Long heat wave expected this week
The big focus of the weather forecast this week is a long duration heat wave through Labor Day Weekend.
An impactful, long duration heat wave is expected from the beaches to the desert through Labor Day. High to very high heat risk will impact the coast and valleys. Plan ahead now so you can stay cool and hydrated, especially if you have outdoor plans.
The San Diego Office of the National Weather Service issued an Excessive Heat Warning for Tuesday, Sept. 30, 10 a.m. through 8 p.m. on Monday, Sept. 5. Hot conditions with high temperatures of up to 115 degrees may be reached.
Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. Humidity will be high as well making it feel even hotter than the actual air temperatures. Low temperatures will only fall into the lower to mid 70s each night.
- Extreme heat increases the risk for heat-related illnesses and can affect those working or participating in outdoor activities.
- Drink plenty of fluids, stay in an air-conditioned room if one is available, stay out of the sun and check up on relatives and neighbors by telephone, video call or in-person.
- Young children and pets should never be left unattended in vehicles at any time.
- Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening.

Dress for the heat; lightweight and light-colored clothing. Eat small meals and eat more often. Monitor those with a higher vulnerability to heat, including small
children. Check in on family, friends and neighbors, especially the elderly. If engaging in outdoor activity, take longer and more frequent breaks and avoid the hottest parts of the day. Never leave kids or pets unattended in cars.
