One minute before pushback in OKBK we received our final takeoff weights. Approximately one hour later; while airborne; we received an ACARS message from the Dispatcher advising our final weights had been revised AFTER our take off and that our actual weight was really 1;864 LBS heavier! The extra weight would not have been critical since a temperature drop from to 36 degrees C (from 38C) gave us an approximate 10;000 LBS cushion before reaching our maximum allowable takeoff weight for this flight.My Observations: These final loading errors are unacceptable given the high ambient temperatures along with the usually tight weight limitations in which we operate in the Middle East. On this flight; the temperature was not a crucial factor and we were not maxed out on weight. Yet; as we all know; any extra weight can affect an aircraft's performance. A timely fix to this problem needs to be found.OKBK passenger and cargo loading procedures need to be re-examined with direct personal visits by Dispatch and Load Planning representatives until satisfactory procedures are attained. Hopefully; we can prevent any future incidents like this.
