# WIND - Sheltered position when wind blows from SE through S to SW.   1 Rain season: Jan 1st to Dec 31st.   2 Snow season July 1st to June 30th.   3 Snow manually measured usually around 7AM and 7PM.   5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present).   6 Sun Spots - Data from WDC-SILSO, Royal Observatory of Belgium, Brussels.   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average only to day 15 of just the month of September for this station since 2008.   11 Historical average rain this season to day 15 of September for this station since 2008.

 Weather Definitions, Weather and Earth Facts  
Fact 10 - HUMIDEX
Definition Humidex - Over the years, several measures have been proposed to relate various combinations of temperature and humidity into a single number to approximate what hot, humid weather feels like to the average person. Of these, humidex is the one most familiar to Canadians. Humidex was introduced into Canada in 1965. The index is a summer analogue of the wind chill factor in that it is an equivalent air temperature. Air of a given temperature and humidity is equated in comfort to air of a higher temperature that has a negligible moisture content. Comfort is quite subjective and largely dependent on the age and health of the individual. Weather conditions causing prickly heat in an infant may result in heat cramps in a teenager, heat exhaustion in a middle-aged and heat stroke in a senior. Humidex is also limited as an overall hot-weather comfort index because it does not consider other factors such as pressure, wind speed, precipitation, sunshine or pollen.
