Interesting. I'd have though you'd have far more. We've averaged 4.6 over the last 20 years here.

Over the last 11 years I have averaged 15 thunder days a year. Most
occur during the June to September period but there is a second 'peak'
in November and December (probably due to being surrounded by a warm sea
at that time).

The least thundery, i.e., practically zero thunder days occur February
to mid-March. I presume this is because the sea is about at its coldest.
