Singapore from London
10,860 km, about 14h 10m in the air. Every month scored for the weather at Singapore and for the holidays that crowd it out at both ends.
Affiliate links: we may earn a commission if you book through one, at no extra cost to you. It changes nothing above — the scores are computed from climate and fare data before any link is built.
Free, on Telegram. One tap — LON is already chosen. We write
when a fare is genuinely below what that route normally costs, and
/stop ends it.
Public holidays at London move this destination's year too little to make it a different answer, so the Singapore page is the one of record. This one is kept for the distance and the flight it implies.
No fare history on LON–SIN yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in GB 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.
