weather in April/May

My wife and I are looking into a two month stay on the coast, the place we would get would be pretty tiny so curious about the weather. Coming from Colorado (been here a long time but grew up coastal Maryland) so used to the cold but mostly curious about the rain fall. Are we talking rain all day every day or afternoon showers or only every few days? I'll stop my non-descriptive rant, thanks for any help!

Edit (2): Would it be worth waiting for May-June? Looking at the Yachats or Arch Cape area due to rentals available but open to suggestions
