About this Market

Recent Met Office guidance and ensemble model runs indicate a southerly airflow drawing warmer air northward across southern England ahead of an approaching Atlantic front, supporting afternoon maxima in the 24–26 °C range for London on 29 September. Variable cloud cover and a 30–50 % chance of showers could limit surface heating and cap the peak near 25 °C, while clearer spells might allow brief excursions to 26–27 °C. Trader probabilities cluster tightly around these values because forecast uncertainty remains high within 48 hours of the event, with resolution depending on precise timing of any rain bands and the strength of insolation during the warmest hours. Updated model cycles expected later today will likely refine the most probable outcome.
