Planes overhead in EC1M

Islington, Camden and City of London, London. All 168 of its postcodes measured, January to August 2026.

From Heathrow

Planes land and take off into the wind, so the weather decides which way Heathrow flies, and that decides how many pass over EC1M. Across its postcodes, January to August 2026:

On a day it flies west (56% of days): up to 18 a day; of its 168 postcodes, 168 at 10 to 99
On a day it flies both ways (15% of days): up to 13 a day; of its 168 postcodes, 167 at 10 to 99, 1 under 10
On a day it flies east (29% of days): up to 2 a day; of its 168 postcodes, 168 under 10

The table counts the postcodes of each sector by how many planes pass over them a day: 100 or more, 10 to 99, or under 10.

What counts as overhead

Overhead means more than halfway up the sky (48.5 degrees or more) and below 7,000 ft, the CAA's definition of an overflight (CAP 1498). A day counts as one way when 80% of its flights used that way.
