Anantapur district lies in the southwestern part of Andhra Pradesh State between
13 0 -14’ and 15 0 -14’ North latitudes and 76 0 -26’ East longigudes. It forms part of the northern
extremity of the Karnataka Plateau and slopes from south to north. It is the southernmost
district in Rayalaseema region in Andhra Pradesh and is bounded on the east and north by
the Cuddapah and the Kurnool districts respectively, on the south by the Chittoor district,
and on the southwestern and western side by Karnataka State. Its general elevation towards
the sourth is about 670m while it gradually declines to about 305m at Gooty in the north and
275m at Tadipatri in the northeast. The eastern side towards the Cuddapah district is
particularly hilly. The Erramalais flank the northern frontiers of the district.
1.2 CLIMATE
The district lying off the coast does not enjoy the full benefit of the northeast
monsoon and being cut-off by the high Western Ghats, the rainfall from the southwest
monsoon is also curtailed. Thus, the district is partly deprived of both the monsoons and
subjected to recurrent droughts and partly famines.
1.3 RAINFALL
The normal rainfall of the district in 541mm which is lowest next to Jaisalmar in
Rajasthan.
The average precipitation in the district is 521 mm per annum (see A.P. Water
vision Vol-2), spread over four seasons as follows.
1. South-west monsoon period — 287mm (55.08%)
(June – September)
2. North-East monsoon period — 143mm (27.45%)
(October – November)
3. Cold weather period — 17mm(3.263%)
(December – February)

The analysis of weekly rainfall of the district indicates the probability of weekly
rainfall of over 20mm is highest in weeks 38 and 39 but even then, the incidence is only 50
per cent of the normal rainfall days. In 47 weeks, out of 52 weeks, the probability of atleast
10mm of rainfall is less than 50 per cent. In contrast, there is a 20 per cent probability, of
