Must replace air conditioner immediately in rainy season
"Is it really the rainy season yet? Why is it so hot at 9am, and still hot in the afternoon and evening on many days?", Ms. Thanh Thuy wondered as she traveled from District 7 to her company's office in the city center. According to Ms. Thanh Thuy, in recent days, the afternoon sky has been covered with thick dark clouds but in the end, the temperature remains around 37 - 38 degrees Celsius. Since the holiday, although there has been rain, it has been sparse so the sun is still intense.
Some people in Ho Chi Minh City still have to replace their air conditioners even though the hot season has passed.
Mr. Tuan An, residing in District 10, commented, "Although the recent rains have helped cool down a bit, the weather is still very hot. My house has to run the air conditioner almost 20/24 hours to be able to withstand the heat. Last month, the electricity bill was more than double the normal price. I thought that during the rainy season I could limit the use of air conditioners, but up to now it has not been reduced. Because the machine is old and consumes a lot of electricity, I had to replace it with a new one last week to save more in the long run."

According to weather monitoring applications on mobile devices, from 11am onwards, the meteorological temperature in Ho Chi Minh City was 34 - 36 degrees Celsius for 15 hours; and the perceived temperature was 39 - 41 degrees Celsius.
Explaining the current hot weather, MSc. Le Thi Xuan Lan, a hydrometeorological expert, said: Since May 12, the southwest monsoon has been more active; the entire Southern region has formed a typical weather pattern of the rainy season in the South, which is sunny in the morning and rainy in the afternoon. However, because it is still early in the season, the amount of rainfall is still quite limited, so the heat is still dominant. In addition, the strong activity of the Indo-Burma low pressure in the west also affects the current temperature in the South and Vietnam. "However, the hot weather during the day has narrowed compared to before, only from 9am to 3pm. Currently, the southwest monsoon is continuing to strengthen and the rain will gradually increase, accordingly the temperature will continue to decrease further," Ms. Lan said.
Average temperature increased by 0.5 - 1 degree Celsius
According to the National Center for Hydro-Meteorological Forecasting, in April 2023, the average temperature in the North, North and Central Central regions will generally be 1 - 1.5 degrees Celsius higher; in particular, the Northeast, South Central, Central Highlands and South regions will be 0.5 - 1 degree Celsius higher than the average of many years in the same period.
The sun is hot even though it is the rainy season.
In the first half of May 2023, the average temperature across the country was generally 0.5 - 1.5 degrees Celsius higher than the average of many years in the same period. Notably, the Northwest region, the provinces from Thanh Hoa - Quang Ngai, the Central Highlands were 1.5 - 2 degrees Celsius higher, in some places over 2 degrees Celsius higher than the average of many years in the same period.
Heat and total rainfall in April nationwide were generally 30-60% lower than the average for the same period in many years. In the first half of May, total rainfall in the North and South was mostly 30-80% lower than the average for many years.

It is forecasted that from now until the end of August, heat waves will continue to occur in the Northern and Central regions. The number of hot days this year will be higher than the average of many years and more severe than the same period in 2022.
The average temperature nationwide is generally about 0.5 degrees Celsius higher than the average of many years; in the Northern and North Central regions in the period of July - August 2023, it is generally 0.5 - 1 degree Celsius higher than the average of many years.
Total rainfall in most regions across the country from June to August 2023 is generally approximately the average of many years, especially in August, total rainfall in the Central Highlands and the South is generally 5 - 20% higher than the average of many years in the same period.
According to MSc. Le Thi Xuan Lan, the average temperature of the following year is always higher than the previous one, which is a trend that we still call the phenomenon of "global warming". The underlying cause is due to human socio-economic activities, especially the exploitation and use of fossil fuels, which create a lot of CO2 , making the atmosphere hotter. In addition, we are currently affected by El Nino (hot weather). El Nino not only causes prolonged heat and less rain, but also weather patterns such as EL Nino and La Nina that cause extreme weather. For example, summers will be hotter and longer, winters will also be colder and longer, and dry areas will also be drier.
