Kuala Lumpur has a tropical rainforest climate with consistent temperatures year-round (24-33°C/75-91°F). High humidity and frequent afternoon thunderstorms are common. Two monsoon seasons bring heavier rain but rarely disrupt daily life significantly.
Air quality can be challenging during certain periods, especially during regional haze from Indonesian fires. City center areas experience more pollution, while areas near parks (KLCC, Bukit Bintang) tend to have better air circulation.
