Rain season
London's rain is consistent rather than intense — rarely heavy, but reliably present throughout the year. Autumn (October–December) and winter bring the most persistent overcast and drizzle, while summer can go weeks without rain before a sudden shower. Annual totals (600mm) are lower than Rome or New York; the grey reputation comes from overcast frequency, not volume.
