Tissamaharama's weather in July indicates an average high-temperature of a still tropical 30.7°C (87.3°F), nearly consistent with the 30.6°C (87.1°F) of June. A mean low-temperature of 26.3°C (79.3°F) is anticipated during the month of July, a slight step down from the daytime high.

Heat index

The heat index value for July is evaluated at a torrid 38°C (100.4°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
