Thank you everyone you have been very helpful. Squid Lips that graph makes it so easy - perhaps every missus would appreciate having it saved in her favorites - or stuck on the fridge as the weekend approaches

Poor baywavebill is missing this weekend's epic conditions to visit our son interstate and conditions aren't looking good where he's heading so he didn't even take any gear with him. I wouldn't want him to miss another good weekend of windsurfing whilst he's on holidays.
Mr love, perhaps your family is young; the "compulsory" family outings tend to settle down a bit as the kids get older.
Old Salty, what goes around comes around - I'm a lucky missus
