If it's not a flashback, you can use present tense! A lot of YA books are written in present tense, and they use the same tense to summarize events.
Example from Boy Meets Boy (David Levitahn) (no copyright intended):
[Joni] drives us aound in the family sedan. We roll down the windows and crank the radio - we like the isea of music spilling out over the neighbourhood.
Examples from Fly on the Wall (E. Lockhart) (no copyright intended):
Tuesday and Wednesday are uneventful. Pop leaves for Hong Kong, and it's a relief, since he and Ma have been snipping at each other every time I leave the room. One day, the day before he leaves, he smells like cigarettes again, which makes me wonder if he is bringing is girlfriend on the business trip with him. But I don't speak about it.
Then, on Thursday, Titus comes up to me in the hall.
We walk around the room, looking at what other people have done. Kensington is giving quiet critiques to people, one at a time. Surprisingly, she doesn't say anything to me at all.
