Data from meteorological agencies shows that the global warming trend will continue, although the La Nina phenomenon may somewhat ease in some areas.
Thailand: Temperature may reach 43 degrees Celsius
According to the Thai Ministry of Social Affairs and Digital Economy, from late March to mid-April, the northern regions of the country could record temperatures of up to 42-43 degrees. This is an extreme heat level, seriously affecting people's health and daily activities.
Weather forecast shows that many areas of Northern Thailand will have heavy fog in the early morning in early March, while other areas will experience hot days.
From late March to mid-April, the low pressure and monsoon from the Gulf of Thailand will make the weather hot and humid, with the risk of thunderstorms with strong gusts of wind.
From mid-April to mid-May, the weather will continue to be hot, but more thunderstorms will help cool down some.
Vietnam: Severe heat and extreme weather
According to the Vietnam National Center for Hydro-Meteorological Forecasting, global temperatures are on the rise, leading to the possibility that Vietnam will face more severe heat waves this summer.
Hot weather may appear from March to April, mainly in the Northwest, North and Central regions. From May, the number of hot days in the North and Central regions will increase.
Central Highlands and Southern regions: Hot weather is likely to appear later, with fewer hot days than in 2024. From April, rain may appear early and increase, helping to reduce temperatures.
Japan: Summer 2025 will be hot but not break records
The Japan Meteorological Agency (JMA) forecasts that temperatures from June to August 2025 will be higher than the average of the past 30 years. However, this year's heat may not reach the record level of 2023 and 2024.
From May, high temperatures may appear early, increasing the risk of heatstroke. From June onwards, the high pressure systems of Thailand and the Pacific will strengthen, pushing temperatures across the country up.
Although the summer of 2025 will be very hot, experts say it is unlikely to break last year's records due to changes in the West winds and global sea surface temperatures.
India: Bengaluru experiences an unusual summer
In February this year, Bengaluru - a place with a temperate climate - is experiencing unusually high temperatures, up to 35.9 degrees, nearly 9 degrees higher than New Delhi. Weather forecast shows that the summer of 2025 in Bengaluru may be hotter than last year.
Factors that make Bengaluru hotter include a lack of cold winds from the North, affected by the La Nina phenomenon.
Global: 2025 is expected to be one of the three hottest years in history
The global forecast from the UK Meteorological Agency shows that 2025 will be in the top 3 hottest years ever, only behind 2024 and 2023.
The average global temperature in 2025 is expected to be 1.29 - 1.53 degrees Celsius higher than in the pre-industrial period. This will be the 12th consecutive year that global temperatures will be 1 degree Celsius above pre-industrial average.
