The time it takes for wet grass to dry can vary depending on several factors such as the temperature, humidity, sunlight, air movement, and the thickness and density of the grass. On average, it can take anywhere from a couple of hours to a full day for wet grass to dry completely.
In sunny and warm conditions with low humidity and a gentle breeze, the drying process may be faster. However, in cooler or humid conditions, it may take longer for the grass to dry. It's also worth noting that longer and denser grass can retain moisture more effectively, leading to a longer drying time.
