An 80% chance of rain does not necessarily mean it will rain all day. This percentage, known as the probability of precipitation, indicates there is an 80% likelihood that rain will occur at any given point in the forecast area. It could range from light, brief showers to longer periods of rain, but it doesn't guarantee continuous rainfall throughout the entire day. Weather conditions can vary significantly, so it's wise to prepare for rain without expecting constant downpour.
