Book now or wait? First time flying Ryanair in June

First time using Ryanair and not sure how their pricing usually works. Planning a mid-week trip in early June from Milan to Madrid.

Right now there’s a Pig seat sale showing a €33.31 base fare. It was €29.90 yesterday, so it’s already crept up a bit. I’m wondering if I should just book now or wait and hope for another sale.

Do they run these sales often? And do they usually release more flights for summer later on? Right now I’m only seeing two flights a day on this route.

Trying to figure out if waiting helps or if this is about as good as it gets with Ryanair.
