Gold Yearly Seasonal Pattern Since 1977
The green bar on the chart below shows that September is the seasonally strongest month of the year for gold prices based on data since 1977. It follows the 2nd strongest month, August, but immediately precedes a sharp one-month seasonal decline in October, the 2nd weakest month, before the seasonal trend improves between December and February.

The height of the green bar indicates that, on average since 1977, gold prices have risen by 2.02% in September. The red line shows that, also on average since 1977, gold prices have plotted a positive September close 63% of the time, the highest incidence of a positive close for any month during this period.
