Weather in Salta in April
Argentina · 20-year averages, April
Prime time. April is about as good as Salta gets. Highs average 27.7 °C, lows 15.8 °C, and rain falls on 8 days — nothing in the month is working against you.
April ranks 6 of 12 in Salta: past the worst of the year but short of June, which is the month to book if the dates are open.
Rain on 8 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
Averages flatten a month, and this one hides a few things: 8 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest April day reached 37 °C and the coldest night fell to 3.5 °C, and the wettest single day dropped 48 mm — roughly 84% of the month's rain in one day.
April is moderately variable: 9 mm in the driest year against 172 mm in the wettest, around an average of 57 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 is unremarkable at 73%.
How April sits in the year
Temperatures hold steady either side: 29 °C in March, 27.7 here, 25.9 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 5 days less of it, so pushing the dates later buys drier weather.
Daylight in April
11.5 hours of daylight, losing 0.7 hours across the month. That is between Salta's extremes of 13.7 and 10.6 hours, so days are long enough not to constrain the plan.
An inland climate
Despite being inland, the year stays fairly even: 21.9 °C between the year's warmest afternoons and coldest nights. At 1054 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.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
April in Salta versus nearby
If Salta is one option among several, the nearby comparison is worth making. San Miguel de Tucumán is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Antofagasta is a better bet in April — 7.9 °C cooler, 8 days less rain.
So: April works, with June the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
