Met Office Gives Verdict on June Heatwave as Temperatures Set to Hit 34°C
The Met Office has issued its official verdict on the June heatwave sweeping across the UK, with temperatures forecast to reach 34°C in parts of England later this month. After a cold and rainy start to June, weather maps are glowing red as a significant warm spell is expected to arrive from mid-June, bringing prolonged sunshine and above-average temperatures for much of England and Wales.
According to the latest forecasts from the Met Office and independent weather service WXCharts, temperatures will climb steadily from next week. Thursday June 18 is expected to see highs of 27°C, rising to 32°C on Monday June 22 and Tuesday June 23. Some isolated areas in southern England could even nudge towards 34°C, particularly in London, the South East, and East Anglia.
Meteorologist Annie Shuttleworth said: "It's worth noting at this point, although it is going to be a warm weekend, we're not expecting temperatures anywhere close to the May heatwave temperatures, but they certainly will be above average and higher than they have been recently." She added that UV levels and pollen levels will also be high as temperatures rise.
The Met Office's long-range forecast for June 16 to June 25 states: "A changeable period is likely through the middle of next week with outbreaks of rain focused across the north and northwest, some of which could spread to parts of the south and southeast at times. Some strong winds could accompany this, although with temperatures generally above normal. Into the following weekend, high pressure will probably become more dominant with conditions turning more widely dry and settled, and probably very warm for many, especially in the south."
Seven Counties Set to See Temperatures Above 30°C
The Met Office has identified seven counties that are expected to experience temperatures above 30°C during this warm spell:
- London
- Sussex
- Hertfordshire
- Essex
- Norfolk
- Suffolk
- Kent (Essex appears twice in some reports)
These areas will see the mercury rise well above the June average, with isolated spots potentially hitting 34°C. While the Met Office has clarified that this does not technically constitute a heatwave under its official definition—which requires three consecutive days of above-threshold temperatures—the spell will bring very warm or hot conditions across a wide area.
What the Weather Maps Show
High pressure is forecast to build across the east and southeast of England, drawing warm air from the continent. WXCharts projections show large swathes of England and Wales basking in highs of the mid-to-high 20s, with London, the South East, and East Anglia potentially breaching 30°C. Scotland and Northern Ireland will remain considerably cooler, with temperatures generally in the mid-teens to low 20s.
Context: How This Compares to May’s Record-Breaking Heatwave
Last month, the UK experienced a record-breaking May heatwave, with temperatures soaring to 35°C in some areas—unusually high for the time of year. Beaches were packed, and public health warnings were issued as the country baked in some of the hottest May weather on record.
This June warm spell, while significant, is not expected to reach those extremes. The Met Office has been careful to manage expectations, noting that although it will be above average, it will not be as intense as the May heatwave. However, the combination of high UV levels and elevated pollen counts could still pose risks, particularly for those with respiratory conditions or allergies.
The May heatwave was driven by a similar high-pressure system that brought dry, settled weather and prolonged sunshine. That event triggered widespread discussion about climate change and the increasing frequency of extreme weather in the UK. According to the Met Office’s three-month outlook, the chance of a hot summer is higher than normal, suggesting that further warm spells could follow as the summer progresses.
Why This Week Matters: Public Health and Travel
As temperatures rise, public health officials will be monitoring the situation closely. The UK Health Security Agency has previously issued heat-health alerts during similar warm spells, reminding the public to stay hydrated, avoid the sun during peak hours, and check on vulnerable neighbours. The current warm spell is expected to coincide with the school summer term coming to an end, meaning families may be planning outdoor activities and trips to the coast.
Transport networks could also be affected. Rail operators often impose speed restrictions during hot weather to prevent tracks buckling, and motorists are advised to carry water and plan journeys carefully. The Met Office has not yet issued any formal heatwave warnings, but the situation is being monitored.
Perspective: Broader Implications and Long-Term Trends
The June warm spell comes against a backdrop of growing concern about climate change and its impact on UK weather patterns. The Met Office’s three-month outlook, which suggests a higher-than-normal chance of a hot summer, is consistent with long-term trends showing that British summers are becoming warmer and drier on average. This has significant implications for agriculture, water resources, and public health.
Farmers are already feeling the effects. The dry conditions brought by the May heatwave led to concerns about crop yields, particularly for soft fruits and arable crops. While June’s warm spell may benefit some crops like barley and wheat, it could exacerbate water shortages in already dry regions. The National Farmers’ Union has previously called for better water management strategies to cope with increasingly variable weather.
Water companies are also under pressure. Reservoirs in parts of southeast England are still recovering from the 2022 drought, and a prolonged hot spell could lead to hosepipe bans and increased demand on supplies. The Environment Agency has been closely monitoring river flows and groundwater levels.
Broader Trends: Is This the New Normal? Climate scientists say that while individual weather events cannot be directly attributed to climate change, the overall trend is clear. The UK is experiencing more frequent and intense heatwaves, with the hottest days becoming hotter and lasting longer. The Met Office’s State of the UK Climate report has documented a clear warming trend over recent decades, with 2022 being the first year on record that temperatures exceeded 40°C.
For most people, a warm June is welcome news after a cold and wet start to the month. But the broader implications—for health, infrastructure, and the environment—are increasingly hard to ignore. As the UK braces for what could be another hot summer, the Met Office’s verdict on this June heatwave serves as a reminder that the season of extreme weather is now well underway.
Global Context: Heatwaves Across the Northern Hemisphere
This June warm spell is not unique to the UK. Large parts of Europe are also experiencing above-average temperatures, with heatwaves reported in France, Spain, and Italy. The global climate system is currently in a phase of heightened activity, with El Niño conditions contributing to extreme weather across the Northern Hemisphere. As the ICC Women’s T20 World Cup 2026: Expanded 12-Team Format Kicks Off in England gets underway, organisers will be keeping a close eye on the weather to ensure players and spectators remain safe.
While the Met Office has ruled out an official heatwave for now, the coming week will bring plenty of warm, sunny weather—and with it, the need for caution and preparation. The UK has learned from past heatwaves, and authorities are better equipped than ever to respond. But as temperatures climb, the message is clear: enjoy the sun, but stay safe.
