Yes, that's correct! Christchurch, located in New Zealand, has a higher latitude compared to many other places, which affects the angle of the sun's rays during different seasons. In the winter months, the sun travels a lower arc across the sky, resulting in less direct sunlight reaching the ground. This not only reduces solar heating but also contributes to cooler temperatures.
In addition to this, the longer nights and shorter days in winter further limit the amount of solar energy available to warm the environment. As a result, Christchurch experiences cooler atmospheric conditions during winter compared to areas at lower latitudes where the sun is higher in the sky, leading to more direct sunlight and warmer temperatures.
