Flip-flops for Singapore in May
Verdict
Optional
Warm enough to wear in the evening or on the beach; not on a city walking day.
Why
Singapore in May averages highs of 91°F, lows of 78°F, 16 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.
