How we score this
Each month combines weather, crowds, natural-disaster risk, hotel cost and flight cost into one rating for London. Higher scores are better for typical leisure travellers.
Flight and hotel prices are not in this refresh yet — those factors are left out of the mix until the next Amadeus update.
