Recent Met Office and ECMWF ensemble guidance points to a largely dry day with variable cloud and light winds across southeast England, supporting maximum temperatures near 22–24°C in central London. Model consensus favors modest warming from a building southerly flow and clearer spells, though differences in predicted cloud cover and boundary-layer mixing create tight clustering around 22–23°C outcomes. These values sit slightly above the June climatological average of roughly 19–20°C, reflecting the current transition from cooler early-month conditions. Traders are weighting official guidance and urban station biases, with resolution hinging on the precise peak reading at representative sites such as Heathrow or St James’s Park.
