May offers reliably milder weather across much of Western Europe and is ideal for city touring, coastal trips and early hiking in lower alpine valleys. Southern France and parts of the interior can be pleasantly warm; prices and crowds begin to rise toward the end of the month.

Average temperature across Western Europe in May.
United Kingdom & Ireland
May offers warmer, longer days and an often-pleasant mix of sunshine and brief showers; averages across England and Ireland are roughly 12-18°C and the countryside is lush. Wildlife season is good for birdwatching in Norfolk and mountain wildflowers in Snowdonia; city terraces open up and festivals begin to populate calendars. This is a smart shoulder-season to visit: fewer crowds than summer but pack a light sweater for cool evenings.
Netherlands, Belgium, Luxembourg, Northern France
May typically delivers pleasant, mild weather-averages around 13-18°C-making it one of the best months for cycling and city walking without summer hordes. Festivals and outdoor cafés expand in Amsterdam and Brussels; the coast warms enough for bracing beach walks in Zeeland and Normandy. Always carry a light rain jacket: late-spring thunderstorms still occur but are usually short-lived.
Paris, Loire Valley, Burgundy, Champagne
May is often one of the loveliest months: daytime temperatures commonly 15-20°C, long light evenings and blooming gardens (Paris’ parks and Loire estates) are excellent for walking and cycling. This is an ideal month for wine tasting in Burgundy and Champagne before the heat of summer, with manageable crowds and pleasant outdoor dining. Pack lighter clothing with one warm layer for cooler nights in rural guesthouses.
French, Swiss & Italian Alps
May brings rapid green-up in valley floors-meadows bloom and lower alpine passes remain snowbound but accessible for scenery drives; temperatures in valley towns reach 10-18°C on sunny days. High-altitude trails and cols may still require snow skills and many mountain huts open later in the month. Paths can be muddy; hikers should carry waterproofs and check local opening dates for lifts and huts.
French Riviera, Liguria & Catalonia; Corsica & Balearics
May is reliably pleasant with daytime highs commonly 18-23°C and long sunny days ideal for city beaches in Barcelona and swimming along sheltered coves in Corsica. Ferries, restaurants and activity providers ramp up operations, making island-hopping and coastal boat trips practical. Pack warm-weather clothes plus a light sweater for cooler nights, and book ahead for weekend marinas and popular coastal hikes.
Brittany, Bordeaux, Basque Country, Galicia & Northern Portugal
May brings more stable, mild weather-daytime temps usually 15-21°C-ideal for cycling the Loire estuary, exploring Bordeaux’s vineyards and cruising coastal estuaries around Galicia. Sea temperatures are still cool but fine for energetic swimmers in sunnier spells; bring a wetsuit if you plan to surf. Accommodations become busier on long weekends, so reserve ahead for popular coastal towns.
Madrid, Andalusia, Extremadura, Algarve
May sees reliably warm, pleasant weather-highs often 20-26°C-with countryside trails and coastal promenades very attractive. Madrid is comfortable for city walking, and late-May begins the high-season trickle toward southern beaches; expect longer restaurant hours and active festival calendars. Pack warm-day/split-night clothing and sun protection for extended outdoor days.
