The Sultans Trail from Sofia to Istanbul takes you through a diverse climate with variations as you progress along the route. Starting in Bulgaria, you can expect relatively cool temperatures in May, with average highs ranging from 15°C to 25°C. The weather during this part can be unpredictable, ranging from partly cloudy or sunny days to periods of moderate or heavy rain showers. Moderate temperatures around the lower teens are consistent, paired with potential bouts of rain, which varies based on elevation and region.

As you continue southeastward, approaching Turkey, the temperatures gradually increase. Average highs can reach up to 26°C, and the nights remain cool but comfortable, with lows in the upper teens. In this region, there is a notable trend towards sunnier days, particularly as you approach Istanbul. The likelihood of rain decreases compared to earlier in your journey, with occasional showers but generally clearer skies. Overall, the route provides a gradual transition from cooler, temperate conditions to warmer, more stable weather as you approach the urban climate of Istanbul.

This overview is for an early May start, walking the standard stages.
But, I'll be happy to make one specifically for this forecast.
