Less a stay, more a same-day stop — the passport stamps show entry and exit at KL International dated the exact same day, on the way back to India as part of the same Indonesia family trip.
June–August or December–February is the two relatively drier stretches in an otherwise year-round tropical climate. For a same-day transit like this one, timing barely matters — KL International runs the same regardless of season.
That a same-day transit stop needed its own visa research at all. This wasn't the actual trip — it was a connection, a few hours between flights — and yet it still generated its own small paper trail (entry conditions for West Malaysia and Sabah, the family's later $21.50 eVisas processed through a UK-based agent rather than Malaysia's own portal). Even the in-between parts of a trip turn out to have logistics worth documenting.
The family's $21.50 e-visas here went through a UK-based agent rather than Malaysia's own system — likely paying a markup for the same visa.
If you're just transiting through KL International, you may not need a visa for that stop specifically.
