Climate
Shinhidaka has a humid continental climate (Köppen Dfb) with warm summers and cold winters. With an alternate definition, using the −3 °C (27 °F) isotherm, Shinhidaka falls in the rare oceanic climate (Cfb) of the east coast of the continents due to the warm current of Tsushima. Owing to its slightly more southerly latitude, easterly aspect and location on the sea, snowfall is much lighter than in the major cities of western Hokkaido like Sapporo, Hakodate, Asahikawa and Wakkanai.[3] Precipitation in heaviest in the summer months when remnant typhoons may approach. Year-round sunshine, although less than in the Tokachi Plain, is also higher than western Hokkaido

Local attractions
- Nijikken-dōro (二十間道路), literally, road 20 ken (36 metres (118 ft)) in width, is an avenue lined with Ezo mountain cherry Prunus sargentii, (エゾヤマザクラ, Ezo-yamazakura) trees and a major tourist attraction of the town. The 8 kilometres (5.0 mi) road was created for a visit of the Imperial Family to the nearby Niikappu horse ranch in 1903. The ranch is under the jurisdiction of the Imperial Household Agency. It took five years to transplant trees from the local mountains to create the avenue. It was finished in 1916. Shinhidaka holds a cherry blossom festival yearly in May at the road in Shizunai ward.[12]
