To me it all depends on how well I know the area. If I'm somewhere new and am just going to go sit on a hillside I'd probably stay in. However, if I know the area and most likely where the deer will be bedded I love using rainy days for walking. They can't hear you coming because the leaves are wet and rain is falling and they can't smell as good either. I can usually get within range of a few deer this way, but like I said you have to know where you're going.
