Strongest Cold Wave of Winter Approaching Guangdong
Countdown: 3 days! The strongest cold wave since the start of winter is about to hit Guangzhou, starting from the evening of next Tuesday. By then, the maximum temperature in Guangzhou will gradually drop to 16°C, while the minimum temperature in high-altitude mountainous areas of northern Guangdong will reach -4°C, with sleet or freezing rain (freezing).
Detailed Forecast for Guangdong
January 20th will mark the Major Cold (Da Han), the last of the 24 solar terms. Starting from January 17th, the first cold wave of 2026 will affect most areas in central and eastern China, bringing the strongest snow, rain and freezing weather process since winter began. It is expected that after this cold wave travels a long distance into Guangdong, it will weaken to a strong cold air mass, but its impact should not be underestimated.
According to the Guangdong Provincial Meteorological Observatory, most parts of Guangdong will be sunny to cloudy from January 18th to 19th, with (light) fog in the morning and scattered drizzle in some cities and counties, and cool mornings and evenings. The front of strong cold air from the north will affect northern Guangdong on the morning of January 20th, central Guangdong around evening, and southern coastal areas at night. The average temperature drop during the process: 7~10°C in northern Guangdong, 5~7°C in central Guangdong, and 3~5°C in southern coastal areas. The lowest temperature of the process will occur around January 22nd. From January 21st to 23rd, there will be widespread low temperatures below 5°C in northern Guangdong, with -4~0°C in high-altitude mountainous areas of northern Guangdong, accompanied by sleet or freezing rain (freezing).
The Guangzhou Meteorological Observatory predicts that Guangzhou will be mainly sunny and dry from January 18th to the daytime of January 20th, with slightly more cloud cover at times, light fog in the morning and evening, and a steady and slight rise in temperature, maintaining a large temperature difference between day and night. Starting from the evening of January 20th, strong cold air will affect Guangzhou from north to south, with increased northerly winds and a significant drop in temperature.
Will the Temperature Drop Bring Rain?
Due to low humidity in the middle and lower layers of the atmosphere, this cold wave will not bring significant rainfall. Scattered drizzle or sleet is expected mainly in Shaoguan and Qingyuan in the northwest, while other areas will see increased cloud cover with isolated scattered drizzle.
Health Tips: Don't Get Up Too Suddenly in Winter
When the weather turns cold, many people find it difficult to get out of bed in the morning. This seemingly "lazy" habit actually has implications for cardiovascular health. Doctors advise: stay in bed for an extra 10 minutes in winter for better health.
Recently, Mr. Wang, a 58-year-old hypertension patient in Wuhan, suddenly sat up as soon as his morning alarm went off, and immediately felt dizzy and black spots in front of his eyes. After examination at a community health service center, the doctor advised him "not to get up too suddenly" and reminded him to lie in bed for 10 minutes after waking up in winter and do some hand and foot stretches.
Doctors remind: "Staying in bed for 10 minutes in winter is more in line with the human circadian rhythm and the operating rules of the cardiovascular system." Sudden standing up may cause violent vasoconstriction and a sharp rise in blood pressure, which is harmful to the heart and cerebrovascular vessels.
Why do we want to stay in bed in winter? During sleep, the human body enters a "low-energy state": both heart rate and blood pressure decrease. In the early morning, especially in winter, the sudden drop in temperature triggers vasoconstriction, and at the same time, as the body transitions from rest to activity, blood pressure is prone to a sharp rise. If you suddenly get up at this time, blood cannot supply the brain and heart in time, which may lead to dizziness, black spots in front of the eyes, and even induce cardiovascular and cerebrovascular accidents. It can be seen that the desire to stay in bed in winter may be a "protective mechanism" activated by the body.
In addition, friends who have the habit of morning exercise should also be careful: morning exercise in winter should not be too early, especially for hypertension patients! Strenuous exercise in cold environments will increase the burden on the heart, leading to insufficient oxygen supply, cardiac ischemia, and even myocardial infarction. It is recommended to exercise after 10 am or in the evening, following the principles of "moderation, no fatigue, and persistence".
How to Stay in Bed Correctly? Remember These 4 Steps
- Wake up and lie still: After opening your eyes, keep lying flat and take several deep abdominal breaths. This helps increase blood oxygen levels and gently wake up the brain and body.
- Warm up in bed: Alternately clench and release your fists, and repeatedly flex and stretch your toes in the bed to promote peripheral blood circulation and prepare for getting up.
- Sit up slowly: Support your body with your arm in a side-lying position, then sit up slowly. Sit quietly on the edge of the bed for a moment to allow the cardiovascular system to gradually adapt to the blood supply needs in a sitting position.
- Stand up slowly: Place your feet on the ground and feel your body state. If there is no dizziness, black spots in front of the eyes or other discomfort, then stand up slowly.
Recently, the temperature difference between day and night is large, and it is cold in the morning and evening. Everyone should pay attention to adding or removing clothes in a timely manner. In addition, the dry weather also requires more attention to fire and electricity safety.
