The proverb is "It's an ill wind that blows NOBODY any good." In modern terms it means "It's a bad wind that doesn't do SOMEBODY some good."

For example, a dry wind might be good for the florist, because it keeps fungi off roses, but it is bad for the wheat farmer because it keeps seeds from sprouting, because seeds need moist soil. A strong, cold wind might be good for a sailing ship, but bad for a beggar. But it's truly an ill wind that doesn't help anybody at all.
