The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [2] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion.

This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
Canada's annual average temperature over land has warmed by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. [4] The rate of warming has been higher across the North and in the Prairies. [ 4 ]
The denser urbanscape makes for warmer nights year-round; the average nighttime temperature is about 3.0 °C (5.4 °F) warmer in the city than in rural areas in all months. [132] However, it can be noticeably cooler on many spring and early summer afternoons under the influence of a lake breeze, since Lake Ontario is cool relative to the air ...
The July daily average temperature is 75.4 °F (24.1 °C), with afternoon temperatures peaking at 84.5 °F (29.2 °C). In a normal summer, temperatures reach at least 90 °F (32 °C) on 17 days, with lakefront locations staying cooler when winds blow off the lake. Winters are relatively cold and snowy.
