The city lies within the temperate zone, characterized by warm, humid summers and relatively mild winters. Snowfall typically occurs from December to February, with an average annual accumulation of around 40 centimeters (16 inches). Nishio’s snowfall is influenced by the seasonal shifts in wind patterns and the proximity to the Sea of Japan.

Sunrise and Sunset Times in Nishio

The timing of sunrise and sunset in Nishio, Japan, varies throughout the year due to the Earth’s tilt and rotation. In summer, the sun rises earlier and sets later, providing longer daylight hours. During winter, the opposite occurs, resulting in shorter daylight hours with earlier sunsets and later sunrises. Specific sunrise and sunset times can be calculated using astronomical tables or online calculators based on the exact date and location.

Seasonal Variations in Sunlight

The amount of sunlight received in Nishio also varies seasonally. During summer, the sun is higher in the sky for longer periods, leading to more intense and prolonged sunlight exposure. This can result in higher temperatures, increased UV radiation, and a greater potential for sunburn and heat-related illnesses. In contrast, during winter, the sun is lower in the sky for shorter periods, resulting in less intense sunlight and a lower risk of sun exposure-related health concerns.

Phases of the Moon

The Moon’s appearance and position in the sky vary throughout the month as it orbits Earth. This cycle of changes is known as the phases of the Moon. In Nishio, Japan, the Moon’s phases can be observed clearly during periods of clear skies. During the new moon phase, the Moon is not visible from Earth as it is located between the Earth and the Sun. As the Moon moves around Earth, it appears as a crescent moon, gradually increasing in size and becoming a half-moon. The full moon phase occurs when the Moon is opposite the Sun in the sky, and its entire face is illuminated. After the full moon, the Moon’s illumination decreases, transitioning through the waning gibbous, waning crescent, and back to the new moon.

Moon Observation in Nishio

Nishio is located in a relatively flat area, surrounded by mountains. This topography provides excellent opportunities for observing the Moon. On clear nights, the Moon can be seen rising above the horizon, casting a soft glow over the city. The best time to observe the Moon in Nishio is during the spring and autumn months, when there is typically less cloud cover. The city is also home to several observatories, such as the Nishio City Astronomical Observatory, which offer guided tours and astronomy programs for the public. These observatories provide telescopes and expert guidance, allowing visitors to get a closer look at the Moon and other celestial bodies.

Annual Humidity Patterns

Nishio, Japan experiences moderate to high humidity levels throughout the year, influenced by its coastal location and proximity to the warm Kuroshio Current. The annual average relative humidity hovers around 70%, reaching its peak during the summer months. In July and August, humidity levels can exceed 80%, creating a sultry and uncomfortable atmosphere.

Conversely, the winter months bring drier conditions, with relative humidity dropping to around 60%. January and February typically see the lowest humidity levels of the year, offering a respite from the oppressive humidity experienced during the warmer seasons. Diurnal variations in humidity are also evident, with mornings and evenings exhibiting higher humidity levels than afternoons due to dew formation and reduced solar radiation.

Seasonal Wind Variations

Nishio, a city located in southern Aichi Prefecture, Japan, experiences notable seasonal variations in wind patterns. During the warm months (April to September), the prevailing wind direction is from the south or southeast. These winds carry warm, moist air from the Pacific Ocean, resulting in humid conditions and occasional thunderstorms. Conversely, during the colder months (October to March), the winds shift to the northwest or west. These winds originate from the continent and are typically drier and cooler, bringing occasional clear skies and crisp conditions.

Influence of Topography and Surrounding Water Bodies

The topography of Nishio and its proximity to the sea also influence local wind patterns. The Mikawa Bay to the south and the Tenryu River to the west create a funnel effect, channeling winds through the city. This effect is particularly pronounced during the spring and fall when the land warms or cools faster than the water bodies, creating pressure differences that generate strong winds. Additionally, the nearby coastal mountains contribute to wind turbulence, resulting in variable wind directions and speeds within the city.
