Breh, I'm from Houston originally. It gets hot there, but they dont really see the extreme temps 105+ like us. And Houston is humid b/c of the gulf, which is not hard on allergies/sinus like Dallas. Dallas is dry heat mixed with a bit of that humidity. When I'm in Houston, I sweat, but I'm alright.
And it gets cold as hell here. It get's colder(lower) here on average then it does in like Oregon or Washington. For real, look it up.
i dont think our humidity is anywhere near as bad as some would like to make it seem. when it get on this 100+ shyt especially it feel dry as hell. i aint knockin the heat at all i'm just sayin the humidity aint what yall makin it out to be. as far as winter go you aint budgin me a damn bit. coldest winter i can remember was my sophomore yr in high school, and it was down in the 20s then. i remember been spendin my jr and sr year off seasons for football hot as hell, tryna come out in a hoodie and sheddin it in 70 degree temperature and shyt, its been that way ever since. we might get that rare ice storm everynow and again but be serious. i doubt dallas has dropped below 20 in the past decade or so
