What if your summing pool loses water when it cold out side why is that?

A summing pool may lose water in cold weather due to evaporation and condensation processes. When temperatures drop, water can evaporate more slowly, but if the air is dry, it may still lose moisture. Additionally, if the surface temperature of the water is warmer than the air, condensation can form on the surface, leading to water loss. It's also possible that ice formation or leaks exacerbates the problem.
