Are you looking for the master of prophecy?

But there are data from previous years, you can refer to it.

First, April is the transitional period of spring and summer, which is obviously manifested in the retreat and gradual disappearance of the northeast monsoon and the emergence and gradual development of the southeast monsoon. The atmospheric circulation almost stops, and the number of still winds (that is, winds without direction) is particularly high, accounting for 17 times in the whole month, while the southeast wind only has 13 times. Generally speaking, there are more quiet days than southeast winds.

Second, the temperature rises the most in the monthly warming throughout the year, such as 3.2℃ higher in March than in February and 4.2℃ higher in April than in March. This is the month with the largest temperature rise in the whole year. Therefore, the thermal reaction is very sensitive. Judging from the temperature rise in April, if the temperature in April is higher than that in June 10, the continental climate is strong, while in Xiamen, on the contrary, if the temperature in June is higher than that in April, the maritime climate is strong (April represents spring, and June 10 represents autumn), but this is only one of the bases of maritime climate. If compared with Tongan and Zhangzhou, Xiamen's temperature rise is slower than Tongan and Zhangzhou, because these two places are inland and the temperature rise is faster than Xiamen's, which also shows that Xiamen's maritime climate is stronger than theirs.

Thirdly, the rainfall in April in Xiamen is more than that in March, and the monthly rainfall can reach 124 mm, which is more than the three months of 1, 2 and 3 in the first half of the year and more than the three months of September, 10, 165438 and 12 in the second half of the year. Rainy days have also increased. 24 solar terms's "Grain Rain" on the 20th of this month indicates the second rain in a year. According to the weather proverb, "it rains a lot in Qingming Festival". It also shows that this month's rainfall process started as early as the beginning of April, so it is more rainy than March. It can reach 19-20 days.

Therefore, it is normal for it to rain in April.
