Quick Question from an Aviation newbie

[Lkap13]

I live approximately 30 minutes drive from Newark Airport in NJ and planes pass over my house at frequent intervals. These planes all have about the same flight patterns as they're all headed towards Newark, but the past week I've noticed that they all are flying at a much higher altitude than before. They're not flying high enough to be going to a different airport, and the flight patterns are still the same, so:
My question is, what could account for the sudden change in altitude for planes flying into Newark? I don't think it's weather, because the weather in Jersey has been 80 degrees and sunny the past month.

Thanks for your help

i'm not really sure...
if the planes are big or if they are jets then they would be flying higher
maybe not as many light aircraft are flying in the wintertime.


srry i couldn't be much help

Check the wind direction...they may be over flying and coming back into the wind.
