What Dew Point Is Uncomfortable?
A dew point between 55°F and 60°F is noticeably humid. It’s muggy when the dew point is above 60°F and it’s uncomfortable outside when it ticks above 65°F. Any dew point readings above 70°F are oppressive and even dangerous the kind of stickiness you experience in the tropics or during a brutal summer heat wave.
At what point is humidity uncomfortable?
At 90 degrees we feel uncomfortable at dew points of 65-69 degrees. But the RH may be only 44 – 52 percent (half the atmosphere’s capacity). Dew points above 70 degrees feel oppressive.
What is a bad dew point?
So a dew point of 60° with an air temperature of 60° is at 100% relative humidity. … Dew point below 55° = Very comfortable you don’t even notice the humidity. Dew point of 55° to 60° = Pretty comfortably but you notice a touch of humidity. Dew point of 60° to 65° = Starting to feel humid but not too bad.
What is a comfortable humidity and dew point?
The optimum combination for human comfort is a dewpoint of about 60 F and a RH of between 50 and 70% (this would put the temperature at about 75 F). The air feels dry outside when BOTH the dewpoint is below 60 F AND the RH is less than 40%.
What dew point is uncomfortable in Celsius?

Why is a high dew point uncomfortable?
Dew point is an indicator of the total amount of moisture in the air. … High dew points are uncomfortable because the air’s humidity slows the evaporation of perspiration from your body which is nature’s way of cooling you off.
What is dew point for dummies?
The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form.
What does a dew point of 70 mean?
A dew point of 70 or above is really going to weigh you down and bump up the feels like temperature significantly. Comfort Scale. Warmer air is able to sustain higher levels of water vapor. That’s why hot summer days have the potential to bring higher dew points and the most oppressive feels-like conditions.

A dew point between 55°F and 60°F is noticeably humid. It’s muggy when the dew point is above 60°F and it’s uncomfortable outside when it ticks above 65°F. Any dew point readings above 70°F are oppressive and even dangerous the kind of stickiness you experience in the tropics or during a brutal summer heat wave.
What is a good dew point to run in?
| Dew Point in °F (°C) | Performance Adjustment | Hard Running |
|---|---|---|
| 70°F (21°C) to 75°F (23°C) | 5-8% | Very difficult |
| 75°F (23°C) to 80°F (25°C) | 12-15% | Not recommended |

What is the highest dew point ever recorded?
95°F
The highest dew point ever recorded 95°F (35°C) was recorded at Dhahran Saudi Arabia on July 8 2003. With an air temperature of 108°F (42°C) the heat index was 178°F (81°C).
What is uncomfortable humidity?
While there’s no set humidity threshold above which general comfort level begins to deteriorate NOAA typically considers relative humidity (RH) levels of 50% or more and dewpoints (a more direct measure of humidity) above 65 F (18 C) to be uncomfortably high.
What is the most comfortable humidity?
between 30-50%
The ideal relative humidity for health and comfort is somewhere between 30-50% humidity according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.May 6 2019
What is a high dew point?
Let’s now look at dew point temperature: The general rule of thumb is that dew points in the 50s or lower is comfortable during the warm months. 60 to 65 and it feels sticky or humid. Dews above 65 are downright muggy and even tropical when they reach the 70s.
Does dew point affect arthritis?
One study assessed daily values for dew point precipitation and relative humidity in addition to temperature and barometric pressure. 2 It found that patients with knee arthritis experienced increased pain with every 10-degree drop in temperature. This suggests that temperature is a leading contributor to pain.
How can I lower the dew point in my house?
- An HVAC system that can cool the air to the dew point temperature without super cooling the building. …
- A humidistat and controller that senses the humidity and then activates the HVAC to dehumidify the building.
Does the dew point affect breathing?
You may not notice that the dew point is high due to the lack of muggy weather but a high dew point during cold weather can still harm your lungs. Air that’s cold and dry can irritate your airways if you have COPD. It may lead to wheezing shortness of breath or coughing.
What is the lowest dew point possible?
The dew point can drop below zero in the same manner that the temperature can. Dew point is the temperature to which air must be cooled for saturation to occur so in your example the temperature would have to fall to 6 below zero for condensation to occur.
Can temp drop below dew point?
Although the air temperature can never go lower than the dew point the dew point can drop as the temperature goes down. If the predicted temperature is 34 degrees and the dew point is 32 degrees you probably will not get frost.

What is dew point in layman’s terms?
The dew point is the temperature where water vapor condenses into liquid water. All air holds different amounts of water vapor. … The higher the dew point is the higher the level of moisture in the air at a given temperature. The dew point of humid air will be higher than the dew point of dry air.
What is more important humidity or dew point?
Viewers have asked us the fine question “When discussing humidity or comfort levels why don’t you give the relative humidity instead of the dew point?” The reason: dew point temperature is a much more consistent and reliable gauge of your comfort level than relative humidity.

For runners a dew point greater than 65° F will start to feel uncomfortable and higher than 70° F will make even an easy effort feel challenging. Although humidity and a high dew point will usually feel worse to the average runner dry hot air can also be problematic.
Does the dew point change?
No. Dewpoint will not change as the system temperature changes below the saturation point. If the system temperature is at or below the dewpoint temperature in a closed system the dew point will change because the water vapour is removed from the air.
