Overview

• Temperatures are forecast to peak at 29°C on Thursday, with isolated areas potentially reaching 30°C, marking the earliest 30°C day on record if achieved.
• The warm spell is driven by a high-pressure system creating 'home-grown' heat, with much of England and Wales experiencing highs significantly above seasonal averages.
• Northern Scotland is expected to see occasional rain, while the rest of the UK will remain largely sunny and dry, with cooler breezes on eastern coasts.
• Authorities have issued warnings for high pollen and UV levels, along with risks of wildfires and cold water shock as people head outdoors to enjoy the weather.
• The warm conditions follow a dry spring, with rainfall deficits raising environmental concerns, though showers and cooler temperatures are expected by Friday.
