Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

You may need to stor for more than a day. Wind actually often has pretty strong seasonality, with one half of the year producing close to 2/3 of yearly power, and the other half the rest. Monthly variations in some sites can be 3:1 between the best month and the calmest. So to have smooth production over the year (admittedly a tougher requirement than may be needed in practice) might require a couple months' worth of storage.

How does that seasonality correlate with the seasonality in energy demand?

It depends. (sorry, no better answer)

We could always learn to arrange our life around the seasonality of renewable energy. Tapping into pumped storage must have a price, different from just using the energy as it is produced. Making that price explicit would "teach" us to adjust our behaviour appropriately.
