November, the last month of the post-monsoon autumn in
Mangaluru, is also a hot month, with an average temperature varying between 32.3°C (90.1°F) and 22.4°C (72.3°F).
The ideal sea water temperature of 29.2°C (84.6°F) and only 3.6 rainfall days, with 71mm (2.8") of accumulated rainfall, makes November the best time for swimming and other water activities.
Temperature
Mangaluru's average high-temperature marks a still hot 32.3°C (90.1°F) with the advent of November, closely mirroring that of the preceding month. During the month of November, Mangaluru experiences a steady low-temperature average of 22.4°C (72.3°F).
Heat index
November's mean heat index is appraised at a blisteringly hot 42°C (107.6°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
In reference to the heat index, it's for places in shade and with a slight wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. As body temperatures escalate without effective heat release, one might face dehydration threats.

Note: A daily high UV index of 10 in November leads to these guidelines:
Always take precautions; unprotected eyes and skin can be damaged rapidly. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance. Even when the sky is cloudy, apply generously and frequently reapply a sunscreen with SPF 30 or more, especially post every swim or outdoor exercise. Attention! UV radiation is markedly stronger with water and sand reflections.
