PolarLava CycleLog V2.3.0
An afternoon of hacking at it and the CycleLog now has a quick Weather Check page. This little project simply looks up the weather in the database for a given date —generally today or something in the past couple of weeks. Anything older than that won't exist as it gets purged except for weather data associated with a ride. Way too much data to keep around otherwise. To access a particular date you pass it as a "YYYY-MM-DD", "d" or "date" GET parameter, so for example "?d=2006-06-11" (2006-06-11).
Sometimes on days I take longer rides and the weather is variable, I will look up the most appropriate (prevalent) conditions during the ride. This differs from my standard practice of using the closest hourly weather to when I finish the ride. And now you can forget about this because I'd guess I'm the only one who really cares. :)
