London January — Big Ben rising through morning fog on a cold grey winter day

January

#11 of 12 months

Strong option

Empty museums, cheapest hotels — but barely 2 hours of daylight make this the toughest trade-off.

  • ↑The British Museum and National Gallery at their emptiest — no timed slots, no queues, proper unhurried visits
  • ↑Central London hotel rates at annual lows — 4-star hotels at prices that would be budget in August
London May — sunlight filtering through tall trees in Hyde Park on a warm spring afternoon

January trade-offs

  • ↓Only 1.8 hours of usable sunshine daily — the city is dark before 4pm and grey most of the day
  • ↓Cold (3°C overnight) and persistently damp; the famous London drizzle is at its most relentless
  • ↓Hyde Park and the Royal Parks are stark and leafless — no outdoor London to speak of

May trade-offs

  • ↓Prices climbing toward summer — a week at a 3-star central hotel costs noticeably more than March
  • ↓Chelsea Flower Show week sees south-west London traffic disruption and accommodation pressure
  • ↓Half-term (late May bank holiday) briefly crowding family attractions across the city
