1. Latitude

The closer you are to the equator, the warmer it is.

Slide 6 - Slide

2. Altitude

The higher, the colder.

3. Land or sea

Land heats up and cools down quicker than water.
Land and water influence the temperature of the air above it.

4.Onshore/

offshore wind

This factor only applies to places close to the sea.
Onshore wind moderates temperature (cool summers, mild winters), while offshore winds cause bigger temperature differences.
