The central municipality (distrito) of San Ramón covers an area of 1.29 km2 (0.50 sq mi)[1] and has a population of 10,710.

However, cities are no longer a valid administrative division in Costa Rica, by municipal codex law 7794 of April 30, 1998.

One route runs out of the north of town directly to the popular Costa Rican destination of Volcan Arenal, and the Pan-American Highway runs just south of the city's southern edge granting easy access to all other north-south points in the country, as well as linking San Ramón to the Americas.

Diurnal periods are very predictable due to Costa Rica's latitude: The sun rises in San Ramon by about 05:45 and sets at 18:30 with very little variation throughout the year.

As the morning sun rises, air which is already moist due to a certain amount of orographic lift being added by the Pacific Ocean, is further loaded by evapotranspiration wherein water drawn from the ground by plants and trees is transpired into the atmosphere.
