(tl; dr — 10 years of English Channel weather data, in a single CSV file. And some fun charts.)
Weather can turn on a dime in the English Channel, and the dreams (and finances) of English Channel swimmers often turn on the weather.
Sandettie collects a variety of important meteorological data – air and sea temperatures, wind speed and direction, wave height and period, humidity, and barometric pressure. These data are then fed back to the UK Met Office, who publish the most recent 24 hours’ of observations on their website.
Anything before the last 24 hours are what the Met Office call “chargeable data” — at the rate of £6800 per 10 years, per two elements (e.g., air temp & sea temp). According to the today’s exchange rate, that converts to no less than $11,575 USD.
LOL! (And yes, I actually requested a quote from the Met Office.)
