Is there any truth in the proverb “wind from the east, fish bite the least”?

It’s likely that this expression originated in the UK on the east coast 500 or so years ago, where some fishermen suspected a trend whenever a cold easterly/north-easterly wind was blowing. Despite the onshore winds (which usually bring good fishing), poor catches led the fishermen to conclude that the fish simply weren’t interested in taking their bait whenever an easterly blew in. This proverb has spread to other parts of the world where, in reality, myriad factors can result in poor fishing, including the time of year, tide, weather, bait used and coastal position. It’s only your own experience of the area you fish in that will determine whether this saying holds true or not.
