Great Loop Timing

Great Loop Month-by-Month Planner

The Great Loop is a seasonal puzzle. The right month depends on your start point, route variant, boat speed, insurance limits, heat tolerance, cold tolerance, and how much you enjoy waiting for weather. Use this as a planning calendar, then verify current conditions before moving.

Last reviewed: 2026-06-26. This is planning guidance, not navigation advice. Check current charts, notices, lock schedules, bridge restrictions, weather, insurance limits, and marina availability.

January

Best use: refit, survey follow-up, Florida/Gulf staging, shakedown weekends.

Watch: winter fronts, yard delays, parts delays, insurance restrictions.

Do: run every system, fix leaks, test heat/AC, rehearse anchoring and dock approaches.

February

Best use: route decision cleanup, provisioning templates, customs and documentation checks.

Watch: last-minute upgrades becoming schedule traps.

Do: create a conservative spare-parts list and confirm insurance navigation language.

March

Best use: Florida movement, ICW practice, Okeechobee/coastal decision planning.

Watch: early thunderstorm patterns, bridge fatigue, calendar optimism.

Do: start slower than you think. Crew rhythm is more valuable than mileage.

April

Best use: Atlantic ICW progress, bridge routines, marina/fuel rhythm.

Watch: shoaling, currents, spring weather windows, popular stop compression.

Do: keep a daily bridge note and call ahead when a stop matters.

May

Best use: Chesapeake, Delaware Bay staging, New Jersey coast planning.

Watch: exposed legs, fog, cold fronts, canal timing uncertainty.

Do: stage patiently for Delaware Bay and outside/coastal hops.

June

Best use: Hudson, Erie/Champlain decisions, canal towns, northern transition.

Watch: canal notices, bridge/lock closures, high-water or maintenance delays.

Do: verify air draft and canal restrictions before committing to a branch.

July

Best use: Trent-Severn, Georgian Bay, North Channel, Great Lakes cruising.

Watch: big-lake weather, dock demand, remote-service gaps.

Do: preserve fuel margin and choose harbor pairs before crossing open water.

August

Best use: northern cruising, Canada if chosen, slower scenic legs.

Watch: vacation crowds, storms, smoke/visibility in some years, parts scarcity.

Do: reserve key stops and do maintenance before heading into sparser service areas.

September

Best use: Lake Michigan southbound, river staging, fall positioning.

Watch: cold fronts, lake fetch, harbor spacing, shorter days.

Do: stop treating summer daylight as normal. Build earlier arrivals.

October

Best use: inland rivers, tow/lock discipline, southbound progress.

Watch: debris, current, commercial traffic, closures, limited fuel.

Do: plan fuel and anchorages with backups before the day starts.

November

Best use: Gulf Coast, Florida return, warmer-water reset.

Watch: fatigue after river segments, storm-season leftovers, holiday schedules.

Do: schedule a real rest stop, not just a repair stop.

December

Best use: winter base, family logistics, boat reset, slower cruising.

Watch: crowded warm-weather marinas and deferred maintenance temptation.

Do: review what the boat taught you and update the next season's plan.
