Climate & Sowing Windows in Rohtas
Rohtas receives about 912 mm of rain in an average year, 86% of it in June-September. The wettest month is July (265 mm). Days are hottest in May (average high 43°C) and nights coolest in January (average low 9°C).
- Rain typically first crosses 100 mm a month in June, the usual cue for kharif sowing here.
- 86% of the year's rain falls in June-September, so rabi and summer crops need assured irrigation.
- Winter nights average about 9°C, cool enough for rabi crops such as wheat, mustard, gram and potato.
- March days already average 35°C, so late-sown wheat risks heat stress at grain filling. Sowing by mid-November is safer.
- May days average 43°C, so summer (zaid) crops and young orchards need frequent irrigation and mulching.
