Yes, you can definitely brew your lager year-round! While traditional lager yeast thrives in cooler temperatures (around 10-14°C), there are ways to brew similar styles during warmer months.
One option is to use a clean, neutral ale yeast like US-05 or Nottingham. These yeasts ferment at warmer temperatures (around 18-22°C) and produce fewer fruity esters, giving you a "pseudo-lager" with a clean profile. As mentioned by others, you could even experiment with yeasts like Kveik, which can tolerate very high temperatures without producing too many off-flavors.
Some lager yeasts, such as the Weihenstephan 34/70 or Novalager, can be fermented at higher temperatures (up to 20°C) without generating too many esters, which means you can make a crisp beer even when it's warmer out.
Ultimately, the yeast you choose will impact the flavor and body, but you can get close to a lager profile even in the summer. If you're up for experimenting, you could split batches and try a few different yeasts to see which one gives you the results you prefer!
