Overview

• The Met Office long-range outlook for June 11–25 predicts changeable conditions with Atlantic systems interspersed by dry, sunny periods.
• Netweather charts indicate temperatures in south-east England could peak at 27 °C to 29 °C around 3 pm on June 11.
• Meteorologists emphasize that a northward shift in the jet stream—not an Iberian or Caribbean current—is driving the anticipated warmth.
• Wetter spells are most likely in north-west regions while the south and south-east benefit from drier interludes and potential hot spells.
• Forecast confidence drops beyond mid-June, raising the risk of cooler, unsettled weather and possible thunderstorms during any heat spikes.
