The Sultans Trail from Sofia to Istanbul traverses several regions characterized by distinct climate patterns. Starting in Sofia and moving through western Bulgaria, you experience generally sunny weather with intermittent rain showers. Temperatures in this area range from moderate to warm, with average highs around 27-30°C and lows between 15-20°C. Precipitation is relatively low, although occasional rain showers are possible.

As the route progresses southeast into the Rhodope Mountains, cooler temperatures prevail, with highs around 22-25°C and lows closer to 12-15°C. This region sees a mix of sunny days and more frequent rain, including moderate to heavy showers, which is typical for its higher elevation.

Continuing into eastern Bulgaria and moving towards the Turkish border, the climate becomes warmer and drier. By the time you reach the areas near the border and into European Turkey, the weather is predominantly sunny. Average high temperatures are around 30-33°C, with lows in the 19-24°C range, and rainfall becomes infrequent.

Approaching Istanbul, the climate remains warm and sunny, with occasional bursts of rain. The influence of the coastal climate leads to slightly more humidity but overall remains similar to prior Turkish regions. Temperatures are comfortable for summer, with highs around 28°C and lows near 23°C.
