Rayalaseema · Deccan Inland Plateau
Terrain and eco-zones
Semi-arid, and the driest part of the Telugu country by a wide margin. Anantapur averages around 550 mm and is routinely described as the most drought-prone district in India after Jaisalmer; Kurnool and Kadapa run 600–750 mm. The region sits between two monsoon systems and is failed by both — it is in the rain shadow of the Western Ghats in June to September, and too far inland to get the full north-east monsoon in October and November. Summer maxima reach 42–45 °C, and the diurnal range is wide because the air is dry and the rock radiates at night.

Rivers and waters
Through the year
| Season | Months | Typical | What it is like |
|---|---|---|---|
| Summer | March–June | 28–45 °C | Tanks and open wells empty. Ragi java and ambali replace cooked breakfast, and the drinking-water tanker is a normal feature of village life in the Anantapur belt. |
| South-west monsoon | June–September | 25–35 °C | Weak and unreliable — the region is in the Ghats' shadow. Groundnut is sown against this rain and the crop's success or failure is decided in a fortnight. |
| North-east monsoon | October–November | 22–32 °C | The Kadapa basin and the Tirupati slope get more of this than the west does. Cyclone remnants crossing from the Bay occasionally deliver a year's rain in two days. |
| Winter | December–February | 15–31 °C | Dry, mild and the season for everything — the fort and temple landscape, the ghat climb at Tirumala, and the jatara and Brahmotsavam calendar in the smaller shrines. |
Best time to visitNovember to February. Gandikota and Belum are unpleasant from March onward and best in the fortnight after heavy rain; Tirumala is crowded year-round but at its worst during Brahmotsavam in September–October, at Vaikunta Ekadasi and through the summer school holidays. Lepakshi's murals need late-morning light.
