We slept under wet sheets now and then in southern Oregon.

My old house here has 9+' ceilings. Actually, I imagine that both insulation and a basement make more of a difference for interior temperatures but this is a small house and I appreciate room in any direction.

It's 90° at 2pm. Humidity is 23%. I have never paid any attention to dew point. What am I missing? It's 48°

He's 8. They did both get cool bubble baths and enjoyed it last night. I actually cheated and became very neighborly with my next door neighbor who has A/C. :D She was happy to gab to someone about the birds and the garden and chickens. Rin was happy to be somewhere cool with a person who likes babies, and I was just glad Rin was glad lol

Dew Point vs. Humidity

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 anymore water in the gas form. If the air were to be cooled even more, water vapor would have to come out of the atmosphere in the liquid form, usually as fog or precipitation.

The higher the dew point rises, the greater the amount of moisture in the air. This directly effects how "comfortable" it will feel outside. Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. It would feel much more "humid" on the 80 degree day with 50% relative humidity than on the 30 degree day with a 100% relative humidity. This is because of the higher dew point.

So if you want a real judge of just how "dry" or "humid" it will feel outside, look at the dew point instead of the RH. The higher the dew point, the muggier it will feel.

General comfort levels that can be expected during the summer months:

  • less than or equal to 55: dry and comfortable
  • between 55 and 65: becoming "sticky" with muggy evenings
  • greater than or equal to 65: lots of moisture in the air, becoming oppressive

Pondering this ...

Our bodies are almost 100° and yet we are comfortable at 70° , room temperature. We are in continuous need of cooling.

If the air around us is saturated with moisture, evaporative cooling may not occur. On the other hand: If the air temperature is cold and the air is saturated with moisture, heat is being pulled away from us since moisture will do that ... kinda like leaning against cold metal.

I imagine that all that is of much more serious consideration elsewhere. Here, one is constantly in need of hydration and that must indicate the amount of cooling that takes place through the skin's surface. Then in winter, dry air can be trapped in clothing and serves as insulation.

A couple years ago.....maybe three years now? when my dh and I were out in Eugene in late June, it was really hot out there, in the 90s. They don't have AC and I thought it would be miserable, but it wasn't. Nice and dry, with a breeze blowing. Very comfortable.
Now I remember that it was 2 years.

Here in SE Missouri, it has been really pleasant the past 4 days, but the humidity is creeping back now. I think summer will come on with a vengeance now. After we get through the next week of rain. Again.

Today is will be a cool 64 but I will be heading to Sacramento where it will be hot! Will work in the "cool" of the evening on my daughter's front yard. Will be planting about 10 plants, putting cardboard down and wood chips.

i'm still giggling about "meatloafing". :) :) :)
When my dogs are unhappy they protest by tucking in all their legs and tail, and blobbing about like a meat loaf. We've since adopted the word for anyone who lies around in protest lol, even if they are not a dog and their legs are not tucked in.
