Katherine Webb -- February Is BIKINI SEASON

Yeah, it's still technically winter ... but it's beach season for Katherine Webb.

Mrs. AJ McCarron hit the beach in Alabama with her baby son, Raymond -- and while he's cute and all ... Katherine kinda stole the show.

As for AJ, there are talks he could be traded during the off-season. Based on these pics, we're hoping he lands in a place with a beach.
