Exceptions being the Monsoon lands and the west coast of US especially the cities of San Francisco and Los Angeles in California. In the southern Hemisphere, it is the coldest month. Let’s discuss Animal-Pros in a bit more detail.
Throughout the Northern Hemisphere, July records the highest temperatures of year. In the temperature buckle temperatures up to 95 F must be expected. Even as far North as 60 N, temperatures of over 80 F are the norm. The nigh time lows are around 75 F in the tropical belt, 65 in temperate zone and 55 F in the frigid zone.
The monsoon lands are a significant exception to this general rule, however. Here June is the hottest Month, particularly in South Asia where India and Pakistan are located. The cool monsoon winds hit most parts of the Indian sub-continent by the end of June and prevent additional rising of the temperatures. Because of this July is much cooler than if there were no monsoon.
The second exception is that the Californian coast, here due the cool pacific present, the temperatures rise very slowly and reach their peak by the month of August.
As the seasons are reverse in southern hemisphere, so the regions located here are passing through their mid-winter. The significant difference being that the winter is significantly milder than the winter of the Northern Hemisphere since this hemisphere has no vast continents like Asia and no channel is situated very far away from the oceans. Thus the continental effect is not that pronounced and the temperatures are quite mild. As an example, if we have a close look at some of the famous cities located in Southern Hemisphere, we discover that the winter is much less intense than that of the Northern Hemisphere. Sydney, in Australia records a high of 60 F in July (its coldest month) and a low of 40 F; which is quite equable. At Auckland, in New Zealand, which is located further south, the day time temperature rarely falls below 50 F and the nights are around 35 F.
In short, July is the hottest month in the Northern Hemisphere and the coldest in the Southern Hemisphere. The temperatures recorded at a particular station is highly determined by its distance from the closest water body is it a sea or an ocean.
