ResumoAltitude and temperature relationships are especially important for the tropical and subtropical regions, where an altitudinal increase of some hundred meters changes the environmental conditions and leads to sensitive adaptation of the biota. Average air temperature changes with altitude, latitude and longitude, as well as each location, all have specific thermal gradients related to these parameters. In this work, the State of Parana was delimited into homogeneous climate sub-regions and analyses were made of correlations between average temperature in January, July and the annual average, along with the altitudes of their respective groups. The correlation between altitude and average January temperature was, in general, stronger than that for July. Straight lines were obtained or the higher correlation coefficients their coefficients of determination with simple linear regression. The average thermal gradient obtained for the set of all stations of the state, excluding the coastline, was 1oC / 126 m, with this gradient ranging from 124 to 141 m to the southwest and north, respectively. Average thermal gradients were obtained as a function of latitude and longitude. The altitude, latitude and longitude, in that order, almost completely determine the average temperature of the air. Key-words: Altitudinal thermal gradient. Agroclimatic zoning. Climate. Parana temperature. Linear regression. Parana climate.
