North Sea & Baltic Coast (Northern Lowlands)
By May the coast is genuinely springlike: apple blossoms in Schleswig and beach promenades in Travemünde fill with locals. Cruise and ferry traffic increases and islands like Heligoland start regular tourist services; bird migration is at its peak in the Wadden Sea, great for nature trips. Daytime warmth is pleasant but sea breezes keep it cool; sunscreen, a windproof layer, and advance bookings for weekend hotels are sensible.
Northeast & Berlin-Brandenburg (Potsdam, Mecklenburg Lakes, Rügen)
By May the countryside is lush and the Berlin cultural calendar swings into outdoor markets, long café terraces, and riverside barbecues. The Mecklenburg Lake District becomes prime for paddling and small-boat trips; Rügen’s chalk cliffs are attractive for hiking. Expect pleasant daytime warmth, occasional heavy showers, and bookable weekend attractions as locals take advantage of warmer weather.
Central Uplands & Harz/Thuringian Forest (Göttingen, Harz, Weimar)
By May the uplands are generally comfortable for hiking, with wildflowers carpeting meadows and clearer trails in the Harz foothills. Streams run strong from snowmelt, making waterfalls impressive and river crossings occasionally tricky after heavy rain. Accommodation availability increases and rural guesthouses gear up for the summer; bring mid-layers and a waterproof jacket for changeable mountain weather.
Rhine Valley & Rhineland (Cologne, Düsseldorf, Mainz, Moselle)
May delivers noticeably warmer days perfect for exploring Koblenz, strolling along the Rhine promenade, and sipping Riesling on Moselle terraces; tourist numbers rise but are not overwhelming. Thunderstorms are possible late in the month and can make for dramatic skies over the valley. Pack sun protection plus a light jacket for evenings and book castle-view vineyards for the best late-spring drinking weather.
Southwest: Black Forest & Upper Rhine Plain (Freiburg, Baden-Baden, Schwarzwald)
May is one of the best months: warm, sunny days are common in the Rhine plain and woodland trails in the Black Forest are lush and accessible. Outdoor activities - mountain biking, hiking, and visiting open-air thermal baths - are attractive; beer gardens reopen and spring festivals spread across the region. Expect pleasant daytime warmth and cooler evenings in the woods; bring a light jacket for late walks.
Bavaria & the Alps (Munich, Garmisch-Partenkirchen, Berchtesgaden)
May is often pleasantly warm in Munich and the foothills, with alpine meadows blooming and lower hiking trails opening; higher mountain passes can still have snow and limited services. Outdoor festivals begin, and quieter backcountry routes offer excellent conditions before high summer crowds arrive. Bring layered clothing, sturdy boots, and expect cooler nights above the treeline.
