Weather in January
Temperature
The start of January marks an average high-temperature of a still warm 29.8°C (85.6°F), hardly distinguishable from the conditions in December. Throughout January, Zancudo experiences a low-temperature average of 20.5°C (68.9°F).Heat index
For January, the heat index is calculated to be a very hot 36°C (96.8°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
