Thailand is going through one of its most widespread flood periods of the year. Authorities have recorded flooding in nineteen provinces and Bangkok, with more than a million people affected and a death toll that has risen over the days.
What happened
Monsoon rains, particularly heavy this year, have overflowed several catchment areas in the centre and north. Water first hit farming provinces, then moved down towards the Chao Phraya delta and the capital, part of which is built on subsiding low-lying ground.
The result is a slow flood spread over weeks, which drowns whole districts and saturates drainage.
The toll as published
According to figures relayed by Thai and international media, flooding has affected nineteen provinces and Bangkok, hitting about 1.22 million people. The human toll reported by several outlets stands at 82 deaths. These figures change as evacuations and assessments proceed.
The situation in Bangkok
The capital was partly hit, with flooding concentrated in eastern districts, notably Nong Chok and Lat Krabang. The city declared some areas public disaster zones, then reduced the perimeter as water receded. As of 22 October only two districts remained classified, indicating a gradual decline elsewhere.
The authorities’ response
Bangkok mobilised technical teams to assess housing damage, with several hundred technicians deployed. It also sent telephone warnings to residents, specifying that official messages contain no link — a warning against scams that flourish during disasters.
Why the water rises so much
Three factors combine: above-average rainfall, a difficult topography (Bangkok sits a few metres above sea level and some districts are subsiding), and urbanisation, which seals surfaces and blocks the canals once used for drainage.
What it changes for a traveller
In the central tourist areas life continues: hotels, restaurants, transport work and major sites remain open. But check before going, and accept longer journeys. Excursions outside Bangkok may be cancelled or rerouted.
Transports
International flights are not affected. Rail links to the north may be interrupted or diverted, and some road sections are cut. In Bangkok, metro and skytrain usually run normally and are the most reliable means during a flood.
Practical advice
Follow local information, avoid flagged areas, and never cross a flooded road on foot or by scooter: depth is deceptive and manhole covers can lift. Bring closed shoes and a change of clothes. If your hotel is in an affected area, contact it before travelling.
The fake-message scam
Authorities explicitly warned that official flood messages contain no link. Any request to click for aid, compensation or a refund should be treated as suspect.
Should you cancel?
It depends on the itinerary. A Bangkok stay with classic sites, or the west-coast beaches, runs normally in most cases. An itinerary in the affected central-north, or a river cruise, needs daily verification.
What happens next
Water is receding in several provinces, and cleaning and assessment have begun. But water takes weeks to leave low areas, and material damage remains visible for long. The rainy season ends gradually in November.
Wider context
Thailand has recurrent major floods. What changes is accumulation: saturated soils, full reservoirs and a vulnerable capital. For residents these episodes are not an anomaly but a constraint, which explains the speed of relief arrangements.

FAQ
Is Bangkok entirely flooded?
No. Flooding is concentrated in some eastern districts, notably Nong Chok and Lat Krabang. The tourist centre is largely spared.
Can you get around Bangkok?
Yes, in most districts. Avoid flagged streets and prefer metro and skytrain.
Are airports affected?

Recommended at any time, and essential if travelling in affected areas.
Where to follow news?
Thai press websites and official city accounts, cautiously on social media.
