While most tourists pack away their summer clothes, seasoned travellers know that September unveils Europe's best-kept secret: perfect weather without the peak-season crowds. Guardian readers have revealed their favourite hidden escapes where summer's golden glow lingers well into autumn.
The Mediterranean's Best-Kept Secrets
For those seeking extended summer warmth, the Mediterranean offers countless possibilities beyond the usual hotspots. Readers consistently praised the lesser-known Greek islands where tavernas remain open and temperatures stay balmy well into October.
One reader described their discovery of Karpathos, between Crete and Rhodes, as "finding a forgotten piece of authentic Greece where summer never truly ends." The island's mountainous landscapes and crystal-clear waters provide the perfect backdrop for September swimming and hiking.
Italian Lakes Without the Crowds
Northern Italy's lakes transform in September, offering a more tranquil experience while maintaining summer's pleasant climate. Lake Orta, often overshadowed by its famous neighbours, received particular praise for its serene atmosphere and stunning Renaissance architecture.
"September at Lake Orta feels like having an entire Italian masterpiece to yourself," shared one reader. "The water remains warm enough for swimming, and the surrounding hills begin their beautiful autumn transformation."
Atlantic Coastal Magic
For those preferring Atlantic breezes, Portugal's Alentejo coast emerged as a standout recommendation. This unspoiled region offers empty beaches, world-class seafood, and temperatures that remain ideal for coastal exploration throughout September.
Readers highlighted the appeal of watching migrating storks from cliff-top restaurants while enjoying water temperatures that rival August's warmth. The combination of cultural richness and natural beauty makes this region a September standout.
Mountain Retreats in September Sunshine
Surprisingly, several mountainous regions received praise for their September conditions. The Pyrenees, particularly the Spanish side, offer ideal hiking weather without summer's intense heat. Readers reported perfect conditions for exploring medieval villages and enjoying mountain cuisine on sunny terraces.
One avid hiker noted: "September in the Pyrenees provides the perfect balance - warm days cool enough for strenuous hikes, followed by evenings comfortable for outdoor dining."
Urban Escapes with Autumn Charm
European cities also shine in September, with readers praising cultural capitals like Valencia and Ljubljana for their pleasant temperatures and reduced tourist numbers. The ability to explore museums, galleries, and outdoor cafes without summer's overwhelming heat and crowds makes urban exploration particularly appealing.
As one reader summarised: "September offers Europe's best version of itself - all the beauty and culture without the compromises of peak season."
These insider recommendations prove that with careful destination selection, the European summer can extend well beyond its traditional boundaries, offering unforgettable experiences in the continent's most beautiful corners.
