Violent crime
Singapore consistently ranks among the safest cities in the world — walking alone at night is genuinely low-risk in almost every neighbourhood.
Common scams
Petty scams targeting tourists are rare compared to many major cities, though standard travel caution around unofficial "tour guides" and unlicensed money changers still applies.
Practical basics
The main real risks are heat exhaustion and dehydration rather than crime — carry water and pace outdoor activity around the hottest part of the day.
