Representative figures from each country's largest city. High / low are average daily temperatures (°C); “Feels” allows for humidity.
Iberian Peninsula (Spain & Portugal)
By late spring the peninsula settles into a reliably mild pattern: Lisbon and the Algarve are comfortably warm, Barcelona pleasant, while inland central Spain warms significantly with increasingly hot afternoons. The Balearic ferry season ramps up and beaches begin to draw crowds; this is excellent shoulder-season value before peak summer. Pack sun protection and light layers, but expect occasional warm nights in Madrid and Seville and sea breezes that make coastal towns enjoyable.
Southern France & the Riviera (Provence, Côte d’Azur, Languedoc)
Late spring finds the Côte d’Azur pleasant and increasingly sunny: beach days become possible, coastal walks along the Promenade des Anglais or Cap Ferrat are delightful, and inland hill towns warm up. The mistral is less frequent and outdoor markets brim with produce and herbs. Travelers benefit from booking hotels earlier for late May-June weekends when French holidaymakers begin to arrive.
Italian Peninsula, Sicily & Sardinia (Italy)
High summer weather arrives in July with long, hot days on the mainland and islands: Rome, Florence and inland Sicily frequently top the low to mid-30s°C, while coastal areas on the Tyrrhenian and Adriatic get cooling sea breezes. Sardinia and Sicily are especially popular for beaches - expect lively ports and fuller ferries - while mountain refuges in the Apennines provide cooler retreats. Travelers should plan outdoor sightseeing for mornings and evenings and carry sun protection and water.
Adriatic & Balkan Coast (Croatia, Montenegro, Albania, Slovenia, Bosnia-Herzegovina)
High summer in July and August brings hot, sunny days and busy beaches across Croatia’s Dalmatian coast, Montenegro’s Budva riviera, and Albania’s Riviera; coastal towns are lively with boating, festivals and crowded harbors. The Adriatic is generally calmer and swims are pleasant, but inland areas can be significantly cooler due to elevation. Book accommodations early for July-August and expect bustling ferries and packed promenades.
Greece & the Aegean (Greece mainland, Cyclades, Dodecanese, Crete)
High summer means strong sun and frequent Meltemi winds in July and August, especially in the Cyclades, which keep temperatures more bearable but can make sea passages rough. Mainland Greece, Athens and the Peloponnese are seriously hot - often mid to high 30s°C - and crowded as Greeks take their vacations. Travelers should plan morning and evening activities, book ferries and accommodations early, and bring sun protection and a windbreaker for choppier afternoons.
Malta & Cyprus (Eastern Mediterranean islands)
High summer brings hot, dry conditions: July and August often exceed 30°C, especially inland in Cyprus where 35-40°C is not uncommon in heatwaves, while Malta remains warm and stifling in sheltered urban streets. Sea breezes help along the coasts, and both islands are at their busiest with beach tourism and festivals. Travelers should avoid strenuous midday activities, drink plenty of water and book accommodations early.
