And from the same table, high-altitude La Quiaca has very low rainfall and 9.3 hrs/day annually.
It gives 6.6 hrs/day for BA, lower than other sources it seems.

I looked at the Wikipedia data on La Quiaca, and that is a very interesting climate, certainly the best in northern Argentina by my standards . It certainly has pleasant enough summers, though the winter temperatures reveal a definite Bolivian influence.

Curiously enough, La Quiaca comes the closest of any climate I've seen yet of a new idea I've had of creating a fictional "Mildlanta". That's the counterpart to the current climate of Atlanta (or "Hotlanta") that will be closer to my own version of mildness (as opposed to hotness - get it?). Basically, I'm trying to create a more pleasant version of a subtropical or temperate climate, one that would also fit the desires of many who want to move to the Sun Belt but are put off by the summers. I've been looking at local forecast videos of Atlanta, and trying to get a handle on their typical weather patterns so that I can modify it.

So far I've come up with a dry, sunny winter that features frosty nights and warm days, like Atlanta had in the early part of December 2010 - 23/45F and sunny would be a typical day in "Mildlanta" (it'll get a different name when it's finished). Light amounts of snow would occasionally fall, maybe averaging 5-10 inches per season. I'm planning on there being more snow than rain, which grades towards the Coloradan pattern of precip coming when it's cooler. For the summer I've decided to make it like the winters in the warmest of the Gulf states only with more gentleness added, if that makes any sense. Basically high 60's for highs and around 50F for lows with prevailing sunshine, interspersed with showery periods that bring light amounts of rain and most of the year's moisture. It'll be just enough to maintain a forest cover.

Of course, they still would get occasional summer heat, occasional colder nights in winter, and occasional heavier snows, but that would be the prevailing weather pattern. La Quiaca reminded me of that dormant project.

And about La Quiaca, I wonder what Sophie thinks about it. It seems to be in the general vein of what she likes.

La Quiaca does indeed look interesting. For me the high sun and low precip. are big plusses.

Downtown is also the primary place that gets these fogs. Other parts of the city don't get as much or intense of a fog as downtown. As far as I know, the NWS station is in Downtown.
I have experienced very thin cloud of a foggy/misty type in Antofagasta - also Arica - and the sun was still shining very strongly through it.
