There is often confusion between weather and climate. Weather is the condition of the atmosphere at a particular place over a short period of time. For example, on a particular day in Trinidad, the weather is warm in the afternoon. But later in the day, when there are clouds blocking Sun's rays, the weather would become cooler. Climate refers to the weather pattern of a place over a long period, maybe 30 years or more, ''long enough to yield meaningful averages'' .
