The bar and line chart illustrates the relationship between average monthly temperatures and bathing suit sales in New York City during the first half of 2012. Overall, it is evident that temperature and revenue do not follow a perfectly linear correlation, as sales peaked mid-spring despite temperatures continuing to rise into June.
In January, temperatures stood at 31°F, with sales reaching 100 hundred thousand US$. Over the next two months, temperatures rose gradually to 38°F in March, while revenue saw a steady increase to 150 hundred thousand US$. April marked a dramatic shift, as sales surged to a peak of 290 hundred thousand US$, even though the average temperature was only 49°F.
Following this peak, the trend for sales reversed sharply. By May, revenue plummeted to 85 hundred thousand US$, and it fell further to a low of 20 hundred thousand US$ in June. Conversely, the average temperature continued its steady climb, reaching 59°F in May and peaking at 65°F in June. Consequently, the highest sales figures occurred well before the warmest month of the period, indicating that peak temperature does not necessarily equate to peak bathing suit demand.
