North London is the northern part of London, England. It is an imprecise description and the area it covers is defined differently for a range of purposes. Common to these definitions is that it includes districts north of the River Thames and is used in comparison with south London. However, it is also often used in comparisons with central London, east London and west London.
The River Thames divides Greater London into two parts. The northern part includes most of the historic central areas including the City, the East End and the West End; and the majority of the London Underground network.
This area is made up of the City of London and the London boroughs of Barking and Dagenham, Barnet, Brent, Camden, Ealing, Enfield, Hackney, Hammersmith and Fulham, Haringey, Harrow, Havering, Hillingdon, Hounslow, Islington, Kensington and Chelsea, Newham, Redbridge, Tower Hamlets, Waltham Forest, and Westminster. This definition is used by the Boundary Commission for England. The London Borough of Richmond upon Thames includes sections on both sides of the River Thames. The boundary commission class the entire district as part of South London.
In 1965 Camden, Hackney, Hammersmith and Fulham, Islington, Kensington and Chelsea, Tower Hamlets and Westminster were designated Inner London boroughs and Barking and Dagenham, Barnet, Brent, Ealing, Enfield, Haringey, Harrow, Havering, Hillingdon, Hounslow, Newham, Redbridge and Waltham Forest were designated Outer London boroughs.
For the purposes of the London Plan, there has been a north London subregion in operation since 2004, originally consisting of Barnet, Enfield, Haringey and Waltham Forest. In 2001 this area had a population of 1,042,000. This definition is used by organisations such as Connexions. In 2008 it was amended to consists of Barnet, Camden, Enfield, Hackney, Haringey, Islington and Westminster. In 2011 it was amended again to consist Barnet, Enfield and Haringay.

North London has, like other parts of London and the UK in general, a temperate maritime climate according to the Köppen climate classification system. Four Met Office weather stations currently collect climate data for London north of the river: Hampstead, Heathrow, Northolt and St James's Park. Long term climate observations dating back to 1910 are available for Hampstead, which also the most elevated Weather Station in the London area, at 137m. This both hilltop and urban position means severe frosts are rare.
As one might expect, temperatures increase towards the Thames, firstly because of the urban warming effect of the surrounding area, but secondly due to altitude decreasing towards the river, meaning some of the hillier northern margins of North London are often a degree or so cooler than those areas adjacent to the Thames. Occasionally snow can be seen to lie towards the Chilterns while central London is snow-free.
The average coldest night should fall to −5.6 °C (21.9 °F). On average 35.8 nights will report an air frost, some 119 days of the year will register at least 1mm of precipitation, and on 7.4 days a cover of snow will be observed. All annual averages refer to the observation period 1971–2000.
