Days until the start of the 100th Race
We are racing!

Good morning,
It’s hard to believe that this year’s Race is only three weeks away. If you haven’t done so already, it’s time to refresh your weather forecasting skills. Getting to the Island quickly and safely requires an understanding of the weather conditions you’ll experience along the way. There are many resources on my website to make the process easier:
— Managing Your Mack Forecast, a page describing where to find and how to use a variety of weather forecasting resources —
— Lake Huron Marine Weather Dashboard —
— Race Forecasts – daily weather forecasts will begin on Monday, July 10, 2023 at
— Weather Briefing – this year’s weather briefings will be virtual. A full video briefing will be posted on Friday afternoon, and a short video update on Saturday morning. Both briefings will be available at
Please contact me at with any questions.
