One of my most important jobs as a Shakespeare actor is to find ways to enunciate some of his over-long sentences in a way that allows the audience to follow them just by listening.
In this case, it's not too hard. Shakespeare likes giving you oppositions, like "winter" and "summer". Put the stress there, and the audience will follow. And you don't need to breathe at the end of the line; it can flow directly into the next one.
