Argentina · 25.60°S 54.57°W · monthly climate normals, judged against the Warm preset (mean 14–24 °C57–75 °F, dry or showers)
No month in Iguazú fits the Warm preset (mean 14–24 °C57–75 °F, dry or showers) — the rain never lets up. The table below shows which holiday types do fit.
Rain falls year-round, 104–192 mm4.1–7.6 in a month, so there is no dry season to aim for; July is the driest month and October the wettest. January is the hottest month at 26 °C79 °F and July the coldest at 16 °C61 °F.
Figures are 30-year monthly averages (WorldClim 2.1 monthly normals 1970–2000) for the 0.25° grid cell at -25.60, -54.57 — a climate guide, not a forecast.
Pick the weather you like and every month is judged against it — temperature above the month names, rain below.

Reading the chart. Gold is good: the month fits what you picked. Any other colour names the reason it doesn't — the temperature bar can be too cold or too hot, the rain bar too dry, too rainy or monsoon. A faded gold bar is a half that fits while the other half fails; a gold month name means both fit.
What the verdicts mean. Temperature is the monthly mean, judged against the preset's band (mean 14–24 °C57–75 °F for Warm). Rain is judged by each month's class within Iguazú's own year rather than raw millimetres: dry under 60 mm2.4 in, showers 60–100 mm2.4–3.9 in, rainy from 100 mm3.9 in and 35 % of the wettest month. Too rainy is a rainy-season month the preset doesn't allow. Monsoon is the heaviest kind of rainy season — 180 mm7.1 in or more (120 mm4.7 in near the yearly peak) in a climate whose wettest month is at least three times its driest — so every monsoon month is rainy season too; the label says which kind. Full rules on the method page.
