As well as the usual monthly (sping and neap) and seasonal  (perigean and apogee) rhythms of  tides,  there is a 18 year cylce of differnce cuase by variations in the orbit of the moon. 2015 is a peak year in this cylce – so extra high tides.

Setting questions over fishing aside – this is a great site for free, yearly tide tables for the whole of the UK. Many sites restrict the tidal predictions offered, and try to sell tide tables.
