The bar chart illustrates the average monthly rainfall in Australia for the past year, while the line graph represents the average monthly rainfall over the last 40 years.
Overall, Australia experienced the highest levels of rainfall at the beginning and end of the year, with a significant decline in the middle months. Compared to the 40-year average, last year’s rainfall was generally higher in the first few months but lower in mid-year.
In detail, January recorded the highest rainfall of nearly 80 mm, which was slightly above the long-term average. February and March saw a gradual decrease, with rainfall levels hovering around 60 mm before declining sharply to about 40 mm in April.
From May to September, rainfall remained relatively low, particularly in August, which had the lowest recorded precipitation, below 10 mm. These figures were generally lower than the 40-year average for these months. However, rainfall began to increase in October and peaked again in December at approximately 60 mm, aligning more closely with the long-term trend and past data observations.
Overall, while last year’s rainfall followed a similar seasonal pattern, there were deviations in certain months, particularly in mid-year, where rainfall was lower than usual. This discrepancy highlights unusual weather patterns observed.
