Night sky over London
The page stands in London (51.5° N, 0.1° W) and looks up at tonight's sky over it: by day its clock starts at London's dusk, so the Moon, the planets and the bright stars are where they will be once it's dark there, with the satellites in sunlight crossing between them.
The list below says tonight over London in words, worked out as the page is served: sunset and when it gets dark on London's clock (Europe/London), the Moon's phase and when it's up, and for each planet when it rises or sets, how high it climbs and where to face, with the next meteor shower.

How to read it
London is at 51.5° north, far enough that from late May to late July the Sun never gets 18° down: the sky never gets fully dark, though it gets dark enough for planets. In winter the nights are long, sixteen hours from sunset to sunrise in December, and the planets that ride high in the winter sky stand well above the rooftops.
Light pollution leaves central London only the brightest stars. The Royal Observatory in Greenwich, home of the meridian, runs evening observing sessions; to the south, the South Downs National Park is an International Dark Sky Reserve, under two hours by train, where the Milky Way shows on a clear moonless night.
Questions
When are London’s night skies clearest?
In spells of high pressure, more often in spring than in the cloudier late autumn and early winter. The weather turns fast, so it pays to check the planets’ times in the list above and step out the first clear evening they come with.
Where can I stargaze in London?
Hilltops and open ground with a wide view: Primrose Hill, Parliament Hill on Hampstead Heath, and Greenwich Park around the Royal Observatory. Planets and the Moon are bright enough to see from any of them despite the city’s glow.
Why doesn’t it get dark in London in June?
At midsummer the Sun sets far to the northwest and only skims about 15° below London’s horizon at midnight, so the northern sky keeps a glow all night. The list above says “only twilight” when it doesn’t get properly dark.
