In Miami, look for summer concerts, food festivals, and private art events that increase hotel demand in Miami Beach and downtown.

When traveling in August, check local event calendars and book transfers early to avoid surcharges and availability issues.

For August travel from Jacksonville International Airport (JAX) to Miami International Airport (MIA), the best time to fly is early morning (departures before 9:00 AM) when thunderstorms and hurricane-related disruptions are less likely. Mid-week flights (Tuesday–Thursday) often offer cheaper fares and lower airport crowds. Avoid late-afternoon departures when summer convective weather commonly causes delays in the Southeast. If flexibility is possible, book at least 3–6 weeks in advance and choose refundable or changeable fares during the Atlantic hurricane season.

Direct (nonstop) flights from Jacksonville International Airport (JAX) to Miami International Airport (MIA) save time — typically under 2 hours — and reduce the chance of missed connections during August storms. Connecting flights can be cheaper and offer more scheduling options but add risk of delays through busy hubs like Atlanta (ATL) or Charlotte (CLT), especially during hurricane season. If time is critical, choose nonstop; if budget is the priority and you can allow extra connection time, a one-stop itinerary may save money.
