Cloudy days occur when the sky is covered with clouds, blocking sunlight from reaching the ground. These clouds can vary in thickness and type, affecting the amount of light and warmth that penetrates. Common types of clouds include cumulus, stratus, and nimbus, each contributing to different weather conditions. On cloudy days, temperatures can feel cooler, and there is often a higher chance of precipitation, such as rain or snow. The presence of clouds can also create a soft, diffused light, which can be pleasant for outdoor activities. Many people find cloudy days calming and enjoy the cozy atmosphere they create.
