Is May Right for You?

Advantages

Perfect dry season weather with 31°C (88°F) highs and minimal rainfall - ideal for exploring volcanoes and archaeological sites without muddy trails
Low tourist season means shorter lines at Joya de Cerén and Tazumal, plus accommodation rates 25-30% lower than December-March peak

Optimal conditions for volcano hiking - clear morning visibility at Cerro Verde and Izalco before afternoon cloud cover rolls in around 2pm

Considerations

Limited evening cooling - temperatures only drop to 21°C (69°F) at night, making non-air-conditioned accommodations stuffy
UV index of 8 requires constant sun protection - sunburn happens within 15 minutes of unprotected exposure at higher elevations

Essential Tips

What to Pack

SPF 50+ sunscreen and reapplication every 2 hours - UV index 8 causes burns within 15 minutes at volcano elevations above 1,200m (3,937ft)

Lightweight long-sleeve shirts in light colors - protects from sun while staying cool in 70% humidity

Sturdy hiking boots with good grip - volcanic rock trails at Cerro Verde and Santa Ana can be slippery even when dry

Quick-dry shorts and pants - even without rain, morning dew and high humidity create dampness on trails

Wide-brimmed hat or cap - essential for volcano hikes where shade is minimal above tree line at 1,500m (4,921ft)

Lightweight rain jacket - despite low rainfall, occasional 20-minute afternoon showers occur on 10 days in May

Electrolyte packets or tablets - high humidity and heat increase dehydration risk, especially during physical activities

Moisture-wicking underwear and socks - synthetic or merino wool materials handle 70% humidity better than cotton

Portable battery pack - phone batteries drain faster in high heat, crucial for GPS on volcano hikes and translation apps

Insect repellent with DEET - May warmth increases mosquito activity, especially near Lake Coatepeque and coastal areas

Insider Knowledge

Start volcano hikes at 7am sharp - after 11am, heat and UV become dangerous, and afternoon clouds block crater views by 2pm. Local guides refuse afternoon Santa Ana hikes in May.

Eat at pupuserías between 5pm-7pm when locals dine - prices are lowest ($0.75-1.25 per pupusa), food is freshest, and you'll experience authentic atmosphere without tourist markups

Book accommodation in Zona Rosa or Escalón with reliable air conditioning - many budget places advertise AC but only run it limited hours due to electricity costs averaging $0.20/kWh

Exchange money at Banco Agrícola or Banco de América branches for best rates (typically $1 = $1 at 1-2% fee) - avoid hotel exchanges that charge 8-10% commission on US dollars

Avoid These Mistakes

Planning volcano hikes after 10am - May heat makes afternoon hiking dangerous, and clouds obscure views. Most tour operators won't take clients up Santa Ana crater after 11am for safety reasons.

Booking beachfront accommodations without air conditioning - May nights only cool to 21°C (69°F) with 70% humidity, making sleep uncomfortable in fan-only rooms

Underestimating sun exposure time - UV index 8 at sea level increases to 10+ at volcano elevations. Tourists frequently get severe sunburns during 4-6 hour outdoor activities
