period lines; beach breaks might be a bit too straight. It’s for all levels except absolute beginners, and it will be worth the wait. The afternoon stays solid with a 4ft wave and a long 14-second period, still clean.
After that high, a brutal easterly wind system moves in. Sunday the 20th through Tuesday the 22nd morning is blown out by strong cross-shore winds and messy conditions. The energy stays moderate to strong, but the quality is shot.
A final flash of hope comes on Tuesday the 22nd afternoon with a glassy, clean 5ft NW swell with a 13-second period. The energy is moderate (712). This is a solid session for a sunset surf if you can get out before the wind swings.
From Wednesday the 23rd onwards, we fade out. The swell drops, the winds stay messy, and by the 26th and 27th, we’re looking at tiny, weak waves with less than 3ft of energy. The run fizzles out completely by the end of the 27th.
So, to boil it down: Saturday the 19th is your absolute target. That long-period NW groundswell with clean conditions is the best on offer. Friday the 18th is a solid runner-up for a more powerful, wind-affected session. The rest is either waiting, washing, or not worth the drive.
Rusty.

Information about the Beliche Surf forecast
The above surf forecast table for Beliche provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Beliche can be found by selecting the local surf guide option on the grey menu. Our Beliche 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 (Beliche) 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 Beliche 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.
Beliche is 29 km (18 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
