I took a few pictures, including the one below, with a Gray Whale "photo-bombing" the rainbow seascape. (The spout is on the left side just below the horizon.)
The sky became very dark and I decided I should head back before getting soaked, but I took one more shot looking to the northwest from Bodega Head, with the waves rolling into Salmon Creek Beach.
I made it back to the office just in time. It started pouring rain a few minutes later. I think we recorded ~0.35 inches of rain within ~20 minutes!
