 The greater temperature ranges are found in the interior of the Canterbury and Otago regions, and especially Central Otago.Central Otago and inland Canterbury's Mackenzie Basin have the closest New Zealand has to continental climates, being generally drier (due in part to föhn winds) and less directly modified by the ocean.These areas can experience summer temperatures in the low 30s °C (high 80s/low 90s °F) and snow and severe frosts in winter, the latter exacerbated by hoar frosts in the river valleys and basins.
