How does the season affect how much water I need to drink?

Getting adequate fluids (staying hydrated) is always important, and the seasons might affect that goal. Exposure to warmer temperatures can increase the amount of water you lose through sweating and require that you drink more. Other factors to consider besides the time of year are your level of physical exertion, medicines you take, your diet (alcohol increases fluid loss, for example) and how healthy your kidneys are. If your urine looks dark yellow instead of clear to light yellow, you may need more water intake. 
Getting enough fluid intake during the winter season is just as important as when temperatures are high. When you're exposed to extreme temperatures -- whether it's very hot or very cold -- your body uses more water to maintain its normal temperature. Also, in the winter you're exposed to heated air which evaporates water from your skin. Be sure to drink water or other fluids whenever you're thirsty. And, make sure children and elderly adults drink enough fluids, too. Adult women need about 9 cups of fluids a day; adult men about 13 cups.
