Hell yeah, it is! Kili is misleading with its own seasons and climate. We were sweating at the base camp in the 30-degree heat. But as the days went on and the higher we climbed, the colder it became. Especially at night. Those couple of days in high-altitude before we reached the summit were beyond freezing. Even during the day. I was applying layer after layer - thermals, 3 pairs of socks, sweatshirt, jacket, waterproofs, woolly hat, gaiter and 2 pairs of gloves. I was still cold. I learned that it’s important to take those layers off at night for a short amount of time, then only re-apply a few of them before sleeping. I ended up keeping on the same hundred items day and night, which meant my body couldn’t adjust to the minus temperatures. Minus 15 to be exact. I was so focused on climbing that I didn’t realise how cold my feet were. Even to this day, my toes suffer in the slightest cold weather, and my toenails have never been the same…
