Temperature

Sastre witnesses the warmest weather in January, with temperatures averaging a high of 33.9°C (93°F) and a low of 20.3°C (68.5°F).

Heat index

For most parts of January, the heat index is evaluated at a torrid 38°C (100.4°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Shun overexposure. Protection from sun ravages is indispensable. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
