However, AFP reporters saw heavy rain and flooding in at least one eastern neighbourhood, with residents wading through thigh-high waters.
Schools have been closed and people urged to work from home – a call that many heeded, with streets and public transport networks noticeably quieter on Monday morning.
“Some areas in Bangkok are still facing high water levels,” government spokesman Ekkapob Pianpises told a news briefing.
Drainage systems had reduced water levels to the point that more people could travel, he added.
Thailand is used to wet weather and September is the peak of the rainy season, but many residents said this year seemed worse than previous ones.
