Much of the autumn and spring rain falls in heavy downpours on a limited number of days, but in winter it is spread more evenly over many days. Summer receives very little rainfall, if any.

Environmental issues Lebanon, especially Beirut and its suburbs, suffered a massive garbage crisis, mainly from July 2015 up to March 2016. The issue began when authorities shut down the main landfill site originally used for Beirut's garbage south-east of the city and failed to provide any alternative solutions for months. As a result, garbage mounted in the streets in Greater Beirut and caused protests to erupt, which sometimes invoked police action. This problem was commonly blamed on the country's political situation. This garbage crisis birthed a movement called "You Stink" which was directed at the country's politicians. In March 2016, the government finally came up with a so-called temporary solution to establish two new landfills East and South of the city to store the garbage, while several municipalities across the country, in an unprecedented move, began recycling and managing waste more efficiently, building waste-management facilities and relying on themselves rather than the central government.
