Lima is giving visitors a very different kind of winter this year. While August is usually one of the coolest and grayest months in Peru's capital, temperatures are rising significantly this week, bringing sunny days that feel much more like beach weather. The unusual conditions are linked to the effects of the El Niño climate phenomenon, which has been influencing weather patterns along Peru's coast.
According to Peru's National Meteorology and Hydrology Service (Senamhi), Lima and other coastal regions will experience a period of unusually high temperatures on August 12 and 13. In parts of Lima and Callao, temperatures could reach around 36°C (97°F), while several other regions along the Peruvian coast are also expected to see warmer conditions.
For travelers arriving in Lima, this means it may be worth packing a little differently than you would normally expect for a Peruvian winter. Light clothing, sunglasses, a hat, and sunscreen can be useful during the day, especially if you plan to spend time outdoors or explore the city on foot. Staying hydrated and taking some shade during the warmest hours is also a good idea.
Temperatures can still feel cooler at night, so having a light jacket is useful as well. Lima's weather can change quickly, and conditions are very different across Peru, particularly if your trip also includes destinations in the Andes or the Amazon. Checking the forecast before traveling can help you pack for the actual weather you will encounter.
For now, though, Lima's winter is looking a lot sunnier than usual, giving travelers an unexpected taste of summer in the middle of August.
