As such meteorologists in India and especially in TN never refer the word 'AGNI NATCHATHIRAM'. Perhaps ancient Tamil people in their climatology, might have classified this period [in the month of May]as hot summer period and named it as 'AGNI Natchathiram. There has been no reference in meteorological glossary, since hottest days may extend in June too.
But the wisdom of the ancient Tamils has to be considered.

    What are "DOG DAYS"?
    Dog Days are days of extreme heat, sweat, water and electricity shortage..

  3. Sun Sidereal longitude from 20°00’ to Sidereal longitude 13 °20’ (43°20’) days are called Agni Nakshtra – Kathiri. This year falls on 4th May 2012 and ends on 29th May 2012.

    The seasons are caused by a combination of things. The Earth is tilted (23.5 Degree) as it moves around the sun.

    Direct sunlight produces more heat than the indirect light.
    Direct sunlight days are called as summer where the heat will be maximum which are known as “Agni Nakstra – Kathiri ”
