Recently, Hainan has been experiencing high temperatures and little rain. Rumors such as "This year's abnormally high temperature is directly related to global warming or the El Niño phenomenon" and "This year's precipitation has hit a record low" have appeared on the Internet, attracting widespread attention. In this regard, experts from the Hainan Provincial Climate Center gave an interpretation. From October 2025 to January 2026, the equatorial central and eastern Pacific Ocean was in a La Niña state. It is currently in the transition stage from La Niña to El Niño, and an El Niño event has not yet formed. Therefore, this year's abnormally high temperature in Hainan is not directly related to the El Niño phenomenon.
The real reason lies in the superposition of three meteorological factors: the stronger subtropical high pressure, the influence of southwest hot and dry airflow, and the foehn effect. The airflow heated up sharply after crossing the Wuzhishan Mountains, coupled with the warming effects of clear sky exposure and downdrafts, resulting in extremely high temperatures in Qiongbei and Qiongxi.
In response to the statement that "Hainan's precipitation this year has hit a record low," experts from the Hainan Provincial Climate Center clearly responded that this statement is not consistent with the actual situation. Data show that as of April 7 this year, the precipitation in Hainan Province was 31.1 mm, which was about 70% less than the same period in normal years and the second lowest value for the same period in history; the year with the least precipitation during the same period in history was 1971, with only 30 mm of precipitation.
The current high temperature weather is mainly dry and hot with low humidity, and the feeling of exposure and burning is particularly obvious in the afternoon. Experts remind the local public to take sun protection and cooling measures.
