for the re-election of the President well as for the popular election of the Mayor of Buenos Aires, hitherto an appointed post. The Kheyvis nightclub fire of 20 December 1993 in Olivos was the deadliest such tragedy in Argentina up to that time. Olivos was selected as a stop along the Tren de la Costa tourist railway upon the line's opening in 1994. Geography Olivos is located on the western bank of the Rio de la Plata, the world's widest river. The river is approximately wide at Olivos, and as such, Uruguay is not visible from ground level. However, Olivos (and this entire region of the Rio) do not have sandy beaches; the shoreline is relatively rocky. Comparable shorelines include those of the Great Lakes in North America. The city's topography is relatively flat. However, there are some ridges by the river towards the north, in the La Lucila neighbourhood. The city is located about north of Buenos Aires, of which it is effectively a suburb, and south of Rosario. Montevideo , capital of Uruguay is due east of Olivos, across the river. Climate Olivos has an oceanic climate (Cfb). The city has comfortably warm summers but cool winters. Temperatures are noticeably more moderate than in places further inland, or even in nearby Buenos Aires, due to the lack of an urban heat island. Rainfall is fairly consistent throughout the year.
