Los Angeles is in the Northern Hemisphere, while South Africa is in the Southern Hemisphere.
When Gao Guang and his group left Los Angeles at the end of September, it was autumn in Los Angeles, the most comfortable time of the year, and it was also spring in Postmasburg in September, the climate being at its most comfortable as well.
But now it's December, and Los Angeles has entered winter, yet due to its Mediterranean climate, the winters there are not too cold.
However, Postmasburg, which has formally entered the summer season, is different. The summers here are truly hot.
