The Lowdown
Alright, Rusty here. Let’s call it like it is – we’ve got a long, dry spell ahead for Dunkirk. Nothing’s happening. For the first week, the swell charts are empty.
Starting Wednesday the 5th of August, there’s zero surf. Water temp is sitting at 75°F, which is about 3°F warmer than average for this time of year, so it’s a touch warmer than normal – nice for a dip, but no waves. Wednesday morning has light cross-offshore wind from the SW at 6 mph, but with no energy, it’s pointless. Wednesday afternoon goes glassy with a westerly 3 mph breeze, still dead flat.
Thursday the 6th stays flat. Friday the 7th, same story. Saturday the 8th of August finally coughs up a tiny 0.3ft NW windswell in the afternoon, period only 5 seconds – a pathetic 2 units of combined energy. That is barely a ripple. Sunday the 9th has a 1ft pulse from the west with a 4-second period, still only 3 units of energy. Weak. This tiny, short-period slop carries on through to Tuesday the 12th.
Then from Wednesday the 13th of August all the way through to Thursday the 20th, it goes completely flat again – no swell heights recorded at all. So you’re looking at a solid 16-day stretch of nothing worth paddling out for. Dunkirk is usually a consistent, exposed spot, but the ocean just isn’t delivering. The wind does swing offshore from the SE a couple of times (like on the 5th morning and again on the 18th), but with zero swell, that's just a clean lake.
No standout here, no best on offer. This is a blank run. Keep the board in the rack and check back later – forecasts can shift, but right now it’s a bust.
Rusty.

Information about the Dunkirk Surf forecast
The above surf forecast table for Dunkirk provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dunkirk can be found by selecting the local surf guide option on the grey menu. Our Dunkirk 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 (Dunkirk) 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 Dunkirk 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.
Dunkirk is 36 km (22 miles) from Port Colborne. If you plan a vacation in Lake Erie - United States, look for hotels and other accommodation in Port Colborne. Port Colborne has rooms for a wide range of budgets as well as car hire and transport links.
