The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the St. Lawrence region over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week and a half is a real struggle. There’s a whole lot of nothing happening. We’re looking at a solid gap from now until the morning of the 23rd of July where there’s just no surf worth paddling out for. The energy is barely registering, with the combined swell energy staying below 100 (weak) and most days offering up tiny, weak waves. If you’re desperate, you might catch a knee-high ripple on the 18th or 19th with some clean offshore breezes, but honestly, it’s not going to get you wet for long.
The 23rd of July morning finally shows a pulse of life. We’ve got a 3 ft swell coming from the WSW, but the conditions are still ordinary. The energy is moderate at 51, but it’s not a stand-out.
Now, hold on to your board shorts, because things finally get interesting on the 24th of July. The Friday morning session is a solid contender. A 4 ft swell from the WSW with a period of 8 seconds is pushing moderate energy right at the beach (344). The big win here is the clean conditions – we’ve got a moderate offshore wind from the ENE. This is a real chance to get some halfway decent lines at Les Conches.
But the true standout, the one you’ve been waiting for, is the morning of the 25th of July. Saturday morning is looking absolute magic. The swell jumps to 6 ft from the WSW, but the period is a respectable 10 seconds, giving it some real punch. The combined energy is a solid 634 (moderate). The wind drops to a glassy 5 mph from the east. It’s going to be clean, smooth, and the waves are going to be proper. This is more than a beginner wave – at 6 ft, it’s getting into the intermediate-to-expert fun zone. This is the best on offer.
After that, the 26th and 27th of July still have some size (4 ft to 5 ft) but the wind swings around to the west and WNW, making it cross-on and choppy for the afternoons. The mornings are still the call.
The water temperature is a real standout for this time of year, coming in at 72°, which is 5° warmer than normal. That’s a very unusual anomaly for late July, so you’ll be in for a warm, pleasant paddle.
So, to sum it up: the first week is a write-off. The 24th morning is a sneak peek of what’s coming, but lock in the 25th morning for the best session. Get out there and enjoy it.
Rusty.

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