Dew is a natural form of water, formed as water vapor condenses. Dew, like the glistening drops on this grassy field in Anaconda, Montana, forms as water near the surface of the ground is cooled to its dew point, the temperature at which water vapor condenses. The dew point varies by area and even time of day.

What causes dew to form on grass overnight?
When the sky is clear or mostly clear overnight, the ground cools, and the warm air radiates away from the ground, up toward the sky. If the ground cools enough, dew then forms on the grass. When it's cloudy overnight, the ground retains more of its heat, and not as much heat is radiated up to the sky.
What does it mean when the grass is wet in the morning?
Dew is moisture that forms because of condensation. Condensation occurs when water vapor — the gas form of water — turns into water in its liquid form. At this time of year, dew is just as likely as rain to be the reason for wet grass in the morning, but whether it forms at all is related to the weather overnight.
Is dew appearing on grass caused by heat?
Those tiny droplets you see clinging to the blades of grass are called "dew." Dew is liquid water droplets that form on grass, spider webs, and other things in the early morning or late evening. Dew only forms under certain conditions. If a warm, clear day is followed by a cool, clear evening, dew will likely form.
Where Does Dew Come From?
Does morning dew help grass?
Moisture from morning dew keeps the seed bed moist and the less intense sun rays slow the rate of evaporation. The soil temperatures are still warm and the cool rains make it the perfect time to create that beautiful lawn that your neighbors will envy as they look over your fence.
Does dew provide moisture for grass?
High levels of dew in grasslands could provide the moisture needed for different types of seeds to germinate, perhaps even creating conditions that support the transition from grasslands to forests.
How can I reduce the dew on my lawn?
Condensation And It'S Forms | Dew, Fog, Frost And Mist | Video For Kids
What does dew on the grass mean?
With dew on the grass it usually means the sky is clear. During the day, the clear skies will continue and thus it will be a sunny day with no rain. We should assume that "rain will never come to pass" means for the daylight hours after the dew forms.
Does morning dew activate fertilizer?
Fog and dew that form in the evening and early morning provide enough moisture to combine with the salt in the fertilizer, allowing your grass to absorb it through its blades.
Why The Dew Point Matters Much More Than Humidity
Do I need to water grass if there is dew?
Morning dew can provide lots of benefits to outdoor plants. However, it's not enough to water your grass. As the water droplets condensate on the leaves of your plants and flowers, your plants can benefit from the extra hydration.
Why is the ground wet when it hasn't rained?
Vrydaghs said this is called “sweating,” and is caused by hydrostatic pressure pushing water and moisture through the concrete from below the surface. The more likely cause is that the concrete is colder than the air, causing condensation, making it appear wet, Vrydaghs said.
