For example, the first 30\u00b0C of the year occurred in June in both 2024 (25 June) and 2025 (19 June), while in other years the threshold has not been reached until July or even August. <\/p>\n<p>How rare is 30\u00b0C in May?<\/p>\n<p>The last time a May day hit 30\u00b0C was in 2012, on 25 May. There were similarly high temperatures reported in 2010 (23 May) and 2005 (27 May), demonstrating that while uncommon, summer-like heat in May is not unprecedented.<\/p>\n<p>Looking back into history, temperatures reached 30\u00b0C or above in May in just a handful of years.<\/p>\n<p><a class=\"imagen \" href=\"https:\/\/www.yourweather.co.uk\/news\/forecasts\/uk-weather-maps-turn-red-15-zones-facing-saharan-air-as-temperatures-hit-33-c-over-the-bank-holiday-full-list.html\" title=\"UK weather maps turn red: 15 zones facing Saharan air as temperatures hit 33\u00b0C over the Bank Holiday \u2013 full list\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" fetchpriority=\"low\" class=\"lazy img-body non-editable\" src=\"https:\/\/www.europesays.com\/britain\/wp-content\/uploads\/2026\/05\/uk-weather-maps-turn-red-15-zones-facing-saharan-air-as-temperatures-hit-33-c-over-the-bank-holiday-.jpeg\"  width=\"320\" height=\"225\"\/><\/a><\/p>\n<p>Among the earliest instances recorded are 29 May 1944, 12 May 1945, 29 May 1947, and 25 May 1953. <\/p>\n<p>Overall, the pattern is clear: May 30\u00b0C events are sporadic rather than regular, typically separated by many years, the Met Office said. <\/p>\n<p>What\u2019s behind this weekend\u2019s heat?
