Hi Product Hunt 👋 I live in San Diego, where the question every commuter asks is when to leave for the border. CBP publishes the wait right now; the moment it changes, the old number is gone. Nobody keeps the history. So since August 8, Tempo has logged CBP's published wait for every US land crossing, every hour. San Ysidro alone shows something nobody had written down: weekends are quietest around 4am (~25 min) and worst around 4pm (~165), and Otay is often an hour faster on Saturday afternoons. Every crossing has an hour-by-hour page on the site, free, no sign-up. The app adds every lane live, a 7am brief on which crossing to use, and an alert when yours drops under a number you pick. Parks work the same way. Free, no ads. Happy to pull any crossing or date range.

Six weeks of hourly CBP data: San Ysidro on a Saturday is 25 min at 4am and 165 at 4pm

Since August 8 I've been logging CBP's published wait for every US land crossing, every hour. The first clear finding from San Ysidro: weekdays and weekends are two different crossings. Weekdays are quietest around 10pm and worst around 11am. Weekends are quietest around 4am and worst around 4pm. Otay's weekend peak is 9pm, so on a Saturday afternoon Otay is often an hour faster.

Every crossing, hour by hour, is free here: skipthewait.app/border-wait-times
