The climate of Tiruchirappalli (or Trichinopoly, Tiruchi or Trichy) is
from September to November. In the other months, the rains are quite irregular, and are generally not abundant. Temperatures are high all year round, and are higher than on the coast, although they drop a bit from November to January.
We are in the south-eastern side of India, where the summer monsoon does not arrive because it is hindered by the Western Ghats, especially in the first period, in June and July, when the currents blow more directly from the west. Instead, the rains increase from August or September, when the currents from the east or north-east blow more and more often.
. Typically, cyclones occur from April to December, although the extreme south of India is normally affected only in November and December. In any case, since the sea is warm all year round, in theory they can also form from January to March, perhaps in light form (as tropical storms).
to visit Tiruchirappalli is from late December to late January, as it is the least hot within the dry season. In February and March, it is still the dry season, but it is very hot.
