Big jumps in pressure distribution over surface

Hello. I'm trying to analyse the flow over a semi-cylindrical structure. I have found that on the windward edge the pressure varies wildly between neighbouring cells, with the pressure increasing and decreasing rapidly in a non-physical manner. I was wondering what would be the cause of this error, and how I would go about fixing this. I'm using the LES Smagorinsky turbulence model, if that is relevant. Some screenshots are attached. Thanks.
