Annual and daily cycles of weather and daylight, including seasons, wet and dry seasons, growing seasons, polar night, midnight sun and the effect of Sun angle on climate. A topic belongs here when its cited article describes a seasonal or daylight cycle. It excludes extreme events and past climate periods. These cycles follow from the tilt of the Earth and set the rhythm of farming, ecosystems and human activity.

The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the solar zenith angle (the angle of incidence at which sunlight strikes Earth) varies by location, time of day, and season due to Earth's orbit around the Sun and Earth's rotation around its tilted axis.
