Wash the cucumbers under cold water and pat dry with a paper towel.
Peel cucumbers, if desired - this is a good idea if they have thicker skins or a waxy skin.
Slice cucumbers using a sharp knife.
Place the sliced cucumbers into a large mixing bowl.
In a small bowl, combine mayonnaise, sugar, white wine vinegar, salt, pepper, and fresh dill.
Stir until the creamy dressing is smooth and well blended.
Pour the dressing over the cucumbers and mix gently to coat evenly.
Cover the bowl with plastic wrap and chill for 30 minutes before serving.
