Weather in January
Temperature
The average high-temperature in January, at a still hot 31.1°C (88°F), reveals a modest deviation from December's 30.5°C (86.9°F). San Felipe, during the month of January, experiences an average low-temperature of 19.6°C (67.3°F).Heat index
For January, the heat index is calculated to be a very hot 35°C (95°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
Humidity
January through March, with an average relative humidity of 59%, are the least humid months.Rainfall
January and February are months with the least rain when the rain falls for 6.3 days and typically aggregates up to 11mm (0.43") of rain.Daylight

Sunshine
In San Felipe, the average sunshine in January is 8.3h.UV index
The months with the lowest UV index are January, May, June, August through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.Note: The maximum daily UV index of 6 in January converts into the following recommendations:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
