Japan's Shikoku Region Freed from Seasonal Rains 5 Days Earlier Than Normal

The Shikoku region, one of Japan's four main islands, has left the seasonal rain period behind. According to a statement made by the Takamatsu Regional Meteorological Observatory, it was officially announced on 12 July that the rainy season in the region has ended. It was stated that this date occurred exactly five days earlier than the normal period, which is the long-term annual average. However, when compared to the end date of the seasonal rains last year, this year is seen to be approximately fifteen days later. It was recorded that the region entered this year's rainy season around 2 June.

During the period between 2 June and 11 July when the seasonal rains affected the region, very high rainfall measurements were recorded. According to the preliminary report data of the said process, 452.0 millimeters of precipitation fell in the city of Takamatsu in Kagawa Prefecture. In Tokushima city, the total rainfall was measured at 457.5 millimeters. While this figure reached 569.5 millimeters in the city of Matsuyama in Ehime Prefecture, a very high level of 748.0 millimeters was seen in Kochi city. It has been confirmed that all these measurements in the region significantly exceeded the historical averages and normal rainfall levels.

When the near-term weather forecasts are evaluated, the Shikoku region is expected to enter a hot and sunny period. According to information obtained from meteorology officials, the region will come under the influence of the Pacific high-pressure system in the upcoming one-week period. Due to this atmospheric structure completely surrounding the region, it is anticipated that generally sunny and clear weather will prevail. In line with seasonal norms, temperatures are likely to rise and sultry weather is expected to begin. This situation will provide more favorable conditions for outdoor activities for the local community.

The Japan Meteorological Agency closely monitors the start and end dates of seasonal rains in different regions of the country and regularly announces them to the public. In this context, the estimated dates are initially presented to the public quickly as temporary notifications. The agency scientifically evaluates the general weather statistics of the entire year and especially the autumn period. It is stated that the process of fully finalizing and reviewing the data is completed in September every year, and the dates are ultimately finalized. This meticulous examination process also helps in better understanding climate changes and regional weather events.

The early end of the seasonal rains can have various impacts in a country like Japan, which has high humidity levels during the summer months. The shortening of the rainy period may create different pressures on the irrigation needs of agricultural activities, as well as affect the levels in dams and water storage systems. On the other hand, receiving more rainfall than expected indicates that water resources are already filling up strongly, reducing the potential drought risks during the summer months. With the arrival of sunny weather, local residents will begin to take necessary precautions against heatwaves. Weather forecasts and seasonal transitions in Japan continue to be of critical importance across a wide spectrum, from the daily lives of the public to the agricultural sector.
