i will be in grafton may/june and not sure what to pack for clothing what are the tempertures for this time in celsius
marydawn, I live 30 miles away, and I wouldn't know what to pack either for all of May and June. You will have daytime high temperatures, in Celcius from 18 to 32. The weather can change significantly, even within a day, if a cold front rolls through. Bring clothes for hot weather, then have sweaters and jackets that you can layer over them.
We are having heavy rains this month, and there were heavy snows up north this winter, so I hope Grafton isn't adversely affected by river flooding during your stay. It's a very scenic area when dry.
