Answer:
Latitude. It depends on how close or how far it is to the equator. This is the most important, and it is based on the concentration of sunlight and the area that it affects.
Ocean currents. Certain ocean currents have different temperatures. Warm ocean currents warm the air above it, which warms the coast. Cold ocean currents cool the air above it, which cools the coast. This helps keep the coast at a consistent temperature.
Wind and air masses. Heated ground causes air to rise which results in lower air pressure. As it rises it cools and descends to the ground resulting in high air pressure. This cycle repeats, creating wind. These air masses absorb the climate of the air below it.
Elevation. The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool.
Relief. The differences in the elevation inland. As air is forced to rise over a piece of land (e.g., a mountain) the temperature decreases and condensation increases. As it condensates water droplets get bigger and heavier and are forced to fall. Once the air mass goes over the mountain the temperature and evaporation increases but condensation decreases, resulting in a halt in precipitation and rain shadows.
