Toronto will see daytime temperatures reach an abnormal high for early September this week, Environment Canada said Saturday. 

The government agency issued a heat warning for the city on Saturday, saying a hot air mass will raise temperatures from Sunday to Wednesday. 

"Despite overnight temperatures being lower than warning criteria in some areas, humidex and daytime highs will be very atypical of early September," Environment Canada said. 

Maximum temperatures could reach 31 C, with humidex values — meaning how hot it will feel — potentially rising to 40 C. 

During the heat wave, Environment Canada says people should drink water before they're thirsty and check on older family, friends and neighbours to ensure they're staying hydrated and cool.

How the city responds to the heat

This heat wave will sneak under the wire of the city's heat relief strategy, which runs from May 15 to Sept. 30. 

As part of the plan, city staff provide outreach to those living outdoors to help them find relief at shelters and 24-hour respite sites. 

The city also has a network of heat relief areas where people can find relief from the warm temperatures, a spokesperson said in an email to CBC Toronto. People can find a cool space near them through the city's interactive map.

The network includes libraries, community centres, pools, wading pools, splash pads, civic centres and several private and non-profit organizations, including some shopping malls, senior centres and YMCA locations.

If you're looking to cool off with a swim, the city is also keeping 10 pools open into September this year. Pools will be open 4 p.m. to 7 p.m. on weekdays and 12 p.m. to 7 p.m. on weekends. 

Those 10 pools include: 

  • Alex Duff Memorial Pool – 779 Crawford St.
  • Heron Park Community Centre – 292 Manse Rd.
  • Kiwanis Outdoor Pool – 375 Cedarvale Ave.
  • Leaside Outdoor Pool – 5 Leaside Park Dr.
  • Ledbury Park Outdoor Pool – 160 Ledbury St.
  • McGregor Park Community Centre – 2231 Lawrence Ave. E.
  • Monarch Park Outdoor Pool – 115 Felstead Ave.
  • Pine Point Park Outdoor Pool – 15 Grierson Rd.
  • Sunnyside Gus Ryder Outdoor Pool – 1755 Lake Shore Blvd. W.
