Weather forecast for the Hung Kings Commemoration Day
According to the National Center for Hydro-Meteorological Forecasting, from April 25 - 27 (ie, the Hung Kings Commemoration holiday), the Northern region will be cloudy, with showers and thunderstorms in some places, especially from April 26 - 27, rain tends to increase, concentrated in the late afternoon and night. Temperatures fluctuate around 23 - 29 degrees Celsius, the weather is quite cool, favorable for pilgrimage activities.
Meanwhile, the area from Thanh Hoa to Hue has scattered showers, while the Central and Southern regions maintain sunny days, with localized thunderstorms in the evening. The meteorological agency also warns of the risk of tornadoes, lightning, hail and strong gusts of wind during thunderstorms.
Notably, the rain diễn biến in the North - especially Viet Tri (Phu Tho) - during this occasion continues to repeat the weather pattern for many years. The typical rainy weather is associated with the folk phenomenon called "river washing temples" - a familiar characteristic of every Giỗ Tổ season.
According to folk beliefs, "river to wash temples" are rains that appear before or after the 10th day of the 3rd lunar month, said to be "washing away mortal dust", purifying the sacred space, welcoming descendants to offer incense to commemorate the Hung Kings. After the ceremony, rain reappears as if to restore tranquility to the relic site.
In fact, this phenomenon usually occurs in about 2-3 days before or after the main festival, with the characteristic of short showers and thunderstorms, not prolonged.
From a scientific perspective, meteorologists believe that "rain washes temples" is not a spiritual factor but a coincidence with weather laws. March of the lunar calendar (corresponding to April of the solar calendar) is the transitional period in the North, when weak cold air still affects, combined with increased temperature, easily causing showers and thunderstorms with a high probability, up to about 50%.
In addition, the terrain of the Hung Temple area with Nghia Linh mountain and surrounding valleys also contributes to the formation of convection currents, creating thunderstorms and causing localized rain - making this phenomenon more likely to be repeated over many years.
