From 35.6°C to lying snow: the records June has to beat

If this week's cold soak has you doubting it's really summer, June's record book is on your side — and against you. No month in the UK calendar covers a wider stretch of possibility: the Met Office's June extremes review reads like four different climates taking turns.

The heat ceiling — and why it's wobbling

The UK's hottest June day remains 35.6°C at Southampton Mayflower Park on 28 June 1976, the benchmark of the drought summer that every British heatwave still gets measured against. Fifty years on it has survived everything the warming climate has thrown at it — but only just, and after May 2026 delivered the first 35°C+ reading in any May on record, forecast commentators are openly calling the 1976 mark vulnerable. If a ridge builds late this month, as the longer-range signal hints, watch that number.

The cold floor

The other end of June's range is genuinely startling:

• Lowest June minimum: −5.6°C — recorded at both Santon Downham (Norfolk) and Dalwhinnie (Inverness-shire). An air frost in meteorological summer, in East Anglia.
• Lowest June maximum: 5.1°C at Nunraw Abbey, East Lothian, on 2 June 1975 — a day that never reached six degrees.
• That same date, 2 June 1975, put 16 cm of lying snow at Glenmore Lodge in the Cairngorms. Snow stopped play at cricket grounds in England the same week.

For calibration: this Thursday's ensemble-mean temperatures near 11–12°C — the washout we covered this morning — sit comfortably inside June's historical envelope. The month has done far colder.

Water and wind

• Wettest June day: 212.8 mm at Honister Pass, Cumbria, on 28 June 2020 — a daily total that would be respectable for a month. Llechwedd Quarry in Gwynedd managed 196.8 mm as far back as 28 June 1928.
• Strongest June gust: 78 knots (89 mph) at Muckle Holm, Shetland, on 13 June 2000, with the Needles touching 73 knots (83 mph) on 23 June 2004 — proof that windstorm-grade gradients don't read the calendar, something last weekend's deep June low underlined at smaller scale.

And the consolation prize

The sunniest June day on record belongs to Baltasound, Shetland: 17.7 hours of sunshine on 26 June 1929 — a reminder that at this latitude, when June behaves, there is more chaseable daylight than any other month will give you.

That's the working range of the month we're in: 35.6°C to lying snow, 212.8 mm to 17.7 hours of sun. June doesn't do averages — which, for chasers, is rather the point.
