In 2020 there was a us wave in jul/august. This was strongest in the south. In 2021 there is also a july/august wave, strongest in the south. It is more present in the north than last year’s wave, but not at its biggest there. My prediction is the north will see a bigger wave later in the year as people head inside. You can’t exclude variants either. Alpha was more contagious and got around the world by May, so that trumps seasonality. The May wave also began march/april and peaked later. But for any given variant it would be extremely unusual to see highest activity in summer not winter.
