When the surrounding temperature drops, blood vessels under our skin are tend to constrict in order to decrease the loss of heat. Since heat does not lose through sweating, more water retained in the bloodstream and heat is conserved in our body. Osmolarity of the blood decreases due to the increase of water level. ADH secretion decreases, less water is being reabsorbed from the tubule into the bloodstream, thus urine output will be higher.
Besides, total metabolism of our body increases as well in order to generate more heat. Thus the frequency of urinating increases too.

It takes a lot of energy for the body to keep liquids warm. Your body tries to get rid of extra water so it can focus on keeping the rest of you warm instead.
You'll also stay warmer if you don't resist the urge. If you've ever been camping on a cold night and wake up needing to urinate, you're far better off getting out of the sleeping bag for a minute and going out in the cold to pee. You'll stay warmer in the long run.

When we are in a cold environment, blood flow to our internal organs is increased to keep our organs warm.The increase in blood flow to the kidneys causes more blood to be filtered thus producing more urine.

the temperature dropping, and we get colder, so the body regulates its temperature, and we have to go pee.
