Residents and tourists in the Washington area sweated through the region's first heat wave of the summer Thursday, as the thermostat reached a high of 93 degrees and the sunny weather brought people out to the city in droves.

The mercury reached its highest temperature this year, with meteorologists predicting the hot weather is here to stay -- at least through the weekend.

National Weather Service meteorologist Dan Collins said Thursday was unusually hot for this time of year, but he said the high temperatures would not last through the month of June.

In the District, workers used the warm weather as an opportunity to get outside on Thursday afternoon. Some were sprawled out in Farragut Square grabbing a bite to eat, while others took a stroll on the National Mall. Tourists and school groups were out in full force, posing for pictures in front of the Capitol Building and relaxing by the reflecting pool.

The heat didn't stop George Nwador, 31, and Martin Cargas, 54, both of the District, from enjoying a pickup game of soccer on the Mall. The men are part of a twice-weekly noon game on Tuesdays and Thursdays. Nwador, who was playing on his lunch break, was drenched in sweat as he prepared to head back to work.

"I drank a lot of water before I came here," he said, wiping off his brow. "This is the hottest day we've played in so far."

Cargas agreed, saying the 30 or so men playing Thursday were hydrating and conserving their energy to deal with the heat.

"It's hard on us old guys," he joked. "We don't cancel games if it's too hot. The game just gets a little slower."

Amy Herrington, from Springfield, N.J., was leading a group of eighth-grade students on a tour of D.C. Students rolled up their sleeves, slathering sunscreen on each other and taking long drinks out of water bottles.

"When I looked at the weather last week, it said it was going to be in the 70s, and I thought, 'Great!' " Herrington said. "We haven't been outside much yet, but it is definitely hot."

In Montgomery County, Rockville resident Zina Hasan and her 18-month-old son, Nasem, splashed around in a fountain in front of the Rockville Memorial Library. They were joined by other small children and parents who were enjoying the water, as well.

She said she is looking for other activities, like the miniwater park in Rockville, for her and her son to keep cool.

"I don't mind the heat," she said, adding that she lived in California and in the Middle East before moving to Rockville. "It's the humidity I can't handle."
