It's 1 1 month. The weather in Taipei is as hot as Haikou, sometimes even hotter than Haikou. Is it abnormal?

Taipei is special, the urban area is basin-shaped, and the warming effect is obvious. However, the temperature in the whole Taipei area is not enough to be divided into tropical monsoon climate. The climate is still determined by vegetation, which is the comprehensive data of many years, not a certain year. Rubber can't grow in Taipei, and coffee can't bear fruit. Recently, the subtropical high is relatively strong, and the eastern part of China is warmer than normal. In fact, to be precise, Taipei belongs to the south subtropical monsoon climate, while Haikou belongs to the north tropical monsoon climate, and the difference between them is relatively small.
