The climate in the Australian rainforest is hot and humid with frequent rain. Although there is no dry season as it is almost always rainy, the wet season is from December to March during which the area gets 60% of the year's rain ("About the Daintree Rainforest." n.d.) Since it is close to the equator, it has a lower altitude which causes higher temperatures. Temperatures range from 15-36 degrees Celsius (Buckman n.d.). The average humidity in the summer is around 80-90% (Buckman n.d.).
Why does the Daintree Rainforest stay so humid and moisture-rich? The water cycle does not create or lose water; it always goes somewhere and so in the case of the Daintree Rainforest water would runoff into the Pacific Ocean, the Daintree River and other large bodies of water and eventually evaporate back into the atmosphere. Rainforests help keep the water cycle going by adding moisture to the atmosphere through transpiration. That is why it is a big problem when areas of the Daintree are being clear cut because it lowers the amount of moisture that enters the atmosphere, which can affect the rainfall and even cause a drought in certain areas. Since the Daintree gets a lot of the sun's energy and is such a hot area, the plants transpire more often so that they will not wilt. This causes it to rain so often in rainforests and keep them moist. The Daintree River often floods during the wet season ("About the Daintree Rainforest" n.d.).
