Marvel Cinematic Universe - Timeline (Part 4)

Luis speaks to the writer chick that says they have superheroes that "crawl up the walls", clearly referring to Spider-Man, who says he had his powers for six months (insert riot here) by Civil War, which also has warmer weather

Given this is a world with a number of enhanced individuals it doesn't have to specifically be a Spider-Man reference. Even if it was intended to be it doesn't fit. That epilogue is very shortly after the climax of the movie, like a week at most. And saying it's 4 months later is a huge stretch done only to force the reference to be Spider-Man. The site here agrees and places the scene in August.
