Hi there, firstly have you adjusted the applied dosage between seasons and/or have you optimised dosage by conducting jar tests? You may need to change your poly for the two different seasons and you may need to consider pH adjustments, this can all be concluded with jar testing

pre-settling dams that double as raw water storage can sometimes help with reducing the sharp increases in NTU, if you have the space

does your treated water demand change between seasons? You may need to adjust for this as well

Hope this helps
