The line graph shows estimated sales of gold in Dubai for 12 months in 2002 in millions of dirhams. There were two main seasons for gold sales.
The main season for sales is in the December to May period. Sales were consistently above 200 million dirhams per month, rising sharply to a peak of 350 million dirhams in March. However, for the next four months, sales declined steadily, reaching an annual low of 120 million dirhams in July.
In August, there was a sudden increase. Sales almost doubled, rising from 120 million dirhams in July to 210 million dirhams in August. This was followed by a drop in September, back to the July figure.
From September to October, sales recovered, from 120 to 180 million. In October and November, sales remained steady, and there was a small increase in December to 190 million dirhams.
In conclusion, the main sales period is in the early part of the year, slumping in the summer, except for a sudden increase in August.
