Code Red Heat Alert & Rules

On days and periods of extreme heat, the Baltimore City health commissioner may declare a Code Red Heat Alert for the safety of residents. The decision to activate a Code Red Heat Alert will be made before 6 a.m. of that day, if possible.

When a Code Red Heat Alert is in effect, normal swim sessions (adult, family, and lap swim sessions) will be suspended and pools will operate on two-hour open sessions with a 30-minute intermission.

**Clifton and Patterson Parks pools do not follow the Code Red schedule. Pools operate as normally scheduled.

NEIGHBORHOOD/WALK-TO POOLS will operate three (3) swim sessions:

  • Noon - 2:00 p.m.
  • 2:30 p.m. - 4:30 p.m.
  • 5:00 p.m. - 7:00 p.m.

Capacity: 100 swimmers per session

PARK POOLS will operate four (4) swim sessions:

  • Noon - 2:00 p.m.
  • 2:30 - 4:30 p.m.
  • 5:00 - 7:00 p.m.
  • 7:30 - 9:00 p.m. or dusk

Capacity: 300 swimmers per session 
**Operating schedules at Patterson and Lake Clifton Park Pools will remain the same

All swimmers must exit the facility at the end of each two-hour swim session. At the end of intermission, swimmers must pay (or repay) the admission fee to enter the pool. This rotating schedule provides all swimmers an opportunity to enter the pools on days when attendance is high.

Admission to Baltimore City park pools is $2 per two-hour Park pools session and $1 per two-hour session for neighborhood walk-to pools.
