What do you mean? Long periods of calm weather during cold temperatures is not unheard of in Finland and does cause issues at times due to amount of wind energy that has been built in recent times.

Beyond that wind for each location is somewhat seasonal so if you’re doing this for winter energy you pick areas with better wind in winter.
If you’re proposing seasonal storage as a viable option then cutting total storage needs by 90% (to handle a 10 day lull vs 90 day gap) is inherently cheaper.
Hell traditional hydro is well suited for such situations as annual output and storage is limited but nontrivial. Doubling output for 10 days isn’t nearly as problematic as trying to cover a 90 day shortfall.
