Today's Weather Trivia

5 July

1921: The Niagara region baked under torrid heat registering 35.6°C in the shade. One woman resting on a ledge near the water's edge was overcome with heat and tumbled into the Niagara River a short distance from the falls. Another woman fainted from the excitement and followed her in. People near the Goat Island Bridge saw the women slip into the whirling river and sounded the alarm. Both were rescued.
