During the New Moon phase, the Moon is not visible from Earth because it is positioned between the Earth and the Sun. As the Moon moves around the Earth, it gradually becomes illuminated by sunlight, leading to the Waxing Crescent, First Quarter, and Waxing Gibbous phases. The Full Moon phase occurs when the entire Moon is visible and illuminated. After reaching the Full Moon, the Moon begins to decrease in illumination, progressing through the Waning Gibbous, Third Quarter, and Waning Crescent phases before returning to the New Moon phase.

The exact time of Moonrise and Moonset depends on factors such as the Moon’s phase, the Earth’s rotation, and the observer’s location within Guelph. During the New Moon phase, Moonrise and Moonset occur simultaneously, as the Moon is not visible from Earth. As the Moon progresses through its phases, the time of Moonrise and Moonset gradually shifts, with Moonrise occurring earlier and Moonset later during the Waxing phases and vice versa during the Waning phases.

Seasonal Humidity Variations

Guelph, Canada experiences significant fluctuations in humidity levels throughout the year. During the cold winter months (December to February), the air remains relatively dry due to low temperatures and reduced precipitation. Relative humidity typically ranges between 50% to 70%, creating a comfortable indoor environment.

By summer (June to August), the city experiences its most humid period. Relative humidity often exceeds 80%, resulting in a muggy and oppressive atmosphere.

Relative Humidity and Health

The level of humidity in the air can have a significant impact on human comfort and health. Excessive humidity can promote the growth of mold and mildew, which can cause respiratory problems for sensitive individuals. During periods of high humidity, it is important to keep indoor air dry and well-ventilated to prevent the buildup of moisture. Conversely, low humidity levels can also be uncomfortable, leading to dry skin, eyes, and nasal passages. Maintaining an optimal relative humidity level between 40% to 60% is recommended for both comfort and health.
