The line graph compares the average daily maximum temperatures recorded throughout the year in two cities in New Zealand (Auckland and Christchurch) and two cities in the United Kingdom (London and Edinburgh).
Overall, the New Zealand cities experience their highest temperatures at the beginning and end of the year, while the UK cities peak in the middle months. In addition, Auckland remains warmer than Christchurch for most of the year, and London is consistently warmer than Edinburgh.
In New Zealand, Auckland begins the year with an average maximum temperature of approximately 24°C, which gradually declines to a low of around 14°C in July before rising again to about 23°C in December. Christchurch follows a similar trend but at slightly lower levels, starting at roughly 22°C in January and reaching a minimum of about 11-12°C during winter.
By contrast, the UK cities show the opposite seasonal pattern. London’s temperatures increase steadily from around 7°C in January to a peak of approximately 22°C in July, after which they fall towards the end of the year. Edinburgh records lower figures throughout, rising from about 5°C to a maximum of around 18°C in midsummer before declining again.
In summary, the data highlights a clear contrast between the hemispheres, with New Zealand being warmer at the start and end of the year, while the United Kingdom experiences its warmest conditions in mid-year.
