Longmont's heat and water situation

During this heat wave, Longmont's Drought Watch (Voluntary) water restrictions remain in effect. You can still cool off without violating them:

• Cool showers are unrestricted. Indoor water use is not limited by outdoor watering rules, so a cool (not cold) shower is the fastest safe way to drop your body temperature.
• Sprinklers count as irrigation. Running through a sprinkler may violate Longmont's outdoor watering schedule on non-designated days.
• Kiddie pools may be limited. Filling one uses outdoor water that can be restricted during drought.

For the current rules, fines, and your assigned watering days, see the Longmont water restrictions page.

Cooling down without air conditioning

In Longmont's dry desert heat your body cools efficiently through sweat — which also means dehydration sneaks up fast. Evaporative ("swamp") cooling genuinely works here: a damp sheet over an open window or a bowl of ice in front of a fan measurably drops the temperature, and misting your skin cools you quickly.

An estimated 35 million Americans have no home air conditioning. These CDC-aligned steps make a real difference:

• Close blinds and curtains during the day, especially on sun-facing windows.
• Open windows for a cross-breeze only when it's cooler outside than inside — early morning and late evening.
• Run ceiling fans counterclockwise; put box fans in windows at night to pull cool air in.
• Take cool showers and put wet cloths on your wrists, neck, and ankles.
• Stay ahead of thirst — a cup of water each hour, don't wait until you feel thirsty.
• Avoid using the oven or stove; grill or eat cold meals instead.
• Use evaporative cooling. A wet towel, a mister, or a bowl of ice in front of a fan works in Longmont's dry air. Hydrate constantly — you may not notice how much you're sweating.

How to spot dangerous heat illness

Heat exhaustion — heavy sweating, headache, dizziness, nausea, weakness, and cool, clammy skin. Move to a cool place, loosen clothing, sip water, and apply cool cloths. If it doesn't improve within an hour, get medical help.

Heat stroke is a 911 emergency — body temperature of 103°F or higher, hot/red/dry skin, a rapid pulse, confusion, and little or no sweating. Call 911 immediately, move the person to a cool place, and cool them with wet cloths or ice. Do not give fluids to someone who is unconscious.

Highest risk: older adults, young children, outdoor workers, people with chronic conditions, and anyone without AC. Never leave children or pets in a parked car, and check on elderly neighbors during a heat wave.

If the power goes out during the heat

Grid strain during heat waves can cause outages right when you need cooling most.

• Call 211 to find a cooling center if your power is out.
• Keep the fridge and freezer closed — food stays safe about 4 hours in an unopened fridge and up to 48 hours in a full freezer.
• Never run a generator indoors or in a garage — carbon monoxide is deadly.
• Charge phones and any medical devices before an expected outage.
• Keep refrigerated medications in an insulated cooler; don't place them directly on ice.
