It predicted that up to eight tropical cyclones will enter the city’s 500-kilometre warning radius from June or earlier.
The forecaster also said Hong Kong will be affected by rainstorms and localised heavy rain, despite predicting annual rainfall to be within the normal range.
“In general, the temperatures in Hong Kong are on a rising trend in the past few years. In fact, in the last year, we have the highest wind temperature in Hong Kong. And it’s a result of urbanisation and also the effect of climate change,” said observatory director Chan Pak-wai.
Looking back at 2024, the observatory noted that it was the warmest year recorded globally, and that Hong Kong also recorded 11 months that were warmer than usual.
The annual mean maximum and minimum temperatures were 27.3 and 22.8 degrees Celsius respectively, which were the highest and second highest on record.
The forecaster also pointed out that sudden changes in the weather like on March 15, when it issued a hail warning and the first Amber rainstorm warning signal this year, are common in spring.
Chan said people should take note of push notifications from the observatory’s mobile app to get immediate weather updates.
