I am not expecting to hit the officially claimed 51-52mpg but was hoping for much better than 32-34mpg on long runs.
What are your thoughts?

You are not alone! Most likely culprit would be the unseasonably hot weather.
With air conditioning on constantly, it will hit the consumption hard. In traffic and also on motorways with average shade air temps around 30 degrees Centigrade and with tarmac it will get hotter. I have the 2013 F25 30d MSport and my normal long run average is above 37.0 mpg, at present I am getting around 32 mpg.
