Traveller notes on St. Augustine in May
Other months in St. Augustine
St. Augustine's forum calls mid-March usually beautiful — mid-70s°F highs, low-60s°F overnight, mostly sunny. Regulars are honest the water itself is still too cold for swimming even when the beach is warm enough for shorts, and that a late-season cool snap can still turn up, so a layer is worth packing.
