While there's no one-size-fits-all answer as to how you can combat the effects of wind and current, the most important thing for you to recognize is that they exist in the first place. Before you even begin your approach to the dock, eyeball a flag or banner to see how hard it's flapping and in which direction. To get an indication of current, look for loose lines hanging in the water, water movement against pilings, or small bits of flotsam, like leaves and sticks, to determine which way and how fast the water is moving.
