Climate & Sowing Windows in Tirunelveli
Tirunelveli receives about 1293 mm of rain in an average year, 36% of it in June-September. The wettest month is October (246 mm). Days are hottest in March (average high 35°C) and nights coolest in January (average low 19°C).
- Unusually for India, 41% of Tirunelveli's rain falls in October-December from the north-east monsoon, so the main cropping calendar follows that season rather than June sowing.
- January days still average 29°C, too warm for wheat to yield well; the cool season suits warm-tolerant pulses, oilseeds and vegetables better.
