The honest answer to when you should fly Barcelona to Sofia is mostly about weather and demand at the far end. On three years of daily observations at the arrival airport, Jun, Aug-Oct gives the most comfortable combination of temperature and rainfall in Sofia.
Averages below come from three full years of daily readings at Sofia’s main airport, not from a seasonal generalisation. The warmest month is July (average high 31°C), the coolest is January (average low -2°C), and the wettest is November (99 mm).

Sofia runs 1 hour ahead of Barcelona. 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 Barcelona–Sofia, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
