Seasonal demand is the fluctuation in demand according to the time of year, season or cultural/religious events. Common examples of this are Christmas, Divali or Eid, where people purchase more gifts for people such as "Happy Holidays" cards and toys. Also, in Dubai, we tend to try and escape the country in winter and summer months raising demand for airlines. Seasonal demand is a recurring phenomenon.

Gifts I have received this Christmas include a Star Wars themed key torch, some fridge magnets of the same theme, some books and some shirts. These gifts would have likely been given to other people for Christmas also, and this tells me that there is a large demand for items such as this.

Demand changes because of the weather as demand can increase for umbrellas for example if it rains, and sun cream if the sun will shine. It can also change because of the customers, for example if a customer is from Europe they may not be interested in buying things like guns whereas in America there are many avid gun owners and the demand would be higher.

Other examples can include people who like things such as rock climbing. This event is more likely to occur in summer.
