Frequently asked questions about Guatemala City's climate
Is Christmas getting warmer in Guatemala City?

How many tropical nights does Guatemala City get now?
Guatemala City averaged 0 nights a year that never cooled below 20°C in 2015 to 2025, about the same as 0 in 1976 to 1986. A night like that is the main reason sleep gets worse during a heatwave, the body can't cool down enough to reach deep sleep.
How long do heatwaves last in Guatemala City now?
The longest unbroken run of exceptionally hot days now averages 11 days a year, up from 7 days in Guatemala City's own early record. The threshold is Guatemala City's own 95th percentile hot day from the 1976 to 1986 window, not a fixed number for every city, so this measures how the city's own definition of too hot has shifted, not just how often it crossed some fixed temperature.
Is the pavement too hot for dogs in Guatemala City?
On 205 days a year now, the temperature passes 25°C, hot enough that asphalt or sand in full sun reaches roughly 52°C, the point vets say a dog's paw pads start to burn within about a minute. That's up from 127 days in the 1976 to 1986 window. The simple test, press the back of your hand to the pavement for seven seconds, if that's too hot for you, it's too hot for a dog.
How hot does a parked car get in Guatemala City?
Guatemala City now has 362 days a year warm enough, above 20°C, for a closed car in the sun to get hot enough to melt chocolate left on the seat, up from 361 in the early record. A closed car reaches that point within about an hour, which is also why leaving a child or a pet alone in the car, even briefly, is dangerous on far more days than it used to be.
Are dry spells getting longer in Guatemala City?
Not here. The longest dry stretch has actually gotten shorter, from an average of 65 days in 1976 to 1986 to 53 days now, Guatemala City is one of the capitals in this dataset trending wetter rather than drier. Longer dry spells matter for sprinkler bans and cracking in clay soil foundations.
Is insect season getting longer in Guatemala City?
The warm season here, days averaging above 10°C, is now about 5.6% warmer than in 1976 to 1986. Under the Q10 rule from biology, insects and mosquito larvae develop roughly twice as fast for every 10°C of warming, so this difference translates into noticeably faster breeding cycles, one reason insect season starts earlier and runs longer than it used to.
