You can travel to Singapore anytime. The island witnesses a hot and misty weather throughout the year. And with a fast stream of trade tourists, the city's accommodations are seldom at a loss of occupants and maintain affordable rooms to stay. To stay away from the excessive rates, steer clear of well-liked proceedings or national vacations such as Chinese New Year. But note that, rain is likely to pour round the year.
If you want to travel Singapore then this is the season to travel. Mixing winter travelers, the normal traffic and various vacation carnivals (Chinese New Year) and you will notice Singapore overflowing with travelers. Thus, if you travel between November and January, you will come across with the Monsoon season of Northeast, which pours lots of rain on the town. In November and December we see the highest rainfalls.
Travel in the end of summer and previous fall to take pleasure in a small split in the traveler’s traffic. You will also get the chance to enjoy the Great Singapore Sale, the best time to choose some designer clothes. The South-West Monsoon comes between June and September, but it is less harsh than its North-East complement.
