That's right. Even thought they tipically define the rain season from december to april aprox, you should be prepared for rain the whole year, even for heavy rain, storms, etc.
The main difference between summer and winter is the water level at rivers. Since all amazonic rivers begin at the Andes, and there is an actual rainy season in summer at the mountains (dec-apr), water level is considerably higher in the jungle, rivers are wider. So, if there are some beaches at rivers, they disappear during summer. But I wouldn't those beaches as a decision factor to choose when to go to the jungle. There are nice beaches though not extraordinary beautiful, or at least those I knew.
