Month-by-Month Guide
January
January is the coldest stretch in San Marino, with temperatures barely reaching 6°C (43°F) during the day and dropping to around 2°C (35°F) at night. You'll likely encounter some rain—about 50mm (2.0 inches) worth—and occasional fog that can shroud the fortress towers in an atmospheric mist. It's quiet up here, with few tourists braving the winter chill.
February
February doesn't warm up much from January—you're still looking at highs around 7°C (44°F) and lows of 2°C (36°F). The rainfall actually increases slightly to about 64mm (2.5 inches), and the wind on Monte Titano can make it feel considerably colder than the thermometer suggests. That said, on clear days, the views across the Apennines can be spectacular.
March
Spring technically arrives in March, though you might not notice immediately—temperatures creep up to 10°C (50°F) during the day but nights remain chilly at 4°C (40°F). You'll still get about 64mm (2.5 inches) of rain, and the weather can be quite unpredictable with sudden showers. The town starts to wake up from winter, with more shops and restaurants reopening.
April
April is when San Marino really starts to feel pleasant, with temperatures climbing to 15°C (59°F) and the landscape greening up nicely. You'll still need a jacket for the 8°C (47°F) evenings, and rain remains a factor at 58mm (2.3 inches), but you get more sunny days mixed in. Tourist numbers start picking up, particularly around Easter when Italian day-trippers visit.
May
May is genuinely lovely in San Marino, with daytime highs reaching 19°C (67°F) and everything in full bloom. Nights are mild at 12°C (54°F), though you'll still appreciate a light sweater after sunset. It's actually one of the wetter months at 71mm (2.8 inches), but the rain tends to come in short bursts rather than all-day affairs.
June
Summer arrives properly in June, with temperatures hitting 25°C (77°F) and warm evenings around 17°C (63°F) that are perfect for dining outdoors. Rainfall drops to a more manageable 53mm (2.1 inches), and you'll get long, sunny days for exploring the three towers and medieval streets. Crowds increase noticeably, particularly on weekends.
July
July brings the warmest weather of the year, with highs around 27°C (81°F), though the elevation keeps it from getting oppressively hot. Nights are comfortable at 19°C (67°F), and this is your driest month with only about 41mm (1.6 inches) of rain. Peak tourist season is in full swing, so expect crowds at the main attractions and book accommodations well ahead.
August
August is nearly as warm as July at 26°C (78°F), with similarly mild nights around 19°C (66°F) and minimal rainfall at 41mm (1.6 inches). The entire country feels busy as Italians take their summer holidays, and you'll find the streets quite lively in the evenings. The heat can occasionally feel sticky given the 70% humidity, but it's nothing compared to lower elevations.
September
September is many people's favorite month here—temperatures remain pleasant at 20°C (69°F), crowds thin out after Italian schools restart, and the light takes on that beautiful autumn quality. You'll see rainfall increase to 76mm (3.0 inches), but it's still mostly sunny. Nights cool down to 14°C (58°F), so you'll want that sweater again.
October
October brings proper autumn weather, with highs dropping to 16°C (60°F) and nights getting quite cool at 11°C (51°F). Rainfall remains significant at 71mm (2.8 inches), and you'll get more overcast days mixed with crisp, clear ones. The tourist season winds down considerably, giving the place a quieter, more local feel.
November
November is the wettest month in San Marino with 99mm (3.9 inches) of rain, and temperatures drop to 11°C (51°F) during the day and 7°C (44°F) at night. The weather can feel quite bleak with frequent rain and limited sunshine, and many businesses reduce their hours or close for the season. That said, if you don't mind the conditions, you'll have the medieval streets almost to yourself.
December
December is cold and often damp, with highs around 7°C (45°F) and lows near 3°C (37°F). You'll get about 61mm (2.4 inches) of rain, and occasionally snow flurries that rarely stick. The Christmas markets and holiday decorations bring some festive atmosphere to the old town, though many attractions operate on reduced winter schedules.
