Ah, summer in the Southern Hemisphere: Time to kick back in the great outdoors with a cooler-full of beer. Apparently, everyone in New Zealand has had the same thought though, and the country's biggest beer company is struggling to keep up. As the New Zealand Herald reports, Lion Breweries has fallen behind on deliveries on the country's North Island, as demand for Lion Red, Emerson's, Panhead, and other beers in Lion's portfolio has skyrocketed with temperatures pushing 80 degrees Fahrenheit. Lion has seen a 20 percent spike, and logistics workers are logging overtime to keep up. The company is used to stepping up deliveries in the summer, but this kind of sudden uptick is unprecedented.

"Summer arrived with a bang—it's like a light switch has been flicked, and that's the key reason demand has shot up," Lion spokeswoman Genevieve O'Halloran told the Herald. "We set high standards for ourselves and we are really upset and disappointed to be letting our customers down."

Lion's not the only beer distributor in the country, but it is one of two giants that together account for 84 percent of beer sales, so logistical woes make a serious dent when it comes to finding a six pack to bring to the cookout. The company says they are "making good progress" on catching up with Kiwis' thirst.

In the meantime, if you happen to find yourself in New Zealand as summer sets in, there are ways to enjoy yourself without beer. It's the world capital of outdoor adventure, after all, so why not try your hand at bungee jumping, river surfing, or canyoning—all activities best done sober. Alternatively, spend some days in Auckland, exploring its rising food scene and then hit the vineyards of Waiheke Island. No one said anything about a wine shortage.
