Core Viewpoint - The upcoming 2025 National College Entrance Examination (Gaokao) is expected to be affected by significant rainfall, particularly in southern China, which raises concerns among students and parents about the impact on exam performance and logistics [1][2][3]. Weather Impact on Gaokao - The China Weather Network predicts a new round of rainfall in southern regions during the exam period, with 16 out of 31 provincial capital cities having a precipitation probability exceeding 30% [2][10]. - Historical data shows that cities like Guiyang, Guangzhou, and Haikou have the highest rainfall probabilities during the exam days, at 64.3%, 60.8%, and 55% respectively [9][10]. - The phenomenon of "it always rains during Gaokao" is not merely coincidental but is closely linked to China's unique climatic patterns, particularly the onset of the monsoon season in early June [14][15]. Climatic Conditions - The summer monsoon significantly influences weather patterns in East Asia, leading to concentrated rainfall during the exam period, which coincides with the peak of the rainy season [15][17]. - The "plum rain season" in southern China, characterized by continuous rain and high humidity, aligns with the timing of the Gaokao, further contributing to the perception of frequent rain during exams [18][20]. Historical Context - Prior to 2003, the Gaokao was held in July, but high temperatures posed a greater risk to students than rainfall, leading to the decision to move the exam to June [20][21]. - Statistical analysis from 1981 to 2019 indicates that around 70% of provincial capitals maintain average maximum temperatures between 25-30°C during the exam days in June, making it a more suitable time compared to July when temperatures often exceed 30°C in 60% of cities [21][22][24]. Psychological Perception - Extreme weather conditions, such as high temperatures and heavy rainfall, create a lasting impression on the public, reinforcing the stereotype of "Gaokao must rain" over time [25]. - Understanding the natural climatic patterns can help students and parents approach the exam with a more composed mindset, focusing on preparation rather than weather concerns [26][27].
