Cities at the same latitude as Haapajärvi

What is latitude?

Latitude is an angular measurement that indicates how far north or south a location is from the Earth's Equator. It ranges from 0° at the Equator to 90°N at the North Pole and 90°S at the South Pole. Lines of constant latitude are called parallels because they run parallel to the Equator and to each other.

Cities located on the same parallel share identical astronomical conditions: the same length of day on any given date, the same position of the sun at noon, and the same angle of sunlight. This often means similar climate zones — though altitude, proximity to the ocean, and prevailing winds create significant differences in practice.

How does this tool work?

This tool uses a database of over 70,000 populated places from GeoNames. When you enter a city, it looks up its geographic coordinates and then finds all cities within ±0.5° of the same latitude — a band roughly 110 km wide. Results are sorted by population so the most significant cities appear first.

The interactive map is powered by Leaflet with OpenStreetMap tiles. A red line highlights the target latitude across the globe.

Surprising latitude facts

• London (51.5°N) is at the same latitude as Calgary, Kiev, and the southern tip of Alaska — yet has a much milder climate thanks to the Gulf Stream.
• Rome (41.9°N) shares its parallel with Chicago, Madrid, and Beijing.
• Sydney (33.9°S) is at the same southern latitude as Cape Town, Buenos Aires, and Perth.
