The Lowdown

Alright folks, Rusty here. I've got the scoop on what's coming up for the next couple of weeks, and I'll be straight with you – it's a bit of a flat spell.

Right now, and for the entire 16-day window, we're looking at a complete blank. There is simply no swell on offer at Niagara Rivermouth. The water temp is sitting at a pretty normal 70°F for this time of year. From the 28th of August all the way through to the 12th of September, the combined energy of any swell directed here is a flat zero (0). That's a solid 16 days of nothing.

The wind is all over the place, switching from offshore to onshore, to glassy, and back again, but it doesn't matter because there's nothing for it to blow on. We get a few moments of glassy conditions on the afternoon of the 3rd of September, and again on the 5th, but without any waves, it's just a flat, clean lake. Even the offshore winds on the 29th and 30th of August can't do a thing for us.

Look, this is one of those rare stretches where the river mouth just goes to sleep. There's no point in even checking the cam. It's a poor outlook, plain and simple. Sometimes you get a blank run like this. The good news is, it never stays this way forever. Keep an eye on the charts, and I'll be back when the juice starts flowing again.

Rusty.

Information about the Niagara Rivermouth Surf forecast

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