Wikipedia says it’s “the period of twilight each morning and evening when the sun is a significant distance below the horizon and the residual, indirect sunlight takes on a predominantly blue hue” .
Neither full daylight nor complete darkness, these 40 minutes are pure bliss.
Chase the blue, seize this hour! Plenty in London.
Blue Hour @ Putney Bridge in SW London
Winter sunset @ Connaught Waters
Try this on a sunny Sunday afternoon: walk on the south bank from Putney Bridge to Hammersmith Bridge. Start around 4 pm (in summer, 1 pm in winter) to make the most of the sun. And sunsets. At Hammersmith Bridge cross and stop at a river pub, get some more sun while hugging some zingy blonde ale. When appropriate to leave, bid goodbye and walk on the north bank back to Putney. The sun sets on your right side, and will warm your back. I’m not gonna tell you much about what you’ll see along this rather short but mighty walk. But yes, it’s a story with gardens, forests, new developments, old pubs, palaces, churches, swans, wild ducks, boats and strolling humans. Joy! I mean, enjoy!

February sunset with New Moon, Barbican towers, rooftops and tiny plane
One Tree Hill sunset
Grab take away food and head for the river. Wobble in the orange sun, but leave before it hits the ground. Resist temptation and walk past Trafalgar Tavern into the park. Climb One Tree Hill: venerable chestnut surrounded by significantly less tourists than the vis-à-vis Royal Observatory hill. Better vista too. Soak yourself in more sunset, then walk into the twilight across Blackheath Common. Join a local pub for sticky pud and idle talk under the starry sky.
