Aircraft; Weather
When we were climbing out; I overheard that many different aircraft were leveling off early when they were unable to climb to their requested final. Both me and the captain looked at the FMS and saw in the climb the temperature was between ISA+15 and ISA+25. This caused us to burn through a lot of our extra fuel and even through we took off about 900 pounds over Min Fuel; between this and the Speed Restrictions going into ZZZ and the 45 mile downwind we had in ZZZ (I saw ZZZ1 out the window we were that far out) we landed just under our reserve fuel. The atmospheric conditions and ATC constraints made us burn through about 2;000 more pounds than we originally planned. The flight was never in jeopardy and we discussed that if there was any reason we were pulled off the approach or went around; we would immediately declare Min Fuel; but it was just a combination of many different things that led to such high fuel consumption.
A CRJ-900 First Officer reported a fuel burn of approximately 2;000 pounds over planned because climb temperatures were between ISA+15 and ISA+25 coupled with ATC delays.
