barograph Barograph Trace Spikes

[Mariner]

This is was recorded using an electronic barograph. This is about a 24 hrs period. I've been seeing spikes like the one the occurs at about x axis = 80,000 from time to time. Not 100% it's a real pressure change but I don't know what else it could be. The sensor is a BMP280, recorded about once a second. It's just outside my window, I don't think it's wind gusts.

 

Anyone else commonly seeing this on their barographs?
