The two line charts demonstrate the mean temperature and total sunshine duration in a year in two cities of Australia.
Overall, Melbourne remains consistently cooler throughout the year, whereas Darwin experiences significantly higher temperatures. In terms of sunshine, Darwin reaches its highest levels in the middle of the year, while Melbourne records greater sunshine at the beginning and end of the period. Both cities show clear seasonal patterns.
Looking first at temperature, Melbourne starts the year at around 10°C, compared with Darwin’s much warmer 18°C. Temperatures in both cities then rise steadily, with Darwin reaching a peak of 30°C in August and Melbourne hitting a high of about 18°C in January. After this point, both cities experience a gradual decline, although Darwin ends the year at approximately 21°C – around 12 degrees higher than Melbourne.
Turning to sunshine duration, Melbourne begins with roughly 10 hours of sunshine per day, four hours more than Darwin. However, Melbourne sees a noticeable drop to about 6 hours in May, and this level remains stable until September. In contrast, Darwin’s sunshine hours climb sharply from 6 to a peak of around 11 hours in June, before staying almost unchanged for several months. From September onwards, Darwin’s sunshine decreases gradually to 8 hours, while Melbourne’s rises again to end the year at roughly 10 hours.
