Weather shifts through genuine seasons here, from January's cool stretch to May's warmth, with rain a little heavier around November and lighter around February — real variation, but nothing as sharp as a true monsoon or Mediterranean dry season. In February, expect highs around 32°C with rain on roughly 15 days of the month.
