# London City Guide – Complete Maps and Geographic Atlas 2026

When you consult a **London map**, you’re looking at the vibrant heart of the United Kingdom—a global metropolis where ancient history collides with cutting-edge culture. London is the capital and largest city of both England and the UK, with a population of 9.1 million residents as of 2024. Its wider metropolitan area is the largest in Western Europe, home to 15.1 million people. This **London guide** will navigate you through its remarkable **London geography**, essential **London travel** information, and the unmissable sights that make millions **visit London** each year. Situated on the River Thames in southeast England, London has been a major settlement for nearly 2,000 years, evolving from a Roman outpost to a world-leading financial and cultural capital.

## Detailed Geographic Location & Landscape

London’s **geography** is defined by the River Thames, which slices through the city from west to east. The city sits at the head of a 50-mile (80 km) tidal estuary that opens into the North Sea. Its ancient core, the **City of London**, was founded by the Romans as *Londinium* around 50 AD and still retains its medieval boundaries. To its west lies the **City of Westminster**, the historic seat of government and monarchy.

The modern administrative area, **Greater London**, was established in 1965 and encompasses 32 London boroughs plus the City of London, governed by the Greater London Authority. This sprawl historically crossed the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire. The terrain is generally flat, with gentle hills in the north (e.g., Hampstead Heath) and south. Key geographic zones include:
* **The Thames Valley:** The linear corridor along the river, hosting most major landmarks.
* **The London Basin:** The low-lying clay landscape surrounding the valley.
* **Metropolitan Green Belt:** Protected green space encircling the urban area, limiting sprawl.

Understanding this layout on a **London map** is crucial for navigating its diverse neighborhoods, from the financial skyscrapers of the City to the village-like feels of areas like Richmond or Dulwich.

## Climate: What to Expect Year-Round

London experiences a **temperate maritime climate**, characterized by mild temperatures, frequent cloud cover, and rainfall distributed throughout the year. Expect cool winters (average highs 8°C/46°F) and mild summers (average highs 23°C/73°F). Snow is rare but possible. Rainfall averages about 600mm annually, with light drizzle common. The city can occasionally experience heatwaves (temperatures exceeding 30°C/86°F) or, rarely, cold snaps. The best **London travel** months are late spring (May-June) and early autumn (September-October) for pleasant weather and fewer crowds. Always carry a light jacket or umbrella—it’s famously unpredictable.
