Note that if the climate at a place isn't changing we'd expect new records for a given thing to become less frequent over time. For example suppose you had something where it follows a normal distribution with a mean of 100 and a standard deviation of 5. I generated 10 million random numbers with that distribution and noted whenever I got a new record high. The intervals between records were 1, 1, 2, 1, 5, 36, 219, 999, 2558, 21780, 397, 50360, 73288, 200951, 652234, 954240, 547715, 3783984, and 1641056.
