If we talk about weather conditions, then the most "dry" months is the time from June to September. On the contrary, the most "wet" months in the year are from November to January, when the rains are most likely. But the prices for hotels in the summer are traditionally higher than the winter season, with the exception of the festive and festival periods that happen in Singapore all year round, because the weather in this tropical country is always hot and humid in any case.
