Weather in Curitiba in July

A good month. July is a solid month to be in Curitiba. Highs average 19.2 °C, lows 9.2 °C, and rain falls on 10 days — nothing in the month is working against you.

July ranks 2 of 12 in Curitiba. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 10 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average July reaches 30 °C. Across the twenty years measured, the hottest July day reached 27.1 °C and the coldest night fell to -3.8 °C, and the wettest single day dropped 52 mm — roughly 54% of the month's rain in one day.

July is moderately variable: 12 mm in the driest year against 281 mm in the wettest, around an average of 97 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 3.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 19.2 °C in June, 19.2 here, 21.1 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Curitiba's year — 10.7 hours of daylight against 13.7 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

Despite being inland, the year stays fairly even: 17.3 °C between the year's warmest afternoons and coldest nights. At 924 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, June is the trade worth considering — 7 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Curitiba versus nearby

If Curitiba is one option among several, the nearby comparison is worth making. São Paulo is a better bet in July — 3.3 °C warmer, 3 days less rain. Porto Alegre is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: July is effectively as good as it gets here — 6 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
