The barometric pressure in Ancaster, Ontario, Canada is influenced by its location in the Great Lakes region. Low-pressure systems from the lake can bring stormy weather. High-pressure systems from the northwest can bring clear skies.

Ancaster is situated on the Niagara Escarpment, a unique landform that stretches from Queenston to Tobermory. This escarpment creates a corridor for air masses to move through. As air rises or falls over the escarpment, it cools or warms, affecting the barometric pressure.

The surrounding landscape of rolling hills and forests also plays a role in shaping the local weather. Moist air from Lake Ontario can become trapped in the hills, leading to fog or clouds. Meanwhile, the forests help to moderate temperatures and block winds.
