Field notes
Mediterranean (Apennines) — meaningfully cooler than the Italian coast because of the 750m altitude (Mount Titano summit). Winter (December–February, 4–6°C average) is the rainy season with occasional snow on Titano. Spring (March–May) and autumn (September–November) are the cleanest shoulder windows. Summer (June–August, 20–23°C average) is warm and dry, meaningfully cooler than nearby Rimini on the coast. The microstate's altitude produces panoramic Adriatic-coast views year-round.
