The UK is set for a sharper warm-up by the end of the week after a cool, wet start to June, but an official heatwave verdict is still out of reach. High pressure is building and most places should turn drier and sunnier, with the warmest conditions expected in England and Wales.
That is why people are checking the met office june heatwave verdict now: after days of rain and below-average temperatures, the country could be heading into a brief burst of proper summer warmth. On Wednesday, heavy showers are expected across the UK, with some thundery downpours in eastern Scotland and eastern England, and temperatures around 3 to 6C below average. Thursday stays unsettled too, as a large area of rain pushes in from the west across many parts of the UK.
Friday should be a step change, turning drier, brighter and slightly warmer. By the weekend, high pressure is expected to build gradually from the south, setting up the chance of a much warmer spell. Some weather models bring high pressure right across the UK and allow southerly breezes to develop, which could lift temperatures to 25 - 27C in parts of England and Wales, around 6-8C above average for June. Under that scenario, Scotland and Northern Ireland would also turn milder, with low-twenties Celsius likely.
But that is not the only outcome. Other models keep the high pressure farther west or south-west of the UK, leaving more of a north or north-westerly wind in place. That would hold temperatures lower, with the south more likely to sit in the low-twenties and the north in the teens. With the forecast still split, it is too early to say whether the warmth will last long enough, or arrive strongly enough, for a formal heatwave declaration.
For now, the best reading is simple: summer warmth is on the way, but the verdict depends on which forecast wins out. The next important update is the weekend outlook, when forecasters will know whether the UK has only a brief warm spell or the first official heatwave of June.
