Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in ZA as well as at Singapore, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

The year in Singapore

Rainfall can be frequent, especially during the monsoon season. Make sure to check the weather in advance, as heavy rain can impact outdoor activities.

Busiest	early Nov to late Dec — This period aligns with the holiday season, attracting more tourists and increasing prices.
Quieter, still good	early Jan to late Feb — These months see a balance of comfortable weather and a reduction in tourist numbers post-holiday. early Mar to late Jun — Generally less crowded and better value before the peak of the year-end holidays.
Wet or stormy	mid Nov to late Jan — monsoon, moderate
Watch out for	haze; heavy rainfall

This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
