Frist time,going in june too.Are best bet is to have them handy,Weather is looking like things are heating up,so we might get a good one but due to rapid changes anything could happen.Your worst bet is that you are unsure about moveing on up,desend back down,so if your doing a 1 day take the axe/crampons so you can make it safe to the summit,Good Luck and be safe.
