Total to central Bangkok typically ฿300–450. Grab is reliable and avoids negotiation. Limousine services (฿800–1,500) are available from the arrival hall. Buses are cheap but slow given Bangkok's traffic.

Bangkok Climate

Tropical monsoon climate. Hot season (March–May) reaches 38–40°C with high humidity. Wet season (May–October) brings daily heavy rains and occasional flooding. Thunderstorms cause flight delays regularly. Suvarnabhumi sits in a flood-prone area east of Bangkok. The 2011 floods came close to the airport perimeter.

Cool season (November–February) is the most comfortable for travel (25–32°C) with lower humidity and good flying weather. Haze from agricultural burning occasionally reduces visibility in March–April.
