Recent Met Office guidance indicates a daytime maximum near 17°C across London on June 11 under mostly cloudy skies with moderate southwesterly winds and possible showers. This aligns with the early-June pattern of changeable conditions following May’s record warmth and supports the market’s clustering around 16–17°C outcomes. Model consensus shows limited potential for significant warming absent high-pressure buildup or southerly flow, keeping probabilities for 18°C or higher modest while cooler readings remain possible if cloud persists. Updated short-range forecasts and official station readings will determine final resolution against historical June averages near 20°C.
