The weather won't be all that great but there's still plenty to do around Calgary this weekend.

Lemonade Day in Calgary

Don’t let the rainy weather fool you, the first-ever Lemonade Day in Calgary goes Saturday when 65 juice stands will be set up in all four quadrants of the city.

The Calgary Chamber of Commerce is partnering with Junior Achievement Southern Alberta to put on the event, which will see kids in Grade 4 to 7 operate the stands.

Saturday’s forecast calls for a high of 12 C with scattered showers.

A map to stand locations can be found here.

Riddim West

It’s not every day you get to reggae. Join fellow Rastagarians in celebrating all things reggae this weekend at Riddim West, going Saturday at MacEwan Hall on the University of Calgary campus.

Performers from across Canada and around the world will hit the stage for Riddim West, which is a rebranded version of ReggaeFest, now in its 15th year.

Doors open at 2:30 p.m. and shows begin at 3 p.m. with a performance by Phonosonics (Victoria), culminating with Lynn Olagundoye (Calgary) Hawkeye (Jamaica), Luciano (Jamaica) and Cham (Jamaica).

An interactive kids zone will be open from 2:30 to 8 p.m.
