Weird feel

So I went surfing for the first time in like two or three weeks yesterday and I did horrible, I went back this morning and the same thing. The waves were really mushy and were closing out so I get that it wasn't just me, but I felt really like awkward on my board, I usually feel great on it, I kind of felt like newbie again. I don't know if it was because I got used to the board I was borrowing last month in Nicaragua or what?
