What to watch in Lake Ontario
Lake Ontario is deep and steep-sided, so it stratifies strongly in summer and holds cold water below the thermocline while wind-driven upwelling swings surface temperature along the shore. Seas build quickly on a sustained westerly or northeasterly blow — read wind and water temperature together before you go.
