The biome with the hottest temperatures is the desert biome. Deserts are characterized by their extremely low precipitation levels and can experience dramatic temperature fluctuations.
During the day, temperatures in many deserts can soar above 100°F (38°C), particularly in places like the Sahara Desert and the Sonoran Desert. It’s not uncommon for these regions to have recorded temperatures exceeding 120°F (49°C) in some areas.
One reason deserts can achieve such high temperatures is due to their geographic location, typically situated near the equator, where sunlight is most intense. Additionally, the lack of moisture in the air means that there is very little to moderate the temperature, causing rapid heating during the day.
In contrast, at night, desert temperatures can drop significantly, sometimes to near freezing, due to the lack of cloud cover that would otherwise retain heat. This fluctuation highlights the extreme conditions typical of desert biomes.
