Weather in São Paulo in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 25.4 °C, lows 16.2 °C, and rain falls on 13 days — nothing in the month is working against you.

April ranks 6 of 12 in São Paulo: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 13 days, 2 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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 32.1 °C and the coldest night fell to 8.9 °C, and the wettest single day dropped 41 mm — roughly 49% of the month's rain in one day.

April is moderately variable: 4 mm in the driest year against 150 mm in the wettest, around an average of 84 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 7.4 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 April sits in the year

Temperatures hold steady either side: 26.7 °C in March, 25.4 here, 22.8 in May. Nothing about the timing within the month matters much. Rain has already shifted: 7 days fewer than March had.

Daylight in April

11.6 hours of daylight, losing 0.6 hours across the month. That is between São Paulo's extremes of 13.6 and 10.7 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 16.8 °C between the year's warmest afternoons and coldest nights. At 769 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

Shoulder. The value months — prices ease off and you get the place closer to itself. April is the value pick for São Paulo: it scores within 11 points of August without carrying August's prices.

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

April in São Paulo versus nearby

If São Paulo is one option among several, the nearby comparison is worth making. Curitiba is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Rio de Janeiro is close enough to be a coin toss — 2.1 °C warmer, 1 day more rain.

So: April works, with August the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
