The honest answer to when you should fly Madrid to Santorini is mostly about weather and demand at the far end. On three years of daily observations at the arrival airport, May-Jun, Sep-Oct gives the most comfortable combination of temperature and rainfall in Santorini.
Averages below come from three full years of daily readings at Santorini’s main airport, not from a seasonal generalisation. The warmest month is July (average high 31°C), the coolest is February (average low 12°C), and the wettest is December (60 mm).

Santorini runs 1 hour ahead of Madrid. Travelling east is the harder direction to adjust to, so if the trip is short, an early departure that lands in daylight is worth more than a marginally cheaper overnight.
We publish observed fares for this route when we have them, and say nothing when we do not — there is no estimate on this page. What holds regardless of the route:
Midweek departures are consistently cheaper than Friday and Sunday on most routes, because that is where demand sits rather than because of any pricing trick. Where we have observed fares for Madrid–Santorini, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
