The question is simple, Do more people die during cold or hot weather. In colder weather people catch more viruses, road conditions are more difficult, there is more depression due to less daylight. Statistically there are more deaths in cold weather. In Canada we know the weather changes drastically from January to June. The extreme cold for Canada is -40c, once every 25-30 years it does snow in Los Angeles. People in San Francisco wear winter clothing during the winter months to keep warm in 5c. weather like we wear in -20c. In the Southern hemisphere it also gets cold, but in June, what ever the weather change for the area you live in colder weather does bring on more deaths from viruses, depression and accident.
