Italy Weather, climate and geography
Weather & climate
Italy has a largely Mediterranean climate, though weather conditions vary noticeably by region due to differences in latitude, altitude and proximity to the sea. Northern Italy experiences greater seasonal contrast, while the south and islands enjoy warmer temperatures for much of the year.
Spring runs from March to May and is one of the best times to visit. Temperatures gradually rise, with daytime highs typically ranging from about 12–20°C (54–68°F) in March to 18–25°C (64–77°F) by May. Rainfall is moderate, landscapes are green, and tourist numbers are lower than in summer.
Summer lasts from June to August and can be hot, particularly in central and southern Italy. Daytime temperatures commonly range from 25–35°C (77–95°F), with heatwaves occasionally pushing temperatures higher, especially in cities. Coastal areas benefit from sea breezes, while the Alps and higher elevations remain cooler.
Autumn spans September to November and is another popular travel period. September remains warm, with temperatures around 22–28°C (72–82°F), gradually cooling to 10–18°C (50–64°F) by November. Rainfall increases in autumn, particularly in northern and central regions, but conditions are generally mild and pleasant.
Winter runs from December to February. Northern Italy and mountainous areas experience cold temperatures and snowfall, especially in the Alps and Apennines, while southern Italy remains relatively mild. Winter temperatures typically range from 0–10°C (32–50°F) in the north and 8–15°C (46–59°F) in the south. Ski resorts are active during this period, while major cities remain visitable year-round.
Clothing needs in Italy vary by season and region, but visitors can generally dress for a mild Mediterranean climate with some seasonal adjustments. Lightweight, breathable clothing is suitable for much of the year, particularly in spring and summer, while layering is useful in cooler months and in northern or mountainous areas.
During spring and autumn, light jackets or sweaters are advisable, as temperatures can change noticeably between day and evening. Rain showers are more common in these seasons, especially in northern and central Italy, so a light waterproof jacket or compact umbrella is recommended.
Summer clothing should focus on comfort in warm conditions, particularly in cities where heat can be intense. Evenings can still be pleasant, but a light layer may be useful in coastal or higher-altitude areas. In winter, warmer clothing is needed in northern regions and mountainous areas, where temperatures can drop below freezing, while southern Italy typically requires only light winter wear.
Visitors should also be mindful of dress codes when visiting churches and religious sites. Modest clothing is expected, with shoulders and knees covered, regardless of season. Comfortable walking shoes are strongly recommended year-round, as sightseeing often involves cobbled streets and uneven surfaces.
Geography
Italy occupies a distinctive, boot-shaped peninsula stretching into the heart of the Mediterranean, giving it an unusually long coastline and a remarkable variety of landscapes within a relatively compact area. Its geography plays a major role in shaping travel experiences, from alpine adventures in the north to beach holidays and island escapes in the south.
Italy shares land borders with France, Switzerland, Austria and Slovenia. It also surrounds two independent microstates, Vatican City and San Marino. To the west lies the Tyrrhenian Sea, to the east the Adriatic Sea, and to the south the Ionian and Mediterranean seas, giving Italy extensive maritime connections.
Northern Italy is dominated by the Alps, which form a dramatic natural barrier along the French, Swiss and Austrian borders. Italy's highest point is Mont Blanc (Monte Bianco), at 4,808 metres, located on the border with France. South of the Alps lies the fertile Po Valley, Italy's largest plain and an important agricultural and industrial region, home to cities such as Milan and Turin.
Running the length of the peninsula are the Apennine Mountains, a rugged spine that shapes climate, transport routes and settlement patterns. Central Italy features rolling hills, vineyards and historic hill towns, while the south becomes drier and more mountainous, with a stronger Mediterranean character.
Italy is also defined by volcanic landscapes. Active volcanoes include Mount Etna in Sicily, Europe's most active volcano, as well as Mount Vesuvius near Naples and Stromboli in the Aeolian Islands. The country's lowest point is sea level along its extensive coastline, which ranges from dramatic cliffs and rocky coves to long sandy beaches.
Italy includes two large islands — Sicily and Sardinia — along with numerous smaller islands, each with distinct scenery, traditions and natural environments. This geographical diversity means travellers can experience alpine peaks, wine-growing hills, ancient volcanoes and turquoise seas all within a single country.
