SB 10.18.2
vraje vikridator evam
gopala-cchadma-mayaya
grismo namartur abhavan
nati-preyañ charirinam
Translation:
While Krsna and Balarama were thus enjoying life in Vrndavana in the guise of ordinary cowherd boys, the summer season gradually appeared. This season is not very pleasing to embodied souls.
Purport:
In Chapter Eighteen, of Krsna, the Supreme Personality of Godhead, Srila Prabhupada comments as follows: “The summer season in India is not very much welcomed because of the excessive heat, but in Vrndavana everyone was pleased because summer there appeared just like spring.”
