Penticton Peach Festival organizers are expecting this year鈥檚 festival to be the biggest in its history, as they prepare to enter its 70th year.

Peachfest鈥檚 kids鈥� zone will be opening up at 9 a.m. in Gyro Park, with peach bin races and entertainment kicking off the festivities at noon.

鈥淓veryday is a big day, but Wednesday we鈥檝e got the air show and as well as 54-40 headlining,鈥� said Peachfest president Don Kendall. 鈥淵ou have the motocross, there are the two shows on Wednesday. It鈥檚 a huge day.鈥�

As smoke continues to fill the Okanagan Valley, with haze in Penticton considered a high-level risk, the Snowbirds are still unclear whether they will be able to perform their aerobatics show, scheduled for 6 p.m.

But Kendall pointed to fluctuating air conditions both recently and in the past, noting that the Snowbirds were forced to do their 鈥渓ow show鈥� four years ago after the skies changed from clear at 1 p.m. to hazy at 5 p.m.

鈥淣obody can predict what the weather鈥檚 going to be like. You hope for the best, but there鈥檚 nothing we can do about it,鈥� he said, noting they likely won鈥檛 make the decision until just before the show.

According to a news release, if the Snowbirds are unable to fly for the show, they will do a meet and greet with the public at the Okanagan Lake Park.

Save for a near-zero visibility come 5 p.m. tomorrow, however, the Canadian Forces Skyhawks Precision Parachute Team is fully expecting to put on their aerial show for crowds.

A CF-18 Hornet fighter jet show is scheduled to run after the Snowbirds, at 6:45 p.m., which officials say will go on regardless of the smoke conditions.

Kendall pointed back to the motocross, which will also go on regardless of the smoke conditions, adding that last year鈥檚 first appearance at Peachfest was a success.

鈥淚t ran on one day last year with two shows and attracted about 7,000 people for the two shows, so we鈥檙e thrilled to have them back this year for three days, two shows a day,鈥� Kendall said.

鈥淎nd this is, without doubt, the best entertainment lineup we鈥檝e ever had.鈥�

Kendall said Trooper recently played for $40 tickets in West 琉璃神社, while 54-40 played Tinhorn Creek winery last year with $80 tickets.

鈥淵ou come to Peachfest and see these people for nothing,鈥� Kendall said. 鈥淵ou don鈥檛 get to see bands like Aaron Pritchett and Trooper and 54-40 and Powder Blues for free.鈥�

Beyond the entertainment, Kendall noted a slo-pitch tournament, square dancing, a skateboard and BMX competition and two parades.

鈥淚t鈥檚 a lot more than just the entertainment,鈥� he said. 鈥淭he fact that thousands and thousands of people every day get to enjoy this for free is incredible.鈥�

The Penticton Okanagan Rotary will also be holding their 34th annual sandcastle competition on Thursday, with registration running at 4 p.m. and sculpture time kicking off at 5:30 p.m.

Last year attracted an estimated 80,000 event visits at the festival, which was about the same as 2015, though it鈥檚 unclear how many individual people attended Peachfest.

But this year, Kendall said he鈥檚 looking to break that record.

鈥淲e expect record crowds. We鈥檝e got the best parade we鈥檝e ever had, we believe, we鈥檝e got the best entertainment lineup we鈥檝e ever had. We鈥檝e got tremendous events throughout the five days for people of all ages.鈥�

Part of the reason 2015鈥檚 numbers hit as high as they did in 2016, however, was because an estimated 20,000 people watched the Snowbirds do their show.

鈥淲hen they perform, Okanagan Lake Beach, all the way around is wall-to-wall people. You can鈥檛 even see the sand,鈥� Kendall said.

鈥淭he traffic stopped on Highway 97 last time to watch them. And up on Munson Mountain and Naramata way, the roads were all clogged by people watching them.鈥�

With that in mind, Kendall noted it鈥檚 best to be patient when travelling during Peachfest, adding that transit might be the best option for most people attending the festival, with limited parking and plenty in attendance.
