I assumed that, but your numbers were off. When your average person thinks of humidity, they think of a 95 degree summer day. In reality, a fall day with dew on the grass that feels more comfortable because of the lower temperature could actually be 100% relative humidity. High humidity doesn't only occur on hot summer days.
Went down to 38%, boy is it sweltering. Glad I don’t have an outside job today. Makes me remember those days fencing out in an open field, no shade. Sit the digging iron down for lunch and can’t pick it back up. Or roofing, eff that!
I think this thread is a great way to point out how ridiculous it is when people say "Yeah its 110F, buts its a dry heat!" 110 degrees is 110 degrees. Its not the humidity that makes you feel like garbage, its the fact that its 110 DEGREES!!! The 100% humidity in other seasons no one ever mentions. But its a dry heat!!! Its one of those things people parrot throughout their lives without actually looking into it themselves. Kind of like "You cant burn pine"
Take a look a humidity forecasts. On days it isn't raining it is most humid after dusk until an hour or two after dawn. It's a trade off, work outside at 6AM @75F and 90% humidity or 11AM @ 90F and 50% humidity.
Yup In fact winter days on average are about 10% higher humidity than in the summer. So more humidity, less sunlight, lower temps. I think the question as to which season dries wood better should be pretty obvious.
Exactly! It feels humid because it’s so damm hot out but the air is much drier than we realize on most of those hot days
Rule of thumb is that the relative humidity will double for every 20 degrees that the temperature drops and cut in half for every 20 degrees that the temp goes up, given the same absolute amount of moisture in the air. (At a constant dew point). That’s why the RH typically goes way down in the afternoon and climbs back up in the evening.
If we all just went outside on hot days like today we could see the water boil out of the wood. Mystery solved LOL
Beating a dead horse, all sorts of info about drying wood all over the net. High temperatures bring the moisture to the surface and the wind takes it away.
I haven't figured out how to upload a psychrometric chart, but basically just as we all know heat always wants to equalize.....move from places of high concentration to low concentration. Humidity does the same thing. Humid weather is not good for drying out wood. Wind definitely helps, but is not the end all be all. Not PSYCHO..........psychRo......notice the R
Another day that feels humid with a relatively high dew point (68) and lower humidity than most would expect.
If you told me it wasn’t humid out yesterday, I may have punched you in the face but the data doesn’t lie.
Punched you in the face he says!!! I know exactly how you feel. We'd be up on a roof shingling in 90 degree weather and a homeowner would pull up in there AC car, offer no refreshments and say something idiotic like "It looks hot up there!" Or someone would say "I LOOOOOVVVVVEEEEE the heat, I cant get enough". Meanwhile you find out they spend all day, everyday going from AC house, to AC car, to AC store, back to AC house. One out of every 10 would actually have a job, and it was typically an office job in the you guessed it AC. If you love it so damm much how about spending 9 or 10 hours working in it.
I have been monitoring my wet and dry bulb temperatures recently as I just put 8 green cord in my shed. I have been running a 30” drum fan. I measured the air coming into and out of the stack. Quite impressive is the temperature drop and near saturation of the air coming out. My calculations tell me I need to lose 2800 lb of water or around 340 gallons to evaporate. 7/25 In 58 72 RH50 Out 58 62 rh95 7/26 In 72 87 rh44 Out 69 74 rh88 7/27 In 74 96 rh35 Out 69 79 rh60
