Current forecast guidance from the UK Met Office and ensemble models points to a maximum temperature of 14–15 °C in London today, with the market split nearly evenly between these outcomes because afternoon cloud cover and scattered showers will limit solar heating. A mild westerly flow is bringing Atlantic air across southern England, keeping overnight lows near 8–10 °C while daytime peaks depend on the exact timing of thicker cloud arriving from the west. Historical May averages for the region hover around 17 °C, so today’s subdued readings reflect a temporary suppression of radiative warming rather than a broader seasonal shift. Updated model runs later this morning and real-time observations from central London stations will determine whether brief sunny intervals allow a brief climb to 15 °C or cap readings at 14 °C before resolution.
