January weather forecast
Hua Hin, Thailand

Starting off the year, Hua Hin is greeted with a warm climate and relatively dry days. The city experiences its second driest month, only receiving 12mm (0.47") of rain, a notable decrease from the rainier months preceding it. Sun-seekers will find delight in the ample daylight hours and higher UV index, ensuring a great surplus of sunshine. The town's coastal location provides relief from the heat, with the soothing ocean breeze bringing balance to the warm afternoons. As the first month of the year progresses, a gradual increase in temperature is likely to be noted.

Temperature

The start of January marks an average high-temperature of a still warm 29.9°C (85.8°F), hardly distinguishable from the conditions in December. Throughout the nights in January, Hua Hin experiences an average low-temperature of 22.2°C (72°F).

Heat index

January's mean heat index is computed to be a sweltering 35°C (95°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
The heat index's values are generally associated with conditions in 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 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and 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. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Note: The UV index of 10 during January translates into the following guidance:
Always take safety measures. The skin and eyes are at risk if left exposed. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Applying and reapplying a broad-spectrum sunscreen with a minimum SPF 30 after every two hours, outdoor workout, or swim is recommended. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
