HERE COMES SUMMER; SUN'S FINALLY OUT, SCHOOL TO FOLLOW.

Byline: Melissa Schmitt Daily News Staff Writer

They're tired of school, and they're, like, way over bad weather.

Homework is history and there will be no more alarm clocks. Summer break starts this week, and for San Fernando Valley area teen-agers, that's not a second too soon. Summer's officially starting Sunday and the temperature's beginning to heat up - finally.

``I'm so sick of school,'' said Tiffany Saunders 15, with all the exuberance of a high-school freshman looking a three-month hiatus smack in the face.

School isn't officially out until Friday for most Los Angeles Unified School District students, with the exception of graduating seniors who were emancipated at noon Wednesday and those on a year-round calendar.

But with the newly arrived sunshine that burned the Valley on Wednesday, Saunders and her high school cohorts aren't waiting to celebrate.

``The weather has sucked,'' Saunders declared while waiting for the bus in front of Canoga Park High School with two girlfriends. ``It didn't even feel like it was summer until today. Now that it's sunny and (nearly) the last day of school, I feel better.''

If the National Weather Service knows what it's talking about, Saunders will have plenty to smile about in the days to come.

``If you liked today, you'll like the next several days,'' said meteorologist Rob Krohn.

``Valley temperatures will be in the 80s to 90 on Friday,'' he said. ``It'll be a great beach weekend.''

There will be some morning fog and low clouds, Krohn said, but otherwise it will be clear. ``It hasn't been warm all calendar year. This is going to be one of our first really nice breaks of warm weather.''

There will be no more waiting for 18-year-old Adrianna Coman, who will graduate today with her class at Taft High School.

Just minutes after being released from Taft at 12:30 p.m. Wednesday, Coman and several of her classmates gathered in their normal spot in the Ralphs parking lot off Winnetka Avenue trying to decide what to do next.

After tossing out a number of ideas of what she might do to pass the time this summer, Coman decided much of her summer would be spent working a part-time job, going to the beach and just hanging out. And in honor of a friend who was recently stabbed to death, Coman said she was planning to try to stay out of harm's way this summer.

``We're going to try to stay out of trouble,'' she said.

Whatever Isabel Abolian, 18, will be doing, so will Seama Eftekhari, 17, and Marjan Afshar, 18, all graduating today from Taft.

``Us three are one,'' Eftekhari said, standing between her two friends.

``I'm going to chill, go swimming. Have a barbecue,'' said Abolian, a resident of Woodland Hills. ``It's kind of depressing to leave high school, but it's good to move on.''

At Topanga State Beach, Jiyan Cohen, 14, of Topanga was already in his wet suit carrying his body board toward the waves Wednesday afternoon.

Cohen wasn't wasting any of the sunshine that has made itself so scarce this spring, heading for the pod of surfers at Topanga instantly.

Back at Canoga High, Suhai Franco, 18, sat quietly on the school lawn waiting for her ride home.

Her plan is to do some traveling - most likely Las Vegas for a couple of weeks, and then back home to start her new life.

``I'm probably moving out with a roommate and starting looking for jobs,'' Franco said.

Kimberly Omlie, 16, standing next to Saunders at the bus stop, said she's planning a couple weeks in New York, basketball practices, days at the beach and some fun with her friends.

``There's no curfew,'' Saunders said laughing ebulliently. ``My mom won't care if I go out late 'cause there's no school. She can't use that excuse anymore.''
