Yeah, just checked. Buenos Aires summers are hotter and longer, but are overall not so different (considering NY is a much colder city).

While this are temperatures from May till September in NY:

May: 54.2 / 70.9
June: 63.3/79.0
July: 68.8/84.2
August: 67.7/82.4
September: 60.3/74.7

In BA in the equivalent months (November till March) temperatures are:

November: 60.6/77.5
December: 65.1/82.6
January: 68.7/86.7
February: 66.9/83.7
March: 62.6/ 79.5

As you can see, BA is hotter, but not that much hotter (considering how different this cities weather is in winter, for example) . NY is slightly more humid, but both cities are around the 70% in summer. The "feels like"in BA is scandalous (33-38 all Janaurys, every day).

The numbers for NYC looked a bit off for September…so I checked since I had time to kill here at work. The average high in Sept is 76 F not 74F. The difference is not large, but here are the official numbers for NYC according to their NWS:

National Weather Service Climate


May till September in NY:

May: 54.2 / 71.6
June: 63.6/80.1
July: 68.9/84.9
August: 67.9/83.4
September: 60.8/76.0

It’s amazing that in the main three summer months…there is only about 2 F difference in the daily highs between NYC and BA…yet BA is located 500 closer to the equator.

Columbia, South Carolina is about the same latitude as Buenos Aires and both are on the east coast of the continent. Their mean temperatures are about the same (63°F) but Columbia's summers (92/72) are much hotter than Buenos Aires while the winters are much cooler (55/34; cooler than Mar de Plata!)

South America is just less extreme than North America

Thats true. One of the main things i learned in weather forum is how extreme North America is compared to SA, and how brutal is the summer there almost everywhere. While here, in Argentina, aside of the tropical northern places and the big cities in norther of the humid Pampa (including BA, Rosario, Cordoba, Mendoza) summers are mostly "cool".

Also, i imagined that winter in Patagonia was freezing, but compared to almost everywhere in USA, Patagonia could even be considered mild!!

Overall is like that, northern hemisphere haves a much biggest range in temperatures than SA.

Care to compare the winter temps as well?

Chester, winter is waay warmer in BA. Overall all seasons are waay warmer in BA than in NY, except for summer that is only a bit warmer in BA.

im gonna go find the stats in wikipedia and post them.


Winter months in Buenos Aires:

June: 45.7/60.1
July: 45.3/57
August: 48/63.1

While, NY:

December: 31.6/42.9
January: 26.2/38
February: 28/41


So, we see that BA its almost 20 farenheit warmer than NY in winter!

Average year temperature of BA is 64 farenheit, while NY is 54 farenheit. So, yeah, its considerably warmer.

South America is just less extreme than North America

No doubt the two biggest landmass on the planet – Asia and North America are the kings of extreme temps in the world.

However, one of the interesting things I’ve read about and even noticed - when you compare a Northern American station and a South American station - the differences in monthly mean temps decrease with decreasing latitude – especially in the cold season. By this, I mean if you compare a South American and North American station at 55 latitude - you might find there is a 35 F difference in the coldest months….if you compare a North and South American station at 40 latitude the difference in the coldest months might be 25 F….and once you get down near 30 latitude the difference might be less than 5 F. The same would be true in East Asia I would guess. Meaning that Hong Kong and a location at similar latitude in South America would have mean temps in winter closer than a location in Manchuria and South American at similar latitude.

Your example of South Carolina above is a good one. Buenos Aries is on the coast – Columbia is not. However, if you find a station on the coast near the same latitude – you can see that monthly mean temps are not much different in the cold season. Take Buenos Aires and Charleston South Carolina –

BA: BUENOS AIRES/OBS. CENTRAL, Weather History and Climate Data

Charleston: CHARLESTON CITY, Weather History and Climate Data

I remember Trewartha used to have an index in his text that used a set of numbers to measure what he called the “Index on Continentality”. Apparently, while the annual temperature amplitude was the greatest in Asia and North American…the numbers decreased with decreasing latitude. I don’t remember if this occurred in both the cold and hot season, but my guess is that even the hotter summers of North America smoothed out with decreasing latitude.

The Southernmost city on the planet Ushuaia has winter temps comparable to NYC's:

June: 29.7/40.3
July: 29.5/40.1
August: 30.2/43.0

and a record low almost the same too -13F for Ushuaia vs. -15F for NYC.

Prince Rupert's at a comparable latitude to Ushuaia and has similar winters:

Dec: 41.2/ 30.6
Jan: 40.3/ 28.2
Feb: 42.6/ 30.0

Record low is similar as well (-11.9°F)

But, I'd much rather take a winter in NYC than either of the two other bleak places...
