Washington is hot in July, often memorably so. For most of the month, the city’s average daily high temperature is 90. But Sunday was seven degrees above the District’s elevated average.

Perhaps all hot days are hot in their own way. Sunday’s heat, though obvious and apparent, seemed a bit more tolerable, a bit less insufferable, because it came unaccompanied by the unpleasant humidity of the two earlier days.

The heat index, a measure of the special torments presented by the combination of heat and humidity, remained in the 90s. Unlike Friday and Saturday, it made no forays above 100 degrees.

Dew points, which also express the extent and effect of humidity, also declined on Sunday, remaining in the low 60s.

In essence, that meant the day was not simultaneously scorching and steamy. The scorch could certainly be felt, but the frequently moist and vaporous sense of objectionable sultriness, that seemed largely absent.

On Friday, the dew point just before 3 p.m. was an oppressive — if not insufferable — 74. By Saturday at the same hour, it had declined to 70 degrees. That was a descent perhaps not universally acknowledged.

But on Sunday, the difference seemed marked, with a dew point of nine degrees less, at 61.

Such small distinctions make one summer’s day different from another. They prevent each day during a hot season from seeming to merge into the next, as only another unpleasantly torrid extension of what had come before.

But in the main, these have been hot days. On Friday, D.C. Mayor Muriel E. Bowser (D) announced an extended heat emergency that was to remain activated through the weekend and into Tuesday or until conditions improved.

The city encouraged residents and visitors to guard against heat-related illnesses and to check on neighbors.

Officials urged those without air conditioning to seek relief in air-conditioned buildings and cooling centers.

They said people could ask for accessible transportation to a cooling center for themselves or for others by calling the shelter hotline at 202-399-7093 or by dialing 311.

“Yurman is now back with his owner,” the police announced.

Yurman is a 2-year-old dark-colored male. It was not clear who found him or how. No information was provided about any arrest or charges.

Yurman’s owner was walking her dog in the 1700 block of Fort Davis Street SE about 8:20 p.m. on June 29 when someone approached with a gun, police said.

Police reported the robbery twice on social media, once just after it occurred and again with a brief surveillance video on Wednesday.

Numerous thefts of French bulldogs have occurred in the District and around the country.

In November, three were taken at gunpoint as they were being walked near the 5200 block of East Capitol Street, according to police.

Authorities said the robbers jumped from a vehicle and seized the animals.

Many of the dogs taken here have been recovered.

Purebred French bulldogs may sell for several thousand dollars and appear to be highly prized as pets. Authorities have said they are often taken to be sold.
