The length of time you should wait after it rains before mowing your lawn can depend on various factors, such as the type of grass, the rain’s intensity, and the soil’s condition. In general, it’s best to wait until the grass is dry before mowing to avoid causing damage to your lawn and the mower.
For most lawns, you are waiting at least 24 to 48 hours after heavy rain is recommended. This allows the soil to dry out and prevents the grass from being excessively wet, which can lead to clumping and uneven cuts. If the rain is light or the soil is well-draining, you may be able to mow sooner than 24 hours.
It’s also important to note that mowing wet grass can be dangerous as it can increase the risk of slipping and falling. Wet grass can also clog the mower deck and cause it to malfunction, leading to costly repairs. Therefore, waiting until the grass is dry before mowing is generally best.
How Long After It Rains Can You Mow? – The Great Example
Mowing can be a great way to clear your lawn of any excess water , but it’s important to wait a little bit after it rains before you do so.
If there is no more than 1/2 inch of rain in 24 hours then it takes about 1 hour to dry enough for safe mowing. If there is 1 inch or more of rain, it takes about 2 hours for the grass to dry enough for safe mowing. If there are more than 2 inches of rain in 24 hours, then it takes about 3 hours for your lawn to dry enough for safe mowing. If there are more than 3 inches of rain in 24 hours then it takes about 4 hours for your lawn to dry enough for safe mowing.

Will Mowing Wet Grass Ruin Lawn Mower?
Mowing wet grass can damage your lawn mower, especially if the grass is excessively wet or the mower is not equipped to handle wet conditions. Wet grass can cause clumps to form, which can clog the mower deck and damage the blades. The clumps of wet grass can accumulate under the mower deck and cause rusting or corrosion over time, leading to expensive repairs or premature replacement.
In addition to damaging the mower, mowing wet grass can also be dangerous, increasing the risk of slipping and falling on wet grass. Therefore, waiting until the grass is dry before mowing is generally recommended to avoid damaging your lawn mower and to ensure a safe mowing experience.
In addition, mowing has other functions, such as reducing weed growth in turf through trimming and thinning out thickets of unwanted weeds before they set seed.
Helpful Tips For Mowing Grass After Rain
Here are some helpful tips for mowing grass after rain:
- Wait until the grass is dry: As mentioned earlier, it’s best to wait until the grass is dry before mowing to prevent clumping, clogging, and damage to your lawn mower.
- Adjust the mowing height: Set your mower blades to the appropriate height for your grass type and mow higher than you normally would. This will help prevent scalping and allow the grass to recover more quickly from the stress of being mowed when it’s wet.
- Use a sharp blade: A sharp mower blade is essential for a clean and efficient cut, especially when mowing wet grass. A dull blade can tear the grass and cause more stress, which can lead to disease and other issues.
- Mow in a different pattern: If you usually mow in the same direction, consider changing the pattern to avoid compacting the wet soil in the same areas. This can also help prevent clumping and allow the grass to stand up more easily.
- Clean the mower deck frequently: Wet grass can stick to the mower deck and build up quickly, so it’s important to stop and clean the deck frequently during mowing. This will help prevent clumping and clogging, and reduce the risk of rust and corrosion.
Best Time For Mowing After Rain
Mowing can be done pretty quickly after rain, but a few things to keep in mind. Here are the best time frames for mowing after rain:
- Within an hour of the heaviest rain: grass is saturated and will need more time to dry out.
- Two hours after the heaviest rain: grass is starting to hydrate and will begin to look green again
- Four hours after the heaviest rain: grass is mostly hydrated and should be looking good.
- If you want a clean-cut and don’t want your mower’s blades clogged with grass.
- If you have a riding mower with a bagger and don’t want debris caught in the blades or chute.
- If you have a mulching mower and want to keep leaves out of your yard while still damp (mulch).
Mowing in Rain is Harmful to Mower
It’s best to mow when the grass is dry. The clippings will clump together, mat down, and stick to the lawnmower deck if you mow wet grass. This can cause excessive stress on your lawnmower and reduce its ability to cut the grass cleanly.
Other Harmful Aspects
It’s important not to cut wet grass because it can result in a lawn with brown patches that cut off the blades at different heights. You may also see some weeds growing through this patchy area since they don’t need as much sunlight as normal lawns do.
Should Not Cut Grass When It’s Wet?
Cutting wet lawns can cause damage to your lawnmower, as well as your lawn.
Here are some reasons why:
- The clippings will stick to each other and form clumps. This makes them heavier and harder to remove from the lawn, which means more work for you and less time for them to break down into nutrients for the soil. Also, if these clumps are left on the ground they may cause disease problems in your grass.
- It’s more difficult for the mower blades to cut through wet grass than dry grass because the water makes it harder for them to slice through their blades of grass to get them off at their base so they can be shredded up into smaller pieces by their cutting mechanism. This results in increased strain on your machine, which can lead to premature wear on parts or even worse damage if it were allowed to continue operating under these conditions for an extended period of time without being serviced as needed.
- When cutting wet grass, you could damage the blades on your mower if they hit rocks or sticks in the ground or if they become too dull from constantly running into wet clumps of grass.
- If you use an electric mower and cut wet grass, it can cause electrical shorts in wiring due to corrosion that occurs when water gets into electrical connections.
- It can damage your mower’s engine and belt.
- It can cause soil erosion and runoff, which can pollute waterways and damage plants.
- It’s especially true if you have clay soil since it will stick to the blades of your mower and build up on the deck.
- The water in the grass can wash away the fertilizer before it has time to work its magic.
- If the weather has been warm enough for insects like grubs or chinch bugs to hatch in wet conditions, mowing wet grass could damage your blade and spread disease spores into your home or garage where they could infect other parts of your yard or garden later on. Letting some time pass between cutting wet grass and mowing again will also help prevent the disease from spreading throughout your lawn as well as reduce it.
What happens if you Mow Your Lawn when it’s wet?
- Clumping: Wet grass can clump together and stick to the underside of the mower deck, causing the mower to clog and stop working correctly.
- Uneven cut: Wet grass tends to bend over and flatten out, making it difficult for the mower blades to cut evenly. This can lead to a patchy or uneven-looking lawn.
- Scalping: When mowing wet grass, the mower’s weight can cause the wheels to sink into the soft soil, leading to scalping or cutting the grass too short. This can cause stress to the grass and make it more susceptible to disease and other issues.
- Damage to the lawn: Mowing wet grass can cause damage to the grass blades, making them more prone to disease and insect infestations. Wet soil can also become compacted under the mower’s weight, making it harder for the grass roots to grow and absorb nutrients and water.
- Damage to the mower: Wet grass can accumulate under the mower deck and cause rusting or corrosion over time, leading to expensive repairs or even premature replacement.
