Due to its extreme latitude, Eureka, N. W. T. experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.

In the winter at Eureka, N. W. T. during 2024, the Sun is continuously below the horizon for 4.0 months, setting at 1:05 PM on October 20, and not rising again until 11:02 AM on February 21. As such, the sun is continuously below the horizon for the entire month of January.

Daylight saving time is observed at Eureka, N. W. T. during 2024, but it neither starts nor ends during January, so the entire month is in daylight saving time.

The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.

The figure below presents a compact representation of key lunar data for January 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy at Eureka, N. W. T. is essentially constant during January, remaining around 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed at Eureka, N. W. T. is essentially constant during January, remaining within 0.2 miles per hour of 7.3 miles per hour throughout.

For reference, on July 7, the windiest day of the year, the daily average wind speed is 8.1 miles per hour, while on September 20, the calmest day of the year, the daily average wind speed is 6.0 miles per hour.

The highest daily average wind speed during January is 7.5 miles per hour on January 27.

The hourly average wind direction at Eureka, N. W. T. throughout January is predominantly from the north, with a peak proportion of 47% on January 9.
