The best time to visit Polonnaruwa, Sri Lanka’s ancient capital and UNESCO World Heritage Site, is during the summer months from 六月至八月, when the dry weather and minimal rainfall create the perfect conditions for exploring its historic ruins. This period allows travellers to walk comfortably among the city’s impressive stone temples, palaces, and Buddha statues without the disruptions of heavy rain or muddy paths. The dry season also highlights the beauty of Polonnaruwa’s archaeological wonders, from the Gal Vihara rock-cut statues to the Royal Palace complex. Since this season coincides with peak tourist months, it’s wise to book your accommodation, transport, and guided tours in advance to avoid last-minute stress. Visitors can also combine their cultural journey with wildlife safaris in nearby Minneriya National Park, famous for the Elephant Gathering, which usually takes place during this same period. While the weather is hot, carrying water, sun protection, and wearing light clothing will ensure a comfortable trip. By planning, travellers can fully experience Polonnaruwa’s charm, uncovering centuries of Sri Lankan history in the most favourable climate. Whether you are a history enthusiast, cultural explorer, or photographer, June to August remains the ideal time to visit Polonnaruwa.
