What to expect in the worst months
October. Highs in the 32°C range are tolerable in the shade but draining if you're walking all day. 20 rain days out of 31 means roughly 65% of days see measurable rainfall — plan flexible indoor backups for every outdoor day.
September. Daytime highs averaging 33°C / 92°F mean outdoor sightseeing between roughly 11 a.m. and 4 p.m. becomes uncomfortable — locals retreat indoors and many smaller shops close in the afternoon.
January. 24 rain days out of 31 means roughly 77% of days see measurable rainfall — plan flexible indoor backups for every outdoor day.
