Weather in January
Temperature
The transition into January notes an average high-temperature of a still moderately hot 27.5°C (81.5°F), revealing a mild distinction from the 25.7°C (78.3°F) in December. An average temperature of 19.5°C (67.1°F) marks the nights in Cottesloe in January.Heat index
In January, the heat index is calculated to be 29°C (84.2°F). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', 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. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
