Nothing like La Nina to ruin our already short and cold summers. Hope the ***** fades away and BRING NACK EL NINO !!!
I were referring to relative humidity

Doesn't El Nino deliver more cold and wet westerlies to Victoria?

well, 95-100% RELATIVE humidity at 31C results in a dewpoint of a good 30C.....

You made it sound like the humidity was 95% at the same time the temperature was 31C. That never happens in Brisbane.

Actually I was talking in terms of body comfort - i.e - humidity relative to my body that is, not the air temperature or dewpoints. I judge humidity by how many sweat beads I produce in minutes, or even seconds, as well as finding it hard to cool down and Brisbane certainly takes the cake.

The past summer was the first one I experienced here and only a handful of days were notably humid. Around the 9th Jan it was pretty bad with a high of 37C to go with dew points in the mid 20s.

I recall him having three fans going 24/7 inside his apartment and also outside as there was very little wind. Also bear in mind you came here during an exceptionally strong wet and cloudy La Nina period. Brisbane is much more humid than Perth, there simply is no comparing those two cities.
Wouldn't you almost die if the dew points were that high? or at least have a heat stroke.

That is indeed a very accurate measurement

Dew point is a better gauge of your body's comfort in this case, and I'd advise you to use that instead of abusing a meteorological term. If you don't want to use any terminology like dew points or relative humidity perhaps you could just say "humid" or "very humid" or "muggy" instead of confusing the rest of us.

Since I started taking notice of dew points vs humidity I agree with you completely. Days here with 90's and dew points in the upper 50's to low 60's is much more tolerable than a day like last Saturday with dew points in the low 70's. It was brutal and the sweat poured off of me. Dew point is much more telling about how uncomfortable a temp feels imo.


From USA Today Weather:

Q: Is dew point or relative humidity a better indication of how humid the air feels? My guess is it's relative humidity. Also is there much variation between the dew point temperature from day to day?


A: Dew point is by far the better measurement of how humid the air feels.
This is the case because dew point is a measurement of how much humidity is in the air, no ifs, ands or buts about it. Relative humidity tells you how much humidity is in the air compared with how much can be in the air at the temperature the air happens to be when you measure it. This means that the relative humidity goes down as the temperature goes up even though the amount of water vapor in the air (humidity) remains the same.

He is just repeating the regular fallacious statements made about very high relative humidities accompanying 30C+ temperatures - I've been hearing them for decades. Accoridng to all such statements, much of the planet is like the Gulf.
