For instance, during the new moon phase, when the moon is not visible from Earth, the moonrise and moonset times are approximately the same as sunrise and sunset. As the moon progresses through its phases, its rise and set times gradually shift. During the full moon phase, when the entire face of the moon is illuminated by sunlight, the moon rises around sunset and sets around sunrise.
Moon Phases in Houston
Houston experiences all of the major moon phases throughout the year, including the new moon, crescent moon, first quarter moon, waxing gibbous moon, full moon, waning gibbous moon, third quarter moon, and waning crescent moon. Each phase lasts approximately 2-3 days, and the entire cycle from new moon to full moon and back to new moon takes about 29.5 days.
The appearance of the moon changes dramatically during the different phases. During the new moon phase, the moon is not visible from Earth. As the moon waxes, meaning it becomes increasingly illuminated, it appears as a thin crescent in the sky. The first quarter moon is half illuminated, and the waxing gibbous moon appears as a more than half-lit circle. The full moon is completely illuminated, and the waning gibbous moon gradually loses its illumination. The third quarter moon is half illuminated, and the waning crescent moon appears as a thin crescent in the sky before disappearing entirely during the new moon phase.
Seasonal Variation in Humidity
Houston experiences fluctuating humidity levels throughout the year. During the hot and humid summer months, the average relative humidity ranges from 75% to 90%, making the air feel muggy and uncomfortable. High humidity levels can cause heatstroke, heat exhaustion, and other heat-related illnesses.
