The climate of Singapore in september is tolerable

September is one of the driest months of the year. However in reality, it is simply a gradual withdrawal of the rains - since they continue to manifest from time to time during the day. As a result, the weather in Singapore throughout September is just suitable for outdoor outings.

Singapore at the Beginning of September

The beginning of September is still characterized by relatively abundant rains, as wet mornings are followed by wet afternoons and such is quite common. To this must be added the high temperatures which result in a warm atmosphere; from dawn until dark.

Singapore in the Middle of September

Towards the middle of the month, the September climate in Singapore takes advantage of the notorious withdrawal of rains. In fact, even if the beginnings of the days are still rainy - the rest of the time is often pleasant with beautiful sun and a warm atmosphere.

Singapore at the End of September

Towards the end of the month, the climatic conditions are identical to those of the previous period. This means that the rains at the beginning of the day dissipate quickly enough to give way to the beautiful sunny afternoons. On the other hand, the heat continues to persist and sometimes translates into a humid and warm atmosphere.
