London · Month comparison

March vs May

May ranks #1 overall vs March at #6. Chelsea Flower Show, warm parks, 18°C — London at its most seductive before summer prices arrive.

March

#6 of 12 months

Strong option

Spring stirs — daffodils in Hyde Park, daylight returning, and prices still well below peak.

  • Daffodils blanket Hyde Park and St James's Park by mid-March — London's first real colour after winter
  • Four hours of sunshine daily marks a genuine psychological shift; outdoor walks become viable again
London May — sunlight filtering through tall trees in Hyde Park on a warm spring afternoon

May

#1 of 12 months

Best match

March trade-offs

  • Easter can fall in March (check the year) — triggering a sudden crowd and price spike
  • Still cool and changeable; a warm day in mid-March can be followed by a cold snap within 48 hours
  • Major spring events (Chelsea Flower Show, Trooping the Colour) are still months away

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
