Winter is the coolest temperate season, typically occurring after Autumn and before Spring. During the Winter, either the Northern Hemisphere or Southern Hemisphere is exposed to less direct sunlight. The strength of the sun is at it's lowest at the Winter solstice towards the end of December in the Northern Hemisphere and June in the Southern Hemisphere, although these months usually mark the beginning of the season due to seasonal lag. The winter then last until February/August even though at that point the sun starts to gain strength, but is again cooler due to seasonal lag.
