英国本周将经历第五次热浪，其中周三和周四气温预计在30摄氏度中段，周三中部部分地区可能达到36摄氏度，周四最可能成为本周最热的一天[1]。英国气象部门正考虑发布罕见的琥珀或红色极端高温预警[1]。当前，黄色热健康预警已在英格兰中部、东部、西南部、伦敦等8个地区生效，持续至周二晚9点[1]。
预警背后的影响范围广泛。超过2500万人面临用水限制，包括东南水务和泰晤士水务的所有客户[1]。极端高温预计将对铁路和电力网络造成潜在影响[1]，卫生部门警告易感人群面临健康风险[1]。英格兰和威尔士经历了有记录以来最干燥的7月[1]，威尔士和英格兰半数地区处于干旱状态[1]。
从更广的时间维度看，今年已录得多项创纪录数据。周日是今年第34个气温超过30摄氏度的日子，与1995年创造的纪录持平[1]。欧盟哥白尼地球观测计划报告显示，6月至7月西欧平均气温达21.61摄氏度，打破2022年纪录[1]。此外，今年夏季已造成2800多例超额死亡，与5月和6月创纪录热浪有关[1]。
Britain is bracing for another surge of extreme heat this week, with temperatures forecast to reach 36 degrees Celsius or higher as the country faces its fifth heatwave of the summer [1]. Wednesday and Thursday are expected to see temperatures in the mid-30s Celsius range, with Wednesday potentially hitting 36 degrees in central regions, though Thursday is likely to emerge as the hottest day of the week [1]. The UK's meteorological authorities are considering issuing rare amber or red extreme heat alerts, which could trigger significant disruptions to rail networks and power infrastructure [1].
The health consequences of this prolonged hot weather are mounting. Yellow heat-health alerts have already been activated across eight regions including central and eastern England, the southwest, and London, remaining in effect until Tuesday evening [1]. More than 25 million people face water use restrictions imposed by major suppliers including Southeast Water and Thames Water [1]. Health officials have warned vulnerable populations face serious health risks during the extreme heat. Sunday marked the 34th day this year when temperatures exceeded 30 degrees Celsius, matching the record set in 1995 [1]. Additionally, the summer of 2026 has already been linked to over 2,800 excess deaths, attributed to record-breaking heatwaves in May and June [1].
The broader context reveals an unprecedented climatic situation. England and Wales experienced their driest July on record [1], while the Copernicus Earth Observation Programme reported that average temperatures across Western Europe from June through July reached 21.61 degrees Celsius, surpassing the previous 2022 record [1]. Drought conditions now affect roughly half of Wales and England [1].
