The climate in Singapore can be described as a tropical rainforest one. It does not have any clear season as such and the temperature normally stays the same throughout the year. Other common features are high levels of humidity and lots of rainfall throughout the year.
The temperatures in Singapore normally fluctuate within 23 to 32 degrees Celsius. On an average the relative humidity of the Asian nation hovers close to 79 percent during the morning.
In the afternoons the average humidity levels come down to 73 percent. This can reach 100 percent during months when the country experiences high rainfall. The western part of the country receives more rainfall than its eastern counterpart due to the rain shadow effect.
This makes the eastern part drier and warmer than the western part of Singapore. At times this has also caused disparity in weather patterns across the various parts of the island nation. It has often been seen that Bukit Timah, a smallish hill in Singapore plays a major role in determining its weather trends.
Often a certain part of Singapore receives rainfall but the other part gets sunshine – this is a rarity given the small size of the country. The hottest months in Singapore are May and April, while the months between November and January experience the maximum amount of rainfall.
Singapore never has a uniform year round weather because it has two separate periods of rainfall. The Northeastern Monsoon is the earlier one to occur – it takes place within December and March.
The Southwestern Monsoon happens from June to September. The months without rain are normally characterized by weaker winds and lesser rainfall. The Northeastern winds are common during the first period of rainfall and the southeastern/southwestern monsoons are seen at time of the Southwestern monsoon.
During December and January cloudy conditions are prevalent with regular showers during the afternoon and wind speeds reach maximum speeds of 20 kilometers per hour. There are 1-3 days spell of moderate or heavy rainfall that occurs on a widespread basis during this time. However, during southwestern monsoon season rainfall happens during early afternoon or late morning.
Haze is a common feature during July to October – this happens primarily because of the bush fires that take place in Indonesia, which lies next to Singapore. Much of this small Asian nation’s climatic patterns result from its location with respect to the Equator. The maritime exposure is a major contributor in this regard. On an average, Singapore experiences almost 2,340 millimeters of rain per year.
