HK Heatwave Hits 39.3°C Driven by Tropical Cyclone Dolphin

Tropical Cyclone Dolphin is driving extreme heat across Hong Kong through its outer bands, pushing temperatures above 37 degrees Celsius in multiple districts on Monday, according to the Hong Kong Observatory (HKO). As the storm tracks across eastern China, meteorologists warn that the oppressive conditions will likely persist for another day or two.

Extreme Temperatures Recorded Across Hong Kong Districts

Temperatures spiked significantly during the midday hours on Monday. According to the Hong Kong Observatory, Sheung Shui reached a scorching 39.3 degrees Celsius around noon. Meanwhile, Wong Tai Sin registered 38 degrees, and at least seven other districts crossed the 37-degree threshold.

Senior scientific officer Cheung Ping stated that while Tropical Cyclone Dolphin made landfall in Zhejiang on Sunday, its broad outer circulation continues to impact the Guangdong coast. This system is combining with a southwesterly airstream that is carrying hot inland air toward the territory.

Weather Forecast and Shifting Conditions

The intense heat will not last indefinitely. According to Cheung Ping, the weather is expected to turn more unstable later in the week due to an approaching upper-air disturbance. This shift should bring slight relief to residents in the form of a few showers.

Looking further ahead, HKO officials are monitoring broader climatic patterns. Cheung noted that sea surface temperatures in the central and eastern Pacific have risen over the past few months. These rising temperatures could develop into a strong El Niño phenomenon persisting through November and December.

According to scientific projections, this potential El Niño could rank among the strongest on record. Such an event has the potential to keep Hong Kong warmer than usual over the next two years.

Health Risks and Safety Precautions During Extreme Heat

Medical professionals have issued strict warnings regarding the dangers of outdoor exposure during these high temperatures. An emergency physician surnamed Yeung stated that participating in outdoor activities in extreme heat significantly increases the risk of heatstroke and heat exhaustion.

According to Yeung, the mortality rate for heatstroke exceeds 10 percent. Symptoms of heat exhaustion include heavy sweating and chills. Individuals experiencing these symptoms should seek shade immediately and reduce physical activity.

Vulnerable populations face heightened dangers during severe heatwaves. Yeung cautioned that children—whose cooling mechanisms are not yet fully developed—along with the elderly, pregnant women, and obese individuals, face substantially higher health risks when exposed to extreme temperatures.

Frequently Asked Questions

Sheung Shui reached 39.3 degrees Celsius around noon, Wong Tai Sin recorded 38 degrees, and at least seven other districts exceeded 37 degrees.

When will the hot weather subside?

The Hong Kong Observatory warns that the hot weather may persist for another day or two, though an upper-air disturbance is expected to bring slightly more unstable weather and a few showers later in the week.

Who is most at risk during extreme heat conditions?

According to emergency physician Yeung, children, the elderly, pregnant women, and obese individuals face higher risks of heat-related illnesses like heatstroke and heat exhaustion.
