Gloomy skies over office tower blocks in Bangkok, Thailand

Overcast grey skies and office tower blocks during the gloomy annual Thai rainy season in Bangkok, Thailand on October 1, 2021. Thailand and other countries in Southeast Asia such as Malaysia, Indonesia and the Philippines experience their annual monsoon rainy season from July to late November. Soaring temperatures reaching 35 degrees Celsius are often followed by powerful tropical storms with thunder, lightning, rain and flash floods which cause rivers to flow faster and become dangerous. Many of the under-developed nations struggle to cope with the heavy rain due to under-investment infrastructure.
