[[Principal photography]] began on March 16, 1992, and concluded on June{{nbsp}}10, after 86 days.<ref name="TCM" /> The budget was reported to be between $14.6{{nbsp}}million and $30{{nbsp}}million.<ref name="VarietyBudget" /><ref name="morning call" /><ref name="TheNumbers" /> Filming took place mainly in Woodstock, as well as on sets in [[Cary, Illinois]], and [[Hollywood, Los Angeles|Hollywood]].<ref name="morning call" /><ref name="PennLive" />

Weather conditions varied considerably during filming. Much of the shoot was conducted in conditions described as frigid and bitterly cold.<ref name="Varietyat25" /> Murray estimated that it was often {{convert|20|F|C}}. The conditions persisted until the end of May. Murray said that being outside for up to 12 hours a day left his skin feeling raw and made him irritable.<ref name="morning call" /> Toward the end of the shoot, as summer began, fake snow was used to replicate the winter setting, and the actors continued to wear their winter gear despite the rising heat.<ref name="AVClubShannon" /> Ramis could not decide on the weather conditions for the background of Phil's and Ned's encounters, so he shot their nine scenes multiple times in differing conditions. He settled on a gloomy setting to indicate a loop coming to an end.<ref name="Varietyat25" /> Weather conditions were a major factor in a two-week shoot for the car crash scene.<ref name="JournalStandard" />

The shoot was also mired in tensions between Ramis and Murray; Ramis was focused on making a romantic comedy, in direct contrast to Murray's desire for a more contemplative film.<ref name="Varietyat25" /><ref name="ReadersDigest" /> Murray was also in the middle of a divorce from Margaret Kelly.<ref name="LATIMesRamis" /> He was reportedly miserable throughout filming, demonstrated erratic behavior, threw tantrums, and often contradicted Ramis's decisions.<ref name="uproxx rift" /><ref name="ReadersDigest" /> Ramis said that Murray constantly showed up late to set, calling his behavior "just irrationally mean and unavailable."<ref name="ReadersDigest" /> The two also disagreed about the script and other actors' performances.<ref name="LATIMesRamis" /> Shannon recounted how he believed he had upset Murray during an encounter. When Ramis heard about this, he made Murray publicly apologize to Shannon.<ref name="AVClubShannon" /> Tobolowsky recounted how before their scene's first take, Murray walked into a bakery and bought all the pastries, which he threw to the gathered onlookers, using Tobolowsky to help carry the load.<ref name="NorthWestHerald" />

The script continued to change during filming. When Tobolowsky arrived for his first scene, he was handed a new script. He estimated that about a third of it was different from his original copy. For example, early in the film, Phil ends his first loop by breaking a pencil to see if it is repaired the following day. A more elaborate scene was filmed in which Phil spray-painted the walls of the room he wakes up in, destroyed objects, and gave himself a [[Mohawk hairstyle]]. The scene took three days to film and was costly; Ramis discarded it for something quieter, simpler, and less manic. The revised script also featured more of Phil's misadventures, and his suicide attempts were set closer to the end. These scenes were moved forward in favor of a long third act showing Phil embracing life.<ref name="SeattleTimes" /><ref name="NorthWestHerald" />

Murray endured physical discomfort for some scenes. To prepare for his step into the water-filled pothole, he wrapped his foot in cling wrap, neoprene, and two pairs of socks. As soon as the scene finished, he began an expletive-filled rant until the costume department dried his foot with hairdryers to avoid frostbite.<ref name="Varietyat25" /> For another scene, Murray asked MacDowell to really slap him, and Ramis instructed the children Murray confronts in a snowball fight to throw hard.<ref name="TheWrap" /><ref name="ReadersDigest" /> During the scene in which Phil drives off with Punxsutawney Phil, the groundhog bit Murray on the knuckle. Although Murray was wearing gloves, the bite broke the skin. During a later take, the groundhog bit him again, in the same spot.<ref name="PhillyBeast" /><ref name="Mentalfloss" />

Murray was hesitant about shooting the final scene in which Phil awakens next to Rita, as how or whether Phil was dressed would affect the tone of the revelation that he had escaped the time loop. Ramis polled the crew, who were split between Phil wearing the same clothes as the previous night and different clothes that suggested the pair had been intimate.<ref name="Varietyat25" /> A young female crew member served as the tiebreaker, ruling that they should be wearing the same clothes as "anything else... will ruin the movie."<ref name="Varietyat25" /> As MacDowell's and Murray's characters venture outside the Cherry Street Inn in the film's denouement, the scripted line "Let's live here" is tempered by a Murray ad lib, "We'll rent to start."{{sfn|Gilbey|2004|pp=80–81}}

Many locations in and around Woodstock were used in the production. The Woodstock Town Square features prominently. A bar in the former courthouse is used for a bar in Rita's hotel. The Woodstock Opera House served as the exteriors of Rita's hotel, and its tower is used for Phil's suicide leap.<ref name="PennLive" /><ref name="LocationHub" /> The Cherry Street Inn was a private residence; the interior was shot on a set.<ref name="PennLive" /> Woodstock City Lanes was used for the bowling alley scene.<ref name="LocationHub" /> The Tip Top Cafe, a setting for several scenes, was purpose-built for the film. Local demand later led to a real diner with a near-identical name at the same location.<ref name="LocationHub" /><ref name="HuffPoCafe" /> The bachelor auction where Phil demonstrates his personal transformation was filmed at the Woodstock Moose Lodge.<ref name="PennLive" /><ref name="LocationHub" /> The shots of Murray being nearly run over by a train were filmed at the nearby [[Illinois Railway Museum]].<ref>{{cite web |title=Chicago Burlington & Quincy 504 |url=https://www.irm.org/player/cbq504/ |website=Roster of Equipment |publisher=Illinois Railway Museum |access-date=18 August 2024}}</ref><ref>{{cite web |title=Press and Filming |url=https://www.irm.org/press-page/ |publisher=Illinois Railway Museum |access-date=18 August 2024}}</ref><ref>{{cite web |title=The Museum in the Movies |url=https://www.irm.org/movies/ |publisher=Illinois Railway Museum |access-date=18 August 2024}}</ref> The scene of Phil driving a truck over a cliff was shot in Nimtz Quarry in [[Loves Park, Illinois]], about {{convert|34|mi}} from Woodstock. A rail system was used to propel two vehicles into the quarry on separate takes, to give Ramis a choice of shots; pyrotechnics were employed to make each explode.<ref name="JournalStandard" />
