Chilpancingo, located in the central region of Mexico, experiences a tropical savanna climate characterized by distinct wet and dry seasons. During the wet season, from May to October, heavy rainfall is common, with average monthly precipitation exceeding 100 millimeters (4 inches). This rainfall is primarily brought by the summer monsoon winds that deliver moisture from the Pacific Ocean and the Gulf of Mexico. The city’s wettest month is typically September, with average precipitation reaching around 200 millimeters (8 inches).

In contrast, the dry season in Chilpancingo lasts from November to April and is characterized by significantly less precipitation. During this period, monthly precipitation drops below 50 millimeters (2 inches), with some months receiving virtually no rainfall. The lowest precipitation typically occurs in March, with average rainfall below 10 millimeters (0.4 inches). The dry season is influenced by the northward migration of the Intertropical Convergence Zone (ITCZ), which shifts the rain-bearing clouds away from the region.

Annual Rainfall Patterns

Chilpancingo, Mexico, experiences distinct annual rainfall patterns. From May to October, the city is under the influence of the North American Monsoon, which brings abundant rainfall.

Moon Phase and Timing:

The moon’s appearance in Chilpancingo, Mexico, varies throughout the lunar cycle as it orbits Earth. The cycle takes approximately 29.5 days to complete, passing through eight distinct phases. The most prominent phases are the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. The timing of each phase can be predicted using astronomical charts or online moon phase calculators.

Moonrise and Moonset:

The moonrise and moonset times in Chilpancingo also vary depending on the lunar phase. The new moon, which occurs when the moon is aligned between the Earth and the sun, is not visible from Earth. As the moon waxes, its rise time shifts earlier in the evening, reaching the highest point in the sky at the full moon phase. During this phase, the moon is visible for most of the night. After the full moon, the moonset time shifts earlier in the morning as the moon wanes. The moonrise and moonset times can be found in local weather reports or astronomical data for a specific location and date.

Seasonal Variations in Humidity

Chilpancingo experiences significant seasonal variations in humidity levels. During the dry season, which typically lasts from November to April, humidity is generally low, ranging from 30% to 50%. This is due to the influence of prevailing northeasterly trade winds that bring dry air from the Gulf of Mexico.

However, during the wet season, which extends from May to October, humidity levels rise substantially. The influx of moisture-laden southerly winds from the Pacific Ocean leads to higher humidity, typically ranging from 60% to 80%. The peak humidity occurs during the months of July and August, when the city experiences frequent thunderstorms and heavy rainfall.

Diurnal Variations in Humidity

Humidity levels in Chilpancingo also exhibit diurnal variations. Typically, humidity is highest in the early morning hours, when temperatures are cooler and the air is more saturated with moisture. As the day progresses and temperatures rise, humidity levels gradually decrease. However, during the late evening and night, humidity may increase again as temperatures drop and the air becomes more stable.

The diurnal variations in humidity are influenced by several factors, including the evaporation of moisture from the ground, transpiration from plants, and the presence of clouds. During the day, the sun’s heat causes moisture to evaporate from the ground and plants, increasing humidity. However, as temperatures cool in the evening, evaporation and transpiration decrease, leading to a reduction in humidity.

Wind Patterns in Chilpancingo

Chilpancingo, the capital of the Mexican state of Guerrero, experiences distinct wind patterns throughout the year. During the dry season (October to May), the prevailing winds come from the north and northeast, bringing cool and dry air from the Sierra Madre Occidental mountains. These winds are known as “nortes” and can be strong and gusty, particularly in the early morning and evening.

During the wet season (June to September), the wind direction shifts as the Intertropical Convergence Zone (ITCZ) moves northward. The prevailing winds during this time come from the southwest and southeast, carrying moisture from the Pacific Ocean. These winds are often associated with heavy rainfall, thunderstorms, and occasional tropical cyclones. The wind speed is generally lower during the wet season compared to the dry season, but strong winds can still occur during storms.
