Conteúdo:	The area of interest for this study lies in the Western part of the Amazon. Monthly and annual meteorological data from 12 places were used, with daily data from eight rain gauges and daily rainfall intensity records. Data were presented from tests of water infiltration into the soil performed in the region. The results showed that the Northwest part of the region was the rainiest, attaining annual means of 3,333 mm at Iauaretê. In the Southern part, beginning at 5°S, the mean values reached 1,952 mm, at Rio Branco. Mean annual rainfalls ranged from 2,500 mm to 2,200 mm, in the region. The lowest pluvial total was 1,365 mm, which occurred at Parintins in 1983, and may be associated to the effects of a strong El Niño (82-83). In years when La Niña was strong, rainfalls were above the average and when El Niño was strong, they were below the average. The rainiest period was from December to April with means above 160 mm and the least rainy was from May to September, August being the month with the lowest rainfall. Close to Humaitá, annual rainfalls were less than 2,000 mm.
