What Temperature Is Too Hot to Mow the Lawn and How It Affects Your Grass: A Detailed Guide
What Temperature Is Too Hot to Mow the Lawn?
The temperature at which it is too hot to mow the lawn depends on the type of grass being mowed.
Generally, it is recommended to avoid mowing a new lawn when the temperature is above 70˚F to prevent long-term damage.
Mowing in temperatures above 90°F can further damage grass that is already stressed due to heat and potential dehydration.
It is best to wait for temperatures to reduce for optimal growth and to minimize damage by mowing during cooler temperatures, raising the height of the blades, and watering the grass thoroughly afterwards.
Key Points:
- Temperature for mowing depends on the type of grass
- It is not recommended to mow a new lawn above 70°F to prevent long-term damage
- Mowing above 90°F can damage stressed and dehydrated grass
- Wait for temperatures to reduce for optimal growth and minimize damage
- Raise the height of the blades and water the grass thoroughly after mowing
- Mowing during cooler temperatures is best for grass health and growth
Did You Know?
1. If temperatures exceed 90°F (32°C), it is considered too hot to mow the lawn as the grass can become stressed and prone to damage.
2. Mowing the lawn during the hottest parts of the day can cause the grass to lose more moisture, leading to a parched and dried-out appearance.
3. When mowing during very hot temperatures, the friction of the lawn mower’s blades can create a lot of heat, which can be dangerous for both the grass and the mower itself.
4. Extremely hot weather can make the soil dry and hard, making it challenging to push the lawn mower and resulting in a less even cut.
5. Weather conditions, such as high humidity and intense sunlight, can make mowing the lawn in extreme heat even more unbearable for the person doing the task, increasing the risk of dehydration and heat-related illnesses.
Mowing A New Lawn In Hot Weather: Temperature Guidelines
Mowing a lawn in hot weather can result in damage to the grass. It is crucial to be aware of the temperature limits for mowing, particularly for newly established lawns. To promote healthy growth and prevent long-term harm, it is recommended to avoid mowing a new lawn when the temperature is above 70˚F (21˚C).
New lawns are fragile and highly vulnerable to heat stress, leading to stunted growth, wilting, and potential death of the grass.
- Avoid mowing a new lawn when the temperature exceeds 70˚F (21˚C) to prevent damage.
- Newly established lawns are particularly susceptible to heat stress.
- Heat stress can result in stunted growth, wilting, and grass death.
Note: Mowing at the wrong temperature can harm newly established lawns. To prevent damage and promote healthy growth, it is essential to avoid mowing when temperatures exceed 70˚F (21˚C).
Avoid Scalping The Lawn: Effects Of Mowing In Hot Weather
Mowing the lawn during hot weather can have negative effects, especially when the blades are set too low. This can result in a harmful practice called scalping, where the grass is cut too short, leading to bare patches and browning. Scalping is particularly damaging in hot weather because it exposes the soil to direct sunlight and excessive heat, further stressing the grass. As a result, this creates an ideal environment for weed growth as the weakened grass is unable to compete effectively.
To summarize:
- Mowing the lawn during hot weather with low blade settings can cause scalping.
- Scalping leads to bare patches, browning, and exposes the soil to sun and heat.
- Hot weather increases the stress on the grass, making it more susceptible to weed growth.
Dull Blades And Dry Lawns: Potential Damage To Grass
Using a mower with dull blades on a dry lawn in hot weather can exacerbate the potential damage to the grass. Dull blades tear at the grass instead of making clean cuts, causing additional stress and trauma to the already struggling grass. Moreover, the torn grass blades are more susceptible to disease and fungal infections. To maintain a healthy lawn, it is essential to regularly sharpen the blades of your mower and ensure they are in optimal condition before mowing, especially during hot weather.
Restoring Heat-Stressed Turf: Watering And Maintenance Tips
When your lawn experiences heat stress due to mowing in hot weather, it is crucial to take immediate remedial action to restore its health and vigor. The key to revitalizing heat-stressed turf lies in effective watering and maintenance. Make sure to water your lawn thoroughly after mowing to replenish moisture levels and provide relief to the grass. Additionally, proper maintenance practices, such as regular fertilization, aeration, and overseeding, will help promote new growth and strength.
Minimizing Damage: Mowing Techniques For Hot Weather
To minimize damage when mowing in hot weather, it is essential to employ specific techniques that promote the health and resilience of your lawn. Mowing during cooler temperatures, such as early morning or late evening, reduces the stress on the grass. This allows the grass to recover more effectively, as it is less exposed to intense heat. Additionally, adjusting the height of the mower’s blades to a higher setting will leave the grass longer, providing shade for the soil and reducing moisture loss. Finally, always remember to water your lawn thoroughly after mowing to help it recover from the stress of mowing in hot weather.
“Understanding the temperature thresholds for mowing the lawn is crucial to maintaining a healthy and vibrant lawn.”
- Mowing a new lawn in hot weather above 70˚F can cause severe long-term damage.
- Scalping the lawn, using dull blades, and mowing in excessive heat can further stress and harm the grass, leaving it vulnerable to disease and weed growth.
However, by following proper watering techniques, practicing regular maintenance, and employing appropriate mowing techniques, you can minimize the damage caused by mowing in hot weather and ensure the continued health and beauty of your lawn.
- Mow during cooler temperatures
- Adjust mower blade height higher for longer grass
- Water lawn thoroughly after mowing

Frequently Asked Questions
What temperature is best for cutting grass?
The optimal temperature for cutting grass is between 50 to 80 degrees Fahrenheit. Mowing in this temperature range ensures that the grass is not stressed and can recover quickly. Following the one-third rule is also important, as it prevents excessive stress on the grass and promotes healthy growth. By not cutting off more than one-third of the grass’ current height in a single mowing session, the grass can maintain its integrity and continue to grow effectively.
What temperature damages grass?
Grass can be damaged when exposed to temperature extremes outside of its optimal range. Excessive heat, reaching or exceeding 110 degrees F, can cause severe stress to the grass, leading to wilting, browning, and decreased growth. On the other hand, consistently cold temperatures below 55 degrees F can also harm grass, particularly warm-season varieties. In such conditions, the grass’s roots cease to grow, impeding its ability to efficiently absorb nutrients and moisture, ultimately weakening its ability to endure extreme temperatures.
Can you cut grass in the sun?
The optimal time to cut grass is during mid-morning when the sun is not too harsh and the temperatures are not at their peak. Mowing grass during the morning allows it to dry and heal properly before dusk arrives. It is important to avoid mowing in the early morning or early afternoon as it may cause damage or burn the grass due to extreme temperatures. However, if mid-morning is not feasible, it is best to choose a time when the sun is not overly intense to ensure the health and well-being of your lawn.
How do you keep cool when mowing?
To beat the heat while mowing, staying in the shade during breaks and avoiding eating lunch in a hot truck can make a significant difference. If a cool indoor spot is not available, finding a shady area to relax can provide some relief. Additionally, considering the purchase of a few misting bucket fans can take the cooling experience to the next level by providing a refreshing mist of water while you work.
