The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for our local stretch. Gotta be straight with you, the next couple of weeks are looking like a bit of a mixed bag with some long flat spells. Hang in there.
Overall, we're looking at a tough period. A run of days with no surf worth mentioning, then a few promising windows with clean conditions, especially around the 20th. The water temp at 67° is about what you'd expect for this time of year, so nothin' to complain about there.
Starting on Thursday, the 13th, we've got nothing going on. Wave heights are tiny at 3 ft from the WSW, but with a cross-onshore wind, it's just a mess. That stretches through until Sunday the 16th, where we finally get a sniff of something. Sunday morning brings a clean, gentle offshore wind from the NNE. The swell is tiny though, only 2 ft from the west, so the combined energy is really weak (41). It's surfable but only just, a real knee-slapper for a longboard.
Then it's back into the doldrums. Monday the 17th through to Wednesday the 19th is just poor surf and ordinary conditions. Small, weak swells and onshore or cross-onshore winds are the story. You're better off doing something else.
Now, here's where things get interesting. Thursday the 20th is the standout of this entire outlook. The morning kicks off with a 5 ft swell from the west, with a solid 11-second period. The wind is a clean offshore from the NNE, so it'll be clean and lined up. The combined energy is moderate (459) so there's some push behind it. But it's the afternoon that's the real treat. The swell builds to 6 ft from the WNW, with a 10-second period and glassy light cross-shore winds. The combined energy jumps right up (1113). For Guidel Plages, this is the best we're gonna see. The swell direction (WNW) is a touch off the optimum SW, but with conditions that clean, it'll be worth a paddle. It's a very consistent spot and crowds can be a problem sometimes, but a Thursday afternoon might thin the herd a bit. This is for experienced surfers though; at 6 ft it's pushing past the beginner zone.
Friday the 21st gives us a quick morning session with a 3 ft W swell and clean offshore winds. The energy is moderate (113). It's alright, but ordinary. The afternoon gets choppy again.
From Saturday the 22nd right through to Tuesday the 26th, it's a long, grim run. Mostly onshore or cross-onshore winds, weak little swells, and poor conditions. There is a pulse of 5 ft on Tuesday the 25th but with a short 6-second period and strong onshore wind (19 mph), it's just a washing machine. Not for surfing.
We finally see some size (7 ft) on Thursday the 27th and Friday the 28th, but the wind is howling onshore or cross-onshore at 16-19 mph. With the combined energy at 418 and 450, there's power there, but the wind will destroy any shape. For a beach and reef setup like this, that's more of a kite-surfing or wind-chopper afternoon than a paddle-surfing session. Conditions are just plain poor.
So, to wrap it up, hold out for Thursday the 20th. That's your day. The rest is either waiting, or dealing with less-than-ideal conditions. The ocean will turn it around eventually – it always does.
Rusty.

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

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 Guidel Plages 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.
