Visiting in Summer on the Gulf Coast

Summer here is not a mild inconvenience. Temperatures in the nineties with humidity to match, and an insect load that surprises visitors from almost anywhere else.

None of that makes a summer visit a bad idea. It makes timing and preparation the difference between a pleasant morning and a miserable hour.

Go early. Not "reasonably early" — early.

Sunrise to about nine is the usable window. By ten the heat is significant, by noon it is genuinely unpleasant, and the wildlife has largely shut down anyway.

The second window is the last hour and a half before sunset, which is cooler but has the worst mosquito activity of the day.

Given the choice, morning.

Heat, honestly

Gulf Coast humidity prevents sweat from evaporating, which is how the body cools. The practical effect is that the temperature reading understates the load substantially.

Drink before you're thirsty. Thirst lags dehydration.

More water than you think. A litre for an hour's walk in July is not excessive.

Rest in shade before you need to. The canopy here is good; use it.

Know the warning signs. Stopping sweating, confusion, nausea, headache. Any of these means getting out of the heat immediately.

Heat illness on this coast is a real risk for visitors who are used to dry heat and misjudge it.

Insects

Mosquitoes. Present from April, serious from June. Repellent containing DEET or picaridin, applied before you leave the car and reapplied. Long sleeves in light fabric are more comfortable than they sound and more effective than repellent alone.

Chiggers. The particular Gulf Coast misery. Larval mites in low vegetation and leaf litter; the bites appear hours later and itch for a week. Prevention: stay on the trail, treat clothing with permethrin, tuck trousers into socks, shower promptly after.

Ticks. Present. Check afterwards, particularly at hairlines, waistbands and behind knees.

Yellow flies. May and June specifically. Aggressive, and largely undeterred by repellent. Light-coloured clothing helps somewhat; timing helps more.

What's actually good about summer here

Jubilee season. June through September, early mornings, on the right conditions. Nothing else on this coast compares.

Wading birds are active along the shoreline, and the falling tide concentrates fish into shrinking shallows.

Nesting season. Resident birds are feeding young, which means constant activity and predictable behaviour.

Early shorebird migration begins in July — the earliest movement of the year, and one most people miss.

Storm light. Afternoon thunderstorms on this coast build enormous cloud structures. Watch from somewhere safe.

Thunderstorms

Afternoon storms are near-daily in summer and can develop very quickly.

Lightning is the actual danger, and mature trees are the worst place to be. If you hear thunder, you are within range. Leave for the car.

The rain is usually brief. Waiting it out in a vehicle is the correct move.

The short version

Be on the trail by seven. Repellent before you get out of the car. More water than seems necessary. Be finished by nine-thirty, or come back at six.

Do that and summer here is a genuinely good time to visit. Ignore it and you will not come back.
