October weather forecast
Campeche, Mexico

October sees a welcomed change as the rainy season begins to fade away. While temperature remains relatively high, residents and visitors are relieved as daily sun hours increase. Though still a part of the rainy season, a noticeable decrease in rainfall occurs. The weather pattern in October lays the groundwork for a even drier November.

Temperature

Campeche's weather, upon October's arrival, documents an average high-temperature of a still hot 30.5°C (86.9°F), nearly identical to the prior month. An average low-temperature of 23.3°C (73.9°F) is recorded during the nights in October.

Heat index

Throughout October, the heat index is computed to be a torrid 39°C (102.2°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The months with the highest humidity are September and October, with an average relative humidity of 78%.

Rainfall

In Campeche, in October, during 16.3 rainfall days, 83mm (3.27") of precipitation is typically accumulated. Throughout the year, there are 149.4 rainfall days, and 548mm (21.57") of precipitation is accumulated.

Sea temperature

In Campeche, the average seawater temperature in October is 28.6°C (83.5°F).
Note: Engaging in water activities, such as swimming or diving, in temperatures from 25°C (77°F) to 29°C (84.2°F) is very pleasurable for extended periods, without any discomfort.

Daylight

In Campeche, the average length of the day in October is 11h and 41min.
On the first day of the month, sunrise is at 5:53 am and sunset at 5:49 pm. On the last day of October, sunrise is at 6:03 am and sunset at 5:28 pm CST.

Sunshine

In October, the average sunshine is 8.3h.

UV index

February through October, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: In October, the maximum UV index of 7 suggests this advice:
Fend off overexposure. Sun protection is vital. 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. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Attention! The reflection of both water and sand can increase the intensity of UV rays.
