There does not seem to be many years in living memory where extreme weather has not affected a region of the world. The impact on tourism due to extreme weather is only too evident, and in some cases it takes a while for the regions to get back on their feet. Extreme weather hits the islands of the Caribbean and the southern states of America year in year out in the form a hurricanes and tropical storms. Storms such as Hurricane Katrina not only ravaged the Caribbean islands but tor the city of New Orleans to pieces causing widespread damage and the loss of life. Tourism in the region almost ground to a halt simply because the city was underwater for several weeks and any attractions and hotels were either completely destroyed or out of action. As a consequence the city and the surrounding region suffered dramatically from the loss of revenue gained by tourism for much of 2005 and 2006.
Extreme weather can take many different forms, as I have mentioned above hurricanes are a common occurrence in the Caribbean and the southern states of the USA but other regions of the world suffer the exact opposite. Drought is common in Africa and in Australia; this year alone has seen roughly 12 million people displaced in Somalia, Ethiopia & northern Kenya as the result of the worst drought in 60 years. Although tourism in these regions is scarce the fear the Drought may spread south into Kenya's more touristy regions has been a factor and had a lot of people cancelling their holidays scared of what may happen. Drought means starvation as crops fail to materialize leading to famine which is many cases leads to violence and conflict.
As global warming seems to becoming more of a presence in the world we live in, extreme weather is a consequence entirely of our actions and it's usually the poor, impoverished nations who feel the full force of the effects. The problem with extreme weather is it's typically very unpredictable and even when it can be predicted it's difficult to prepare for the absolute worst. Once a destination starts being branded as a risky destination to travel to because of extreme weather that's when the tourism industry begins to tail off and year by year the country receives fewer and less visitors. The main reason many of us travel abroad is for good weather, whether it's a summer holiday or a winter break skiing in the Alps, quite the weather plays a deciding factor in where we choose to travel. If a destination has a reputation of extreme cases of bad weather it's highly unlikely we are going to risk a two-week holiday there when there are plenty other destinations in the world without the weather problems. As a country that experiences extreme weather there is very little you can do about the tourism industry, you just need to rely on the weather gods to help you out a little bit.
