Located on the side facing the wind or toward which the wind is blowing; the opposite of leeward.
From wind + -ward (a suffix meaning 'in the direction of' from Old English weard). The word originally nautical, still primarily used in navigation and weather.
Sailors have used 'windward' and 'leeward' for centuries to navigate—knowing which side the wind comes from is literally the difference between getting where you're going or crashing.
