wlasnie dostalem odpowiedz na moje pytanie od kolesia z grecji, moze i was zainteresuje:
"Don't be surprised if it turns out that you can climb in your T-shirt on Christmas day - good weather is no rarity on Kalymnos in the winter. Rainy days are few and periods of rain usually only last for a day or two. The Archi and neighbouring crags are the most suitable at this time of year because they are sheltered from northerly winds and get most of the sun from midday onwards.
However last 2 years Xmas holidays were on bad whether. Climbing was possible about half of the days. We hope this year Xmas will be better as the older years.
Note that in Massouri, just a few Restaurants are open throughout, as are some of the hotels and 2 mini markets. However at Pothia ( a big city with 15.000 people) everything is alive and open.
Between Dec and Jun I suggest you Dec. "
