>>2651193>isn't it a general rule the further south, the hotter? Isn't the sun stronger?The general rule is closer to the equator is less seasonally effected, once you get to the tropics some places never go under 50F or over 100F. elevation can buck this trend to extent, which is how you can get tropical glaciers and temperate tropical climates.
>They both have a relatively early peak warmest day and it seems to more effected by the monsoon than anything. Isn't the monsoon strongest in Mexico? Big Bend is basically in Mexico.The indian summer effect in the 30s N is weaker than it is at higher latitudes in many places, especially Europe, but it is stronger than more southerly locations. The monsoon dumps the maximum amount of precipitation in US in AZ and NM, and in mexico it dumps its maximum in the Sierra Madre Occidental and the southern/mid Sierra Madre Oriental. W TX is in an aridification zone because of these patterns changing from what they were in the pleistocene and the new bands tend to go farther north and west, and W TX is rainshadow blocked by a 900 mile long coastal range in the path of the band (Sierra Madre Occidental).
>Chisos Basin is also surrounded by a basin, it's a minor basin in a mountain range not on a larger scaleDesert basins and non forested terrain in general heats up the surroundings anywhere, this is another reason why the lowly forested W TX mountains are also warmer on average than more densely forested areas. There are also some montane places in Mexico with cooler average temps and more snowfall than W TX because of elevation, more mild southerly latitude and high forest density and jetstreams.
>So basically what I'm saying is, it seems possible that the reason they have almost identical warmest month average highs is that the monsoon is strong in West Texas. But you said it's weakerThe monsoon precipitation and humidity level is weaker over W TX than it is over montane environments of AZ-NM, and even S UT.
