Flip-flops for Singapore in December
Verdict
Optional
Warm enough to wear in the evening or on the beach; not on a city walking day.
Why
Singapore in December averages highs of 86°F, lows of 75°F, 19 rainy days.
That climate makes flip-flops a judgment call. Warm enough to wear in the evening or on the beach; not on a city walking day.
