Weather in January
Temperature
Zastron's temperatures tend to reach their peak averages in January, with a high of 28.8°C (83.8°F) and a low of 16.3°C (61.3°F).Heat index
In January, the heat index is calculated to be 29°C (84.2°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
