This Year’s ‘Sanjiu’ Wasn’t Cold—Will It Get Cold Later?‘Sanjiu’ refers to the period from the 19th to the 27th day after the winter solstice and is traditionally considered one of the coldest times of the year in China. However, in recent years, due to global climate change and abnormal atmospheric circulation, some regions have experienced unusually mild temperatures during Sanjiu, leading to what’s known as a ‘warm winter.’ This has raised questions: if Sanjiu wasn’t cold, does that mean the rest of winter won’t be cold either?Meteorological experts clarify that Sanjiu is just one phase of winter, and its temperature alone cannot determine the overall winter trend. Even if Sanjiu is warmer than usual, strong cold air masses can still move in later, causing sharp temperature drops or even late-season cold snaps known as ‘false springs.’ Factors such as intensified Siberian high pressure, southward surges of polar air, or La Niña events can all trigger significant cooling after Sanjiu.Therefore, a mild Sanjiu doesn’t guarantee a mild remainder of winter. The public should continue monitoring medium- to long-range weather forecasts issued by meteorological authorities and remain prepared for sudden cold spells by dressing appropriately and taking necessary precautions to protect health and safety.
今年‘三九’不冷，后面还会冷吗？‘三九’通常指冬至后的第19天到第27天，是一年中最冷的时段之一。然而，近年来受全球气候变化和大气环流异常影响，部分地区在‘三九’期间气温明显偏高，出现‘暖冬’现象。这引发了不少人对后续天气走势的疑问：‘三九’不冷，是否意味着整个冬天都不冷了？气象专家指出，‘三九’只是冬季的一个阶段性节点，其气温不能完全代表整个冬季的冷暖趋势。即使‘三九’偏暖，后期仍可能出现强冷空气活动，导致气温骤降，甚至出现‘倒春寒’等极端天气。例如，冷空气南下、西伯利亚高压增强或拉尼娜现象等因素，都可能在‘三九’之后带来显著降温。因此，‘三九’不冷并不等于冬天结束或不会再冷。公众应持续关注气象部门发布的中长期天气预报，合理安排生活与出行，做好防寒保暖准备，以防突如其来的寒潮影响健康与安全。
