A beautiful, sunny day.

It is a beautiful, sunny day, today.
Generally, June in Japan (or "Japan in June") is a (or "the") rainy season.  (Also, "in Japan, the rainy season is in June."  There are many more ways to say it!)
So, I did the laundry five times.  (I think you mean you "did 5 loads of laundry" otherwise, it seems like you washed the same things 5 times - very damaging! :-p ) 
The clothes dried well; I'm so happy.

いいです！

今日は、快晴です。
だいたい、日本の６月は梅雨です。
なので、洗濯を５回もしました。
洗濯物がよく乾くので、嬉しいです。
