I've wondered for a while whether "individual" swells of different periods but from roughly the same direction are additive? For example on sunday 8 a.m. for OCMD your swell plot shows 1.3 @ 9 ESE and 3.0 @ 6 S. so adds up to 4.3 feet but your surf forecast is knee-occ. waist
Monday 8 a.m. is 4.3 @ 7 S. surf forecast is waist - chest.
if the two swells sunday were diff periods but same direction...would that change things?
Aren't even "individual" swells like the monday 4.3 @ 7 from S. still an average (maybe concentration is a better word) of a spectrum of periods and directions anyway?
Sorry to throw yet another stupid question your way
