LAKE DAY
🌙 TOMORROW'S LAKE FORECAST
Should you hit the beach or the boat today? Live wind, waves & water for Ontario's Great Lakes.

Sandbanks Provincial Park in Prince Edward County holds the world's largest baymouth dune system and two very different Lake Ontario beaches — warm, shallow Outlet Beach and the wilder Dunes side.
LAKEDAY combines live open-water data for Sandbanks into two simple answers: is it a beach day, and is it a boat day? The verdicts above update from the Open-Meteo forecast model and NOAA/Environment Canada buoy 45135 every time you load the page, and the hour-by-hour strip shows when today's boating window opens and closes.
The live verdict at the top of this page answers that right now — it combines today's air temperature, cloud cover, rain chance and wind for Sandbanks, refreshed on every visit. Green means go, yellow means pick your window, pink means skip it.
The WATER number above is the latest reading from Lake Ontario buoy 45135, the nearest open-water monitoring buoy. Nearshore water at Sandbanks is often a degree or two warmer than the open lake on calm sunny days, and colder for a day or two after strong offshore winds.
Check the BOAT DAY verdict and the 24-hour window strip above — green hours mean gusts under 12 knots and waves under 0.4 m, our small-craft comfort threshold. Great Lakes chop builds fast; always confirm against the official Environment Canada marine forecast before launching.
