A synthesis of the most important features of the Bah´ıa Blanca estuary weather conditionsis presented in this chapter. The estuary is located in a temperate climate. In the last 100years mean temperatures oscillated around 15 C. Annual precipitation is variable, 712 mmand 540 mm were the maximum and minimum recorded mean annual rainfall. The spatialand temporal variability of the precipitation is significant. Few studies were performed on thesubject (Piccolo and Diez 2004). The winds are persistent all year round. Their annual meanvelocity is 22,5 km h−1. Strong winds, over 43 km h−1, blows over the estuary 54% of thewhole year. The estuary is affected by strong winds associated to distinct synoptic weatherconditions. The characteristic wind from the South, from the pampas, is called Pampero.It is associated with a cold front which crosses the estuary. The pampero is usually a dryairflow. The Southeastern wind, denominated ”Sudestada” causes rain, fog and causes manyproblems to the population due to its bad weather conditions. Finally, the most frequent windcirculation is from the North / Northwest. It is a warm and dry wind that originates healthproblems to the inhabitants, especially during the summer season. The wind forecast is anecessity for navigation in the estuary.
