Why is Haiti so hot? (climate, warm, records, temperature)

[DoubleXAs]

This is just Port au prince:

the observed high temps in Fahrenheit from February so far:

90,90,88,90,88,90,89,90,92,93,91,91,92,91,91,92,90 etc
https://www.accuweather.com/en/ht/po...onyr=2/01/2018

and from last August in farenheit:

95,93,95,95,97,99,95,92,95,91,97,93,95,90,97,97,95 ,95,97,99,99 etc
https://www.accuweather.com/en/ht/po...onyr=8/01/2017

average high temp is 89 throughout the year :Port-au-Prince, Haiti Travel Weather Averages (Weatherbase)

All of Haiti's major cities basically hit 90 or above for the entire year. It resembles more of a dessert climate.

No other caribbean city is nearly this hot. Is it deforestation? I though the north east trade winds were supposed to regulate the temps a bit?

Thanks

Yeah, that must be it. The Haiti side of Hispaniola is a lot more deforested than the Dominican one, and also a lot hotter.

Definitely a dessert climate for tropical lovers.

That whole area of the world is hot and getting hotter. Think that is bad then try my area of Florida during the summer with a reverse west windflow blowing off 90+ degree water temps. The islands have it better than FL.

Average dewpoints and humidity also seem lower on the Haiti side. The west side of the island is prone to be drier and hotter because the trade winds blow from the interior rather than the ocean. The lack of tree cover probably makes things worse.

They cut down all the tree's and blew up all the coral reefs and have no bottom fish left.

Haiti is on the Lee side of Hispaniola, so they get downsloping winds which are drier and hotter than the upsloping winds in the Dominican Republic

These data look beyond suspicious, guys! Not unexpectedly, it seems that weather data for Haiti is poor/sparse. For instance, Ogimet doesn't report any SYNOPs from Haiti.

This webpage provides data from the GHCN. The period of records is complete, beginning in the 1850s. I guess data that old is often dubious and it is likely to have increased during the second half of the 20th century, yet it must be more on par with the typical Caribbean ranges.

Figures being slightly higher due to its location on the west side, opposed to the trade winds also makes sense, albeit not that hotter.

Could just be an over exposed/badly sited thermometer.

It could be. Is there any website that shows where the weather stations are located within the country?

Yeah the DR's southwest region is just as hot and dry.

Here is Jimani DR's averages:

https://www.weather-atlas.com/en/dom...jimani-climate

lowest : Jan : 89.6 high ------highest: July 95.5 high

Duverge, DR

https://www.weather-atlas.com/en/dom...uverge-climate

lowest: Jan: 89.8------------highest July 96.8

Can you elaborate on the role of the trade winds? From my understanding these are the mountain ranges in hispaniola:



I would assume that the trade winds would moderate Punta Cana's weather all the way to the east end, because of the lack of mountains, not making it ever get dessert like highs, but probably rarely ever dropping it to the 60's at night because off the warm ocean breeze.

I would assume that the the largest mountain range (pico duarte ) in the middle would make the places to its north (cibao Valley) very wet and rainy...and I guess cooler cause its on the windward side of the island.

and everything to its south/south west which covers almost all of Haiti and southwest DR, hotter and drier.




Is this correct?

My only question is there are still many mountain ranges in the southwest but I guess since they are smaller in altitude they dont have any effect on the temperature.
