You're entitled to your opinion but you can't just go around telling people they're wrong and they're misleading people just because you disagree. Normally, 10-15 day forecasts are accurate roughly 50% of the time. 7 day forecasts are about 80% accurate. Get to 5 days and it's about 90% accurate. So obviously the closer the race gets the more accurate it can be. Future models use more estimates and assumptions than what actual forecasts do. However, much like last year, Florida (in particularly central Florida) is experiencing a second straight winter La Nina which brings with it a 70% chance of warmer weather and less rain. So, as we get closer more decisions can be made and plans can be finalized but it is unarguable that there is evidence out there at all to indicate the most likely weather patterns. Every athlete and vacation goer should continue to monitor changing weather patterns and if you want to keep your baclava, wool socks, tights, beanie, mittens, fleece and hand warmers at the ready, go ahead. Chances are, those won't be needed this year.
Anyone who wants to ignore future models and forecasts can absolutely do so. Pack and bring everything you own. BUT, that doesn't mean the info and data can't be useful.
