Which dew point ranges do you consider dry/humid?

DP over 15 but depends on temp.

>78F: Oppressive
72-77F: Muggy
65-72F: Very Humid
58-65F: Humid
48F-58F: Neutral
<48F. Dry

^^Thats about right, but i need to see it written like this: ( you Imperial Fahrenheit fuck !   )

>=27c: Oppressive
24.4-26.7c: Muggy
21.7-23.9c: Slightly Humid
16.1-20.0c: Neutral
10.6-15.6c: Dry
<=10c: very Dry

Was chatting with a mate up at Gunn Point ( 80klm north east by road from  Darwin and on a bit of a peninsular.) He has an offical BOM weather station 200m away from where he lives. his DP's are nearly always 2-3c higher than Darwin, although often max and min temps are lower. He can and does see dews about 30c and max temps 31-32c. We often discuss how bad it 'feels like'

28c - 30c = really absolutely shithouse ( even for the acclimatised )
25c - 28c = really shithouse, especially in the mornings as the sun gets hotter. We get a few 34c/27c days in the Wet Season, trust me, its shithouse !
20c - 25c = pretty well the normal, so doesn't bother locals ( too much ), but interstate visitors from down south really suffer and complain.
15c - 20c = locals all saying, "what a magic dry season day it is today ! ( Sat the 7th May was 33c/13.4c a 3.30pm, dried out all my potted plants )
10c - 15c = deep in June/July, not a cloud in the sky for months at a time, just about forgotten how bad last 'wet' was....
5c - 10c = skin flaking, chapped lips, too cold to swim in the backyard pool, gusty winds blowing to 40knots, dangerous bushfires in Aug/Sept.

That's us at 12.4*S

Here is how I categorise dew points measured, regardless of temperature. In addition, I will explain to you how my skin feels at the following dew point thresholds:
Unbearable: 27ºC (80.6ºF) and higher-I think that my skin will feel like an open sauna, fully made out of steam, and straight-up unbearable. Unbearable conditions are record breaking events in Sydney's summers.
Miserable: 24 to 27ºC (75.2-80.6ºF)- My skin will feel very clammy, and sweat will appear on the surface. It is most uncomfortable in the morning. Miserable conditions hardly ever occur in Sydney's summers.
Oppressive: 21 to 24ºC (69.8-75.2ºF)- My skin will feel rather clammy, and it even for my humidity-loving skin, the overwhelming moisture will take effect. Oppressive conditions occur for about 10% of summer.
Muggy: 18 to 21ºC (64.4-69.8ºF)- My skin will feel slightly clammy, but will not be so dry compared to Winter. Muggy conditions occur for about 30% of summer, and 10% of autumn/fall.
Acceptably Humid: 15 to 18ºC (59.0-64.4ºF)- My skin will feel slightly dry. Acceptably Humid conditions occur for about 40% of summer, 25% of autumn/fall, and 10% of spring.
Ideal: 12 to 15ºC (53.6-59.0ºF)- My skin will feel dry, but my mind will consider this range to be ideal. Ideal conditions occur for about 15% of summer, 25% of autumn/fall, and 25% of spring and 10% of winter.
Acceptably Dry: 9 to 12ºC (48.2-53.6ºF)- My skin will feel very dry, and peeling begins with scratching. Acceptably Dry conditions occur for about 5% of summer, 20% of autumn/fall, 30% of spring and 20% of winter.
Dry: 6 to 9ºC (42.8-48.2ºF)- My skin will feel severely dry, peeling begins with only minor scratching. Dry conditions occur for about 10% of autumn/fall, 20% of spring and 35% of winter.
Very Dry: 3 to 6ºC (37.4-42.8ºF)- My skin will feel extremely dry, peeling is inevitable. Very Dry conditions occur for about 5% of autumn/fall, 10% of spring, and 25% of winter.
Severely Dry: -3 to 3ºC (26.6-37.4ºF)- My skin will feel incomprehensibly dry, peeling occurs outside of "hotspots." Severely Dry conditions occur for about 5% of spring, and 10% of winter.
Extremely Dry: -9 to -3ºC (15.8-26.6ºF)- My skin will begin to peel and crack in most places. Extremely Dry conditions hardly ever occur in Sydney's winters.
Incomprehensibly Dry: -9ºC (15.8ºF) and lower- I think that my skin will crack and peel in all places, and fall off. Incomprehensibly Dry conditions are record breaking events in Sydney's winters.

In general:

>78F: Extreme

74-78F: Oppressive

68-74F: Muggy

60-68F: Humid

40-60F: Comfortable

20-40F: Dry

<20F: Very Dry

20C or above: Hell

15-20: oppressive

15-10: muggy

5-10: humid

5C or below: comfortable

A reasonable explanation of dew point tolerances
( source: Aussie Weather Watch )
"Dew point is the temperature at which dew will form, the higher that dew point the more moisture is in the air. Most people think that high relative humidity is the best way to measure how uncomfortable it is but it is misleading, dew point is the best way to understand how muggy it really is. As a rule of thumb for most people living in a temperate area their whole lives will find a dew point of 15°C or higher uncomfortable and a dew point at 21°C to be oppressive and "Tropical like". Where as someone living in Darwin without AC (AC lowers dew point so if you are in AC alot your dew point tolerance is comparable to a person in a temperate climate) will find dew points of 21°C bare able, under 20°C feels dry and 26°C or over is oppressive. Older and younger people are also effected differently too.
Here's a chart to give an idea, again this is based on someone living in a temperate region and is just an average. Individuals can have a higher or lower tolerance".
Figures from Gunn Point, 70klm north of Darwin:

<60: not humid at all
60-65: slightly noticeable
65-69: a little sticky
70-74: properly sticky
75-79: very sticky
80+: I don't think I've ever experienced this before

Keep in mind, I use "sticky" as a positive descriptor!
