The ongoing humidity in northern Vietnam is expected to linger until April, the Vietnam News Agency quoted Nguyen Van Huong, an official from the National Center for Hydro-meteorological Forecasting, as saying.
February is the middle of winter in northern Vietnam, so the cold spell still has a strong impact on the region, the weather expert elaborated.
The dry air in the region is usually replaced by humidity starting February, and the common weather patterns are light rain, drizzle, fog, and low temperatures at night and early in the morning.
Such weather typically lasts from February to April, characterized by humidity of up to 80 percent, drizzle, and fog.
It ends when the northeast monsoon dominates the weather in northern provinces.
The humid weather can interfere with daily activities and adversely affect the health of local residents.
High humidity is a favorable environment for all kinds of respiratory pathogens and allergies, especially for young children and the elderly.
It is also a favorable condition for pests and diseases such as late blight and aphids, which damage crops and vegetables.
It is recommended that residents keep their doors closed, switch the air conditioner to dry mode, use dehumidifying materials such as old newspapers and charcoal or dehumidifying equipment, and wipe the house with a dry rag.
Farmers should make a plastic frame to shield vegetables, fertilize plants to increase resistance, clean the field, use insecticides, and check the leaves regularly to detect aphids.
