Will be in Europe in July and have been interested in doing the WHW, however have heard midges are terrible during that time of year

Is it worth doing the WHW in July? Or is it better to wait until few year where I can plan it to be before July? Just trying to potentially knock couple things off my list while in Europe.

Are midges really that bad to potentially skip doing the WHW in July? Are they present throughout the entire trail, day and night?
