Time of day climate
We speak of a daytime climate when the mean temperature differences between day and night are greater than the temperature differences between the individual months. The temperature fluctuations within a day are thus higher than the mean temperature amplitude within a year. Time-of-day climates are found mainly in the tropics and most pronounced in the always humid tropics .

A time-of-day climate is usually found in an almost complete absence of climatic seasons. This situation results from daytime solar radiation that is little variable over the course of the year, as can be found in the angle of solar radiation around the equator, which does not change much over the year . The time of day climate is accordingly characteristic of the tropics . The sun rises at around 6 a.m. and sets at around 6 p.m. all year round. The twilight is only of short duration. Since there is no spring, summer, autumn or winter, the seasons in these areas are divided into rainy seasons and dry seasons . These differences dominate life in the savannah and in the tropical monsoon forest . In the tropical rainforest , on the other hand, the distribution of precipitation and temperature are equally balanced; it usually rains at the same time of day. As a rule, precipitation is only significantly less or entirely for a few days or weeks. However, the altitude also influences the climate in the tropics. While the mean daily temperature at sea level is around 25 ° C, at higher altitudes, such as in the high mountains of Africa (e.g. Kilimanjaro ) and in the equatorial part of the Andes , freezing temperatures can be found.
A seasonal climate with clearly defined seasons can be found in all climatic zones except the tropics .
