How does the water cycle change during the year?

In theory, the water cycle remains constant throughout the year.

The three basic processes of the water cycle are evaporation, condensation, and precipitation. The details can get more intricate as you go along (evapotranspiration, for instance, is the process of drawing water from plants using heat energy instead of directly from a water source), but the fundamentals always stay the same.

Whether a body of water is large or small, when light energy from the sun reaches it, the atoms within each water molecule begin to gain energy and move faster, breaking and creating old and new bonds more and more quickly. The water evaporates due to the molecules' increased versatility, turning the water into a gas that is more freely moving and has a tendency to rise.

As it ascends higher into the sky, the water vapor cools and eventually condenses, or goes back to being primarily liquid, to form clouds.

When the water in these clouds runs out, they release the moisture as precipitation, which can take the form of rain, sleet, hail, or other precipitation.

This process remains constant, but the kind of precipitation varies, which I think is what you might be referring to. Precipitation can take on any of the aforementioned forms or even several others depending on the temperature at the time it occurs. The temperature's influence on the type of precipitation, however, is largely determined by the Earth's position in relation to the sun rather than the water cycle itself.

The water cycle is influenced by seasonal variations in temperature and precipitation, leading to fluctuations in evaporation, condensation, and precipitation levels throughout the year.
