Nature directly or indirectly has impact on the sales of some products. Some products are seasonal in nature which means their peak sales are within their seasons. Examples ofv such products are raincoat, umbrellas, rainboots, cardigans, and wool fabrics are highly demanded during rainy season. You cannot expect to have more sales of those products during dry season. Also, during raining season some companies experienced low sales on their products. Companies producing drinks fall in this category.
