Recent Met Office and ensemble forecasts highlight mostly dry conditions across southern England through late October, with only isolated light rain expected in the coming weeks, supporting the market's 52% implied probability on totals below 35 mm. Early October has delivered just over 9 mm so far, well below the long-term average of roughly 65–75 mm for the full month. High-pressure influence and southwesterly flow have suppressed widespread rainfall, though model spread increases beyond 10–14 days and could allow for heavier episodes if Atlantic systems strengthen. Traders appear to weigh the current pattern and short-range guidance most heavily ahead of the next major forecast updates.
