July is typically the coldest month in Buenos Aires, often featuring at least 1-2 particularly cold weeks. Based on my experience, evenings, nights, and early mornings can be especially chilly, with average temperatures ranging from 5°C (41°F) to 13°C (55°F). Additionally, it gets darker earlier, around 6 PM.

If you are planning a trip to Buenos Aires during this month, packing warmer clothes is essential. A warm jacket, scarf, and sweaters will be necessary. If you tend to feel the cold more, consider bringing a warm hat and gloves as well.

An interesting fact about Buenos Aires weather in July is that it actually snowed for one day in July 2007. This was a very rare occurrence but demonstrates that Buenos Aires can experience cold snaps during this month.

Here are some tips to help you stay comfortable during your visit to Buenos Aires in July:

• Clothing: Wear layers to stay warm, especially in the evenings and early mornings. A warm jacket, scarf, sweater, and possibly a hat and gloves if you are sensitive to the cold.
• Daylight: Plan your outdoor activities accordingly, as it gets dark earlier around 6 PM.
• Snow: While snow is a rare occurrence, be prepared for cold snaps.

Buenos Aires has a popular coffee culture, with many coffee houses—old, new, and bohemian—providing warm, inviting environments to escape the cold and enjoy a hot drink.
