When to Fly from San Francisco (SFO) to Singapore (SIN)

Singapore experiences warm weather year-round, with temperatures around 30°C (86°F). However, the period from February to April is slightly warmer and less rainy, making it an ideal time for tourists, which can sometimes result in slightly higher travel costs due to demand.

 

Although May to July is considered peak tourist season, June is the most expensive month for this route, with fares often climbing 30 to 40% above average. This is due to various festivals and the Great Singapore Sale, a city-wide retail event that attracts many visitors. While the weather is favorable, flight and hotel prices can be at their highest due to increased demand.
