Buenos Aires weather by month

The climate tool uses the complete SMN 1991 to 2020 normals for Buenos Aires Observatorio, WMO station 87585. The station sits at 25 m above sea level. Its monthly highs, lows, means, rainfall and rain-day counts come from the same source. The values describe a long-term baseline, rather than today's conditions.¹

Use Buenos Aires neighborhoods to plan the apartment location. Then use the climate table to inspect cooling, heating and outdoor routes for the season you will arrive. The moving checklist keeps those checks alongside the lease and arrival arrangements.

January has the highest average high at 30.1°C (86.2°F). July has the lowest average high at 15.5°C (59.9°F). This 14.6°C (26.3°F) difference is why a winter apartment inspection cannot stand in for a summer cooling check. Ask about the actual equipment and test it before signing.¹

January has the highest average rain volume at 134.4 mm (5.3 in), while October has the most qualifying rain days at 7.9. June has the lowest rain volume at 61.5 mm (2.4 in). Buenos Aires therefore has a wetter summer pattern, but no month in this table supports a rain-free season.¹

Take rain gear on apartment-viewing days and check the drainage around the entrance. A normal rain-day count does not establish the flood risk of an individual property. Use the city's live alerts and ask the building manager about prior water entry. The rent guide covers the wider inspection.²

The seasons run opposite to North America and Europe. A December arrival is a summer arrival. A July arrival is a winter arrival. Match the apartment inspection and packing to Buenos Aires conditions, rather than the season where you depart. For school timing, use the families guide before choosing a date.

March is our first weather-led recommendation for an apartment search. Its average high is 27.0°C (80.6°F), with 6.7 rain days. October is the runner-up, with a 22.6°C (72.7°F) average high but more rain days at 7.9. The school calendar or visa timing can outweigh this comfort judgment.¹

Read the moving checklist and Argentina visas before organizing the move around weather. A climate preference cannot establish entry permission or a school place. Confirm those fixed dates first, then choose a comfortable viewing week.

• Summer coolingBring light clothing and inspect how the apartment cools during the afternoon. January highs average 30.1°C (86.2°F).
• Winter layersPack a warm jacket and layers for evenings. July lows average 7.5°C (45.5°F).
• Rain gearKeep a compact umbrella or rain jacket accessible in every season. No month is rain-free in the normals.
• Comfortable shoesTest the station and grocery walks in the footwear you will use for daily errands.
• Seasonal desk comfortCheck sun glare and airflow for the room where you expect to work.

For a remote-work move, inspect the desk room at its normal work hour. Cooling, heating and street noise affect calls as well as sleep. Compare actual utility and equipment arrangements through the cost of living guide, rather than assuming the advertised rent includes comfortable indoor conditions.

Averages can hide heat, cold and intense rain. SMN publishes separate extreme-temperature alerts because the expected highs and lows can create health risks. Check the live alert category rather than assuming a 30-year average describes your arrival week. Use the healthcare guide for medical planning.⁴

Buenos Aires includes intense rain and flooding from sudestada conditions in its emergency planning. The city's storm guidance routes public emergencies to 103. Follow official warnings and avoid flooded streets. The monthly rain table cannot show whether a specific basement, entrance or route will flood.^2,3

1. 1

   Check the official alert

   Use SMN's live warning and the city's instructions before leaving for viewings or airport travel.

2. 2

   Inspect the property history

   Ask the building manager about water entry, drainage and any prior storm repairs.

3. 3

   Change the route during flooding

   Avoid flooded streets and follow the city's warning. Do not treat a normal route map as a live flood assessment.

4. 4

   Keep essential documents accessible

   Follow the city's severe-alert advice and keep medicines, documents and a charged phone accessible.

Sudestada

A southeastern wind event associated with rising estuary water and potential flooding in the city's emergency planning.

Alerta meteorológica

An official weather warning. Check its live severity and the local instructions.

Normal climatológica

A long-term climate average, rather than a forecast for a particular day.

A mild daytime winter average does not establish a warm apartment. Test heating and hot water, inspect window seals and ask how the cooling works in the bedroom. The normals show a seasonal need for both. Ask for actual equipment and utility terms before treating a furnished apartment as ready for every season.¹

This page does not have a verified current annual air-pollution figure for Buenos Aires. It therefore does not score the city as clean or publish an unsupported asthma comparison.
