Hong Kong is experiencing an unusually warm Lunar New Year’s Eve, with the local weather service reporting a record-breaking minimum temperature for the final day of the Chinese lunar calendar. This significant temperature reading is part of a broader trend of warming weather patterns impacting the region.
Unprecedented Warmth on Lunar New Year’s Eve
On Lunar New Year’s Eve, the Hong Kong Observatory recorded a minimum temperature of 22.0 degrees Celsius. This figure marks the highest temperature ever logged for this specific day in the lunar calendar, highlighting a departure from typical seasonal conditions.
The Observatory had previously forecast a high of 28 degrees Celsius for Monday, Lunar New Year’s Eve itself. This followed a Sunday that saw temperatures reach 26.9 degrees Celsius, equalling a previous record for the 28th day of the 12th lunar month. This particular day is traditionally observed as a time for “year-end cleaning” in Chinese culture. The previous instance of 26.9 degrees Celsius on this day was recorded in 2010.
The Observatory noted that weak winds were present over Guangdong, and locally, temperatures on Monday morning were one to two degrees higher than the previous day.
Looking Ahead: The Lunar New Year Forecast
The forecast for Lunar New Year’s Eve predicted sunny periods throughout the day, with the possibility of one or two showers occurring at night.
However, a shift in weather is expected. A fresh to strong northeast monsoon is anticipated to reach Hong Kong between Monday night and the early hours of Tuesday, according to the weather service.
Temperatures During the Festival
For the initial three days of the Lunar New Year celebrations, the maximum temperature is projected to remain around 22 degrees Celsius. The Observatory also indicated that the mornings of the second and third days of the holiday period are expected to be cool. The weather is forecast to become warmer again as the weekend approaches.
The Broader Context of Climate Change
These record-breaking temperatures in Hong Kong are occurring against a backdrop of global climate change. The Intergovernmental Panel on Climate Change (IPCC) has issued stark warnings regarding the escalating intensity and frequency of heatwaves since the mid-20th century. This trend is attributed to human activities and the subsequent increase in greenhouse gases, such as carbon dioxide, which trap heat in the atmosphere and elevate global surface temperatures. The consequence is the emergence of hotter and longer heatwaves, posing significant risks to human life.
Research from the NGO Berkeley Earth indicates that Hong Kong has already experienced a warming of 1.7 degrees Celsius since the Industrial Revolution. Furthermore, a 2023 study suggests that by the end of this century, heat and humidity levels in some parts of the world could reach lethal thresholds for extended periods, rendering outdoor activities impossible. This phenomenon underscores the urgent need to address climate change and its far-reaching implications for regional and global weather patterns.
