OK - in a moment of Covid lockdown craziness I have performed the following analysis:
I have taken hourly average wind speed data from a meteorological station based at Wynnum from 2016 to 31 July 2021. (this is the Station in Nazareth House for the Wynnum-Manly locals. Given the station is not close to the water I have set a 'threshold' sailing speed of 8 knots. I have set sailable hours to be from 9am to 7pm; if the average hourly wind speed exceeded 8 knots during this period I has assigned the hour as 'sailable' and have then performed a count on the number of occurrences We have close to complete data sets for each year 2016 - 2020.
The results are tabled below. In order to allow for seasonal variation, I have then excluded the months August - December to have a like for like comparison.
2021 - so far would appear to be windier than previous years. With 2020 being the worst year we have had for a while. Regards,
Dr J
