My area has a reasonably large diurnal range (11.6C) for a sea level location, and reasonably high rainfall (1440 mm/58 inches), although I don't think of it as a humid climate.
Days are as warm as could be expected for the climate/latitude, but nights tend to be colder.
Interesting. Why does Augusta have such a big range?
Areas 3-20 miles inland from my area might have ranges 1.0-1.5C/3F hjigher, but I don't have any stats to know for sure. Most months stay close to the average, although I have seen monthly averages of 15C/30F. The diurnal range is higher than the yearly range -something reasonably common in NZ.

I really dont know. It would be interesting to find out if anyone has any idea why. Not only Augusta, but that whole region in South Carolina has very high diurnal range for a humid, low elevation area.
Well it's not too close to the coast, that area of GA up into NC away from the coast and mountains is drier than parts to the west and the mountains. Under 45 inches where Atlanta has 50+ and the N GA mtns reach 70 and above. I didn't see any other data on humidity. I live nearby in Atlanta where a 20-25 degree swing is normal. It's really not that humid a lot of the year. Clear nights (like right now) with low winds easily drop temps 30 degrees here. Augusta can get some cooler temps than surrounding areas because of the Savannah River valley but I'm not sure how often that matters. While temps generally decrease with elevation, a 100 ft difference won't make as much a difference but it is enough have cooler, denser air sink into Augusta from the outlying areas (Augusta is along the "Fall Line" between the Piedmont Plateau and coastal plain). I'd be curious to know the cloud cover averages. That can be a huge difference maker. I know they get less rain, seems like cloud cover would be less also.
Although not that close to the coast, it's around 45-50km inland, Richmond (a Sydney suburb) has a relatively high diurnal range, mainly in the winter (this is its upcoming week forecast):
Valbonne, France is only a dozen km from the coast, not far from Nice, and I've seen some impressive diurnal ranges there, in any season, at my friend's place. He used to live in the middle of a forest in a low population density area though. The area is much drier than Nice (in terms of %RH, not necessarily precip).
I've seen 0/21°C in December there (nearby Cannes recorded 6/20°C on that day (the 16th), and Nice 6/18°C). I remember it well because it was the day following my birthday night at his place; late at night we were freezing our asses off smoking outside, checked his PWS and it was, literally, freezing.
In summer, while Nice was enjoying its typical balmy 21/28°C, I've seen it go from 10-12°C to about 35°C, still at his place. Impressive really.
I wish the area had climatic data. Wouldn't be surprised if it were like 1/14°C in winter and 14/32°C in summer.
When I worked in the same area (Sophia Antipolis) in spring once, it wasn't unusual to wake up and leave Nice where it was 15°C at 8am, arrive there at 9am where it was 10°C, leave at 6pm when it was 26°C, and arrive in Nice where it was 20°C.

True dat. Most clear mornings this winter the difference was more than 5°C between where I live near the coast and where I work half a dozen kilometers inland. There was frost every other morning in the dead of winter. And on warm days, when I check the official temps at Nice airport, I tell to myself, "this can't be, I swear it was much warmer". Today was one of those days. No way the high was only 24°C in Sophia Antipolis.
