Our dewpoint here has now been at least 78 every day since July 8, and 77 every day since June 10. Which is consecutive day runs of 21 and 49 days respectively. It's usually the highest around 9 am, which is why I never go out at that time.
Our lowest overnight temperature during July was 75.
Now that's a lot of high dew points! The highest I've seen this summer was 78 I think, and usually it's been 68-75, lately closer to 75. And that's bad enough!
Memphis 45 minutes ago had a heat index of 80F and temps of 96F. Now the heat index is 79F and the temp is almost 98F. Is it common for the heat index to go down even as the temps continue to climb?
The heat index there is currently 117F!
Have I mentioned how relieved I am not to be living there anymore?
Apparently just the thought of such miserable temperatures affected my brain.
I meant to say that the dew point went down to 79F from 80F while the temps and the heat index were still climbing. I wanted to know if that was unusual because I figured the dew point would go up along with the temperature.
Still trying to figure out how that works.
The dewpoint never really gets very high here in Perth, except for during humid spells during summer.
I've looked at some of Perth's "humid spells"
Their dewpoints can reach 15 C (59 F) 10 miles inland, and 18 C (65-66 F) by the beach.
I imagine many humidity-hating residents of eastern North America would kill for having highest annual dewpoints as low as 59-66 F.

Yes, the low humidity is helped by frequent westerly and southwesterly wind directions. It's funny, though, those cloudy 35C days FEEL really muggy and humid even when humidity is below 30% and the dewpoint probably no higher than 20C .

It's probably all relative to what you experienced recently...
After winter, our first dewpoints at 15 C feel remarkably humid.
In the height of summer, any dewpoint under 16 C feels quite dry now.
Though it seems that Perth's max dewpoints are the same in any month of the year.
Our dewpoint is forecast to plummet to a frigid 65 this afternoon, with humidities reaching a nose-bleed level of 38%. But then tomorrow, back to the normal mid-70 dewpoints. It was 77 this morning, and within a range of 73-77 yesterday.
Since June 5, our dewpoint has fallen below 70 only once for a three-hour period on June 20, when it reached as low as 64.
Dew point went down to 49°F yesterday, lowest since early July. In early July, our dew point went down to the mid 40s with the air temperature in the mid 90s. It made me rather thirsty.

38% humidity can make your nose bleed?
If so I can see why you prefer living on the Gulf Coast.
For my skin to start to be agitated by dryness,
the humidity probably has to be at least below 20% when it's not cold outside. (affects dewpoint)
I dislike dewpoints under 20 F (-7 C)
and I think I find dewpoints below -10 F (-23 C) annoying.
