Welcome. Here in New York, it’s officially summer. If it’s hot where you are, your exercise regimen may need some modifications. Gretchen Reynolds has ideas — including freezing your underwear. Sam Sifton is fishing for fluke, a highlight of his summer meals. And Concepción de León has information on how the Delta variant of the coronavirus may affect your travel plans.

Last week I asked when summer truly begins for you. For me, it’s when I can leave the house without a jacket or socks, when it’s warmer outdoors than indoors, the air nearly the same temperature as my skin. Here’s what you said.

• Summer has begun when I’ve killed my first mosquito. That tells me the weather is warm enough to get moving and enjoy our short summer. Usually this happens mid- to late May. —Eugenia Wright, Anchorage, Alaska

• The happiest day of the year for me is when my husband takes the tarp off the patio furniture and puts the umbrella back through the hole in the table! That’s the signal that great outdoor weather is on its way! —Eva Steen, New City, N.Y.

• It starts when it’s warm enough to go outside without a coat (early June) and ends when the rain comes back (mid-June). —Rachael Fairbairn, Edinburgh, Scotland

• When my son catches the first firefly of the season. —Megan Nelson, Beloit, Wis.

• I know summer is here when I turn on the cold water tap and it comes out warm enough to wash my hands. —Wendy Van Syckle, Bellaire, Texas

• I have been teaching for 38 years and summer always begins for me when the students have moved on, and I have packed up my classroom once again. It takes a few days for it to sink in, but gradually I stay up a bit later and begin to dig in to all of those projects I have put off during the school year. —Carol Stuhff, Sandy, Utah

P.S.

• The final episode of “Conan” airs Thursday night on TBS. Check out Dave Itzkoff’s interview with Conan O’Brien’s longtime sidekick, Andy Richter.

• In The New Yorker, Doreen St. Félix takes a look at Ziwe’s new late-night show: “Ziwe, dressed in gorgeous high-femme outfits that verge on the parodic, is our demented girl boss, our anchor, which means we are always a bit seasick.”

• And, in keeping with the theme, here’s Lucy Dacus performing her new song “Brando” on “Jimmy Kimmel Live.”
