Warmest Days of the Year Expected Tuesday and Wednesday, Temperatures Soar

Just days after Storm Dave battered the UK with 70mph winds and widespread disruption over the Easter weekend, a dramatic turnaround is underway. London and south-east England could reach temperatures of 21C or 22C on Tuesday, rising to 24C on Wednesday, while Manchester could hit 20C.

BBC lead weather presenter Simon King says brisk south-easterly winds are drawing in much warmer air from the European continent, pushing temperatures across the UK six to ten degrees above the average for early April. Combined with plenty of sunshine, Tuesday is likely to be the warmest day of the year so far. Wednesday is then forecast to push even higher, making it the hottest back-to-back stretch of 2026.

Deeside is set for its warmest days of 2026 this week, with Hawarden forecast to reach 19C on Wednesday before a significant drop in temperature on Thursday. For Hawarden, the forecast shows 18C on Tuesday, rising to 19C on Wednesday, with sunshine and light winds through the middle of the day. Wednesday's peak is expected between 1pm and 4pm.

The warmth arrives on the heels of one of the stormiest Easter weekends in recent memory. Around 2,000 households in Northern Ireland were left without power on Saturday as Storm Dave swept through the region with strong winds. The short period of settled weather replaces the rain and 70mph winds that battered parts of northern England, Scotland, Wales and Northern Ireland.

According to BBC Weather's lead weather presenter Simon King, a warmer southerly wind will push temperatures to around 6 or 7 degrees above average on Wednesday. That magnitude of departure from seasonal norms is unusual for early April, when daytime highs would typically sit well below 20C across most of Britain.

The respite, however, will be brief. Temperatures are forecast to fall sharply by Thursday, signalling that the settled spell is a fleeting window rather than the arrival of sustained spring warmth.
