Taxis from arrivals cost S$20–35 to Orchard or Marina Bay, including airport surcharge (S$5) and possible peak surcharges. Grab is cheaper and very reliable in Singapore. Coach buses serve Johor Bahru (Malaysia) from the airport.

Singapore Climate

Equatorial climate with no true seasons, hot (26–33°C) and humid year-round. Changi is one of the most reliable airports in Asia for flight operations: thunderstorm cells are intense but brief, typically clearing within 1–2 hours. Most delays are weather-related and short.

Northeast monsoon (November–January) brings the most consistent rain, sometimes for days at a time. Haze from Indonesian forest fires (typically August–October) occasionally reduces visibility and triggers air quality warnings, but rarely grounds flights. Changi's operational efficiency means it handles weather disruptions better than most airports its size.
