AB Gravity tide records from El Hierro, Tenerife and Lanzarote Islands (Canarian Archipelago) have beenanalyzed and compared to the theoretical body tide model (DDW) of Dehant el al. (1999). The use ofmore stringent criterion of tidal analysis using VAV program allowed us to reduce the error bars by afactor of two of the gravimetric factors at Tenerife and Lanzarote compared with previous publishedvalues. Also, the calibration values have been revisited at those sites. Precise ocean tide loading (OTL)corrections based on up-to-date global ocean models and improved regional ocean model have beenobtained for the main tidal harmonics O1, K1, M2, S2.We also point out the importance of using the mostaccurate coastline definition for OTL calculations in the Canaries. The remaining observational errorsdepend on the accuracy of the calibration of the gravimeters and/or on the length of the observed dataseries. Finally, the comparison of the tidal observations with the theoretical body tide models has beendone with an accuracy level of 0.1% at El Hierro, 0.4% at Tenerife and 0.5% at Lanzarote.
