I just spent some time on Google Maps and holy moly you guys are 100% right. Every single location that i dropped down in it was foggy and cloudy. It constantly looks like it's going to rain and yet it's the driest capital city on the planet. How bizarre.
I feel really hard done by. I went to Lima and it rained on me. Not much, but it did! We were told it's always cloudy but never rains, but don't worry, you're going to Arequipa next and that has 360 days' sunshine a year!
I was completely shocked by the driest capital city. I only got it by guessing random cities. If I had done it methodically I would have guessed at least 100 cities before that one. After looking it up it seems to be a unique climate. It's extremely cloudy during the winter months with nearly complete cloud coverage all season but no rain.
It's very weird. Near the equator, on the coast, and you need a sweater. Garua, I think the phenomenon is called (maybe only called that in Peru?). It lends a grey grimness to Lima most of the time.
Garua is drizzle. Yeah, Lima is very humid and the climate is weird (can be cloudy and foggy in a part of the city but sunny and burning hot only 4 km away in another part of the city), but it rarely rains for real. Mostly drizzles. I live in Lima so I'm sure.
Especially since Riyadh spelled correctly on JetPunk always leaves a hanging H to muck up the next answer so I always just type Riyad. That didn't work and I swore I hadn't typed it.
Exactly, El Nino mostly affects northern Peru in terms of rainfall. Lima generally remains under the influence of the cold Humboldt ocean current, which causes the city to have a very dry and, amazingly, as idontkn1 mentions above, a very cloudy climate at the same time!
The nearest misses are Yerevan (29.6 cm), Kabul (31.2 cm) and Astana (32.0 cm). N'Djamena and Mogadishu get 51 cm (almost as much as Copenhagen!) and 42.9 cm of rain every year respectively, which falls mostly within a period of 2-3 months in each city. The reason they (and other capitals of Sub-Saharan Africa) seem to get less rain than they actually do is the high evaporation rate due to the extremely high temperatures!
If you have reached 60 on jetpunk and you don't know where Riyad is, then you must have inside connections. I could understand you demanding the spelling of Saudi Arabia's capital as مدينة الرياض
but to get your knickers in a twist over something so irrelevant is silly.
Lots of people seem shocked by Lima and Santiago, but given that lying between them is the driest desert on Earth, they don't particularly shock me. Praia's the one that surprises me - I get that you can have a very dry climate near the coast if there are mountains or desert in the windward direction, but in Praia's case the sea is close in every direction and it sits deep in the tropics. I suppose dry winds carry over from the Sahara and don't pick up much moisture as they blow over the sea.
The Wikipedia page on Gaborone offers two widely different sets of precipitation data, the one, as you said, totalling 18.97 cm and the other a little less than 50 cm. Given the annual temperature and rainfall distribution, the former would mean that Gaborone should be in a complete desert, which is not the case, so I would trust the latter.
I was surprised that Ulanbataar made the cut. The last time I was there it rained more than I have ever seen before. Streets were completley underwater and our hotel basement was flooded.
I'm honestly surprised about Lima. I've been there twice and it drizzles almost every day especially during winter. I thought it would have added up to at least a couple cm per year..
But perhaps even more surprising is the absence of Windhoek.
Where is Riyad?!
