The country is small enough that most itineraries cross climates rather than staying in one. Pack for the range, not the average.
Clothes
Light layers for the coast and the capital, and one genuinely warm layer for the highlands after dark. The coffee towns sit high and the evening drops further than a first time visitor expects. A light rain layer earns its space in the wet half of the year, when the afternoon burst is heavy and brief.
Shoes, and this is the one that matters
The colonial towns are cobbled, and Salvadoran cobbles are large, rounded and uneven rather than flat. Suchitoto is beautiful and it is hard walking. Bring a shoe with a real sole and an ankle you trust, and if you intend to walk on a volcano bring something that can cope with loose volcanic grit, which behaves like gravel on a slope.
Sun
The coastal plain and the volcanic high ground are both unforgiving, for different reasons. A hat, sunglasses and a high factor sunscreen are not optional, and the altitude makes the highland sun stronger than the temperature suggests.
⚠ Water
The cited advice records a risk of contaminated drinking water, and that bottled water is inexpensive and widely available. Plan around bottled or treated water for drinking and for brushing your teeth. A refillable bottle and a means of treating water is lighter than the alternative and produces less waste.
The same advice records that rivers tend to be contaminated and are unsafe to swim or bathe in. That is worth knowing before a hot afternoon beside a very inviting one.
Insects
Mosquito bite avoidance matters here regardless of what tablets anyone is or is not taking. Repellent, long sleeves at dawn and dusk, and a room you can close up are the practical measures, and they cover several risks at once.
Documents and money
A photocopy of your passport and entry stamp, kept separately from the originals. Small denomination US dollars. A card you have told your bank about. And your insurer's emergency number written down somewhere that does not need a charged phone.
What to leave
Expensive jewelry and anything you would be distressed to lose. The cited advice asks visitors not to wear expensive clothing or jewelry, and to pack as light as they can and leave at home any item they could not replace. It is a small country and a modest bag is genuinely easier in it.
The weather guide in this cluster explains why the list looks the way it does, and the accessibility guide explains why the shoes matter more here than the clothes.
