The Met Office has issued a heatwave warning for parts of the UK, with temperatures potentially reaching 34C in the South East. However, forecasters stress that this July heatwave will feel different from June's record-breaking spell, citing five key differences.
Five Ways July's Heatwave Will Be Different
According to the Met Office, the upcoming heatwave will not be a repeat of June's extreme conditions. Here are the five ways it will differ:
- Lower humidity: The air will be far less humid overall, avoiding the oppressive tropical nights experienced in June.
- Single temperature spike: Instead of sustained extreme heat, this week will see a lone peak, with temperatures building gradually from Tuesday.
- Peak temperatures lower: While June saw 38C in parts of England, this heatwave is forecast to peak at around 34C in the South East.
- Less intense feel: Despite above-average temperatures, the lower humidity will make conditions feel less stifling for most people.
- Health alerts possible but not guaranteed: Heat-health alerts have been issued for large parts of England, but officials have not ruled out further expansion later in the week.
Temperature Build-Up and Peak
The Met Office expects temperatures to climb steadily from Tuesday, initially close to seasonal averages before peaking later in the week. The highest temperatures are likely in the South East, where 34C is possible. This marks Britain's third heatwave of the year, following a brief but intense spell in June that reached 38C.
Health Risks and Precautions
While the forecast has ruled out a sudden blast of extreme temperatures, health risks remain. Heat-health alerts have been issued for large parts of England, and vulnerable groups are advised to take precautions. Local health services are on standby to protect those at risk, such as the elderly and those with pre-existing conditions.
Official Heatwave Definition
To officially qualify as a heatwave, a location must meet or exceed its specific local threshold—ranging from 25C across the north to 28C in London—for at least three consecutive days. The Met Office confirmed that this week's conditions are expected to meet these criteria in some areas.
