Cape Town is situated near the Atlantic Ocean. The city is surrounded by mountains. The Atlantic Ocean has a moderating effect on the climate. It helps keep the temperature relatively stable. The mountains create rain shadows and affect the wind patterns.
The mountains force warm air to rise. As it rises, it cools, and the water vapor condenses. This creates clouds and precipitation. The clouds often gather over the mountains. They can bring rain to the city.
The direction of the wind also affects the weather. A south-easterly wind brings warm air from the ocean. This results in clear skies and fair weather. A north-westerly wind brings cool air from the land. This results in cloudy skies and rain.
