Weather in May

May, the last month of the spring in Marin, is also a hot month, with an average temperature ranging between max 31°C (87.8°F) and min 20.2°C (68.4°F).

Temperature

The onset of May brings with it an average high-temperature of a still tropical 31°C (87.8°F), showing a negligible variation from the month before. In the month of May, Marin witnesses a consistent average low-temperature of 20.2°C (68.4°F).

Heat index

For May, the heat index is computed to be a sweltering 39°C (102.2°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In Marin, the average relative humidity in May is 74%.

Rainfall

May is the month with the most rainfall. Rain falls for 22.8 days and accumulates 107mm (4.21") of precipitation.

Sunshine

In May, the average sunshine is 10.9h.

UV index

January through May, September through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for average individuals.
Note: In May, the maximum UV index of 6 suggests this advice:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
