Residents in Broward County, FL experience flooding from either heavy rainfall or
high tides. During these events the
drainage systems may reach capacity due to the amount of rainfall received or because our stormwater management is limited by downstream conditions, including sea levels.
The rainy season in south Florida usually lasts from May-October where we receive 2/3 (41 inches) of our yearly average rainfall (57 inches)
High Tide Flooding (King Tides)
“Sunny Day Flooding” can also occur due to the highest tides of the year, which are also commonly refered to as King Tide events. Low-lying coastal areas of Broward County can be impacted by such flooding. These events often occur during the fall (August-November) with the peak tides usually occurring in October. Twice a day these tides will be so high that they can cause ocean water to back flow through drainage pipes, flow over sea walls, or even up through the ground due to the higher water pressure. These flooding conditions can last for several hours and can be very damaging to property, such as cars, due to corrosion from the saltwater.
King tides can be particularly dangerous and lead to significantly higher flooding if a high rainfall event occurs during the same time. An even higher threat of flooding can also occur during this time during a tropical storm or hurricane due to the associated wind and storm surge risks.
