Pick your sport and BlockCast scores every 2 to 6 hour block of your week green, yellow or red: rain from three models, wind and gusts, feels-like, UV, snow base, waves. Plan a session, add it to your calendar, and get alerted if it turns. Free, no account.







Hi Product Hunt! I'm Sandy, and I built BlockCast in Québec.
Weather apps answer "will it rain at 3?". When I'm planning a week of sport I want a different answer: which block of which day is best for this activity. So BlockCast takes one sport and scores every block of your week from live forecasts, with weights that differ per sport. Wind matters more for pickleball than for tennis, heat matters more for running than rain does, and skiing cares about the snow base first.
A few details: green only shows when three forecast models agree on dry, there's no account and nothing tracked, and you can now share any block as a link that opens the same forecast for your group.
It's free on iPhone (Canada and US) and works in any browser. I'd love to hear which sport you'd score and whether the defaults match your judgment.
