The objective of this study was to compare the weather data obtained from both conventional (CWS) and automatic (AWS) weather stations, in Jaboticabal, SP, Brazil (latitude: 21º14'05" S, longitude: 48º17'09" W and altitude: 613,68m), from July 1997 to June 2002. Daily data were collected and analyzed statistically by regression analysis. The results showed a good relationship between CWS and AWS, specially for air mean temperature, minimum temperature, maximum temperature and rainfall. Air humidity and atmospheric pressure showed the highest errors, respectively equal to 5,69% and 3,64 hPa. Wind velocity at 2m did not show good precision and accuracy because its estimation for CWS.
