Also look at the "webbing". If it is green, don't bother buying the melon. Brown is good, means it is ripe or will get there.
Oh and look for dimples. You know, the places where IDIOTS shoved their finger hard on the melon to see if it was ripe then put it back. First, that doesn't work. Second those spots will rot and get fungus, not necessarily visible until you cut it open.
You can use the "thump" test on watermelons. If it sounds hollow it is ripe.
