Friday has arrived in Toronto, bringing with it another hot and sunny weekend as the city remains on the cusp of a heat alert.

The late September heat wave has city officials urging caution ahead of weekend events.

"For this time of year, we are way above where we should be and we're getting into record territory," said Geoff Coulson, warning preparedness meteorologist for Environment Canada.

The weather agency issued a heat warning for Toronto and the Greater Toronto Area as warm temperatures and humidity are expected to persist throughout the weekend.

With a high of 31 C expected on Saturday and 32 C on Sunday, the city has pledged to keep the majority of splash pads open for the weekend.

The Invictus Games also start on Saturday and run until September 30, bringing plenty of things to see and do.

The games will also affect how you get around this weekend in areas near to where events are being held.
