Based on typical March conditions in Jacksonville. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
March in Jacksonville is one of the most comfortable months on the North Florida Atlantic coast — highs averaging 74°F, lows at 52°F, and 10 rainy days that are more spring showers than the sustained afternoon thunderstorms summer brings. Jacksonville Beach and Neptune Beach are accessible for beach days without the intense summer heat and humidity, and the St. Johns River waterfront neighborhoods of Riverside and Avondale are lovely for spring walks under the live oak canopy. The coastal breeze makes waterfront temperatures feel 5–8°F cooler than the forecast suggests — evening walks along the Riverwalk or Jacksonville Beach boardwalk are comfortable with a light layer when temperatures drop to the low 50s°F after sunset. The coastal-casual Florida style with a Southern edge fits March perfectly: a light floral sundress with a denim jacket for evenings, flat sandals for beach days, and breathable cotton for the warm afternoon temperatures. Summer's daily afternoon thunderstorm cycle hasn't started yet, but with 10 rainy days, a compact umbrella or packable rain jacket is worth including.
