Considerations

Afternoon thunderstorms occur 10 days per month, typically 2-4pm, lasting 30-45 minutes but can disrupt outdoor lunch plans and beach time
Higher humidity at 70% makes midday hiking and strenuous outdoor activities feel more challenging than temperature suggests
Some restaurants and small businesses reduce hours or close for annual maintenance during this quieter tourism period

Essential Tips

What to Pack

Quick-dry lightweight rain jacket - afternoon storms last 30-45 minutes with heavy droplets, temperatures stay warm at 26°C (79°F)

Moisture-wicking cotton or bamboo shirts - avoid polyester in 70% humidity as it traps heat and feels clammy

SPF 50+ reef-safe sunscreen - UV index reaches 8 and reflects off white sand beaches and water

Grippy hiking shoes with drainage - trails stay muddy 2-3 days after rain, rocks become slippery

Wide-brimmed hat with chin strap - sudden wind gusts up to 25 knots can blow caps away

Waterproof phone case - essential for boat trips and sudden downpours, protects camera during water activities

Electrolyte tablets - humidity makes dehydration sneaky, local water is safe but bring backup hydration

Light merino wool or synthetic sleepwear - evening temperatures drop to 26°C (79°F) with trade wind cooling

Packable day bag with waterproof zippers - protects electronics and documents during unexpected showers

Insect repellent with 20% DEET - mosquitoes emerge after rain showers, especially near mangroves and wetlands

Insider Knowledge

Local buses ($1.50 EC) run more frequently in August due to school schedules - most reliable transport month with 15-minute intervals on main routes

Restaurants offer 'hurricane season' specials throughout August with 25-30% discounts on multi-course meals - ask about resident rates even as tourists

Morning fish markets (5:30am-7:30am) in St. Johns have best selection as fishing boats return from overnight trips in calmer conditions

Trade winds create natural air conditioning - book accommodations on east-facing slopes for constant cooling breezes and lower AC costs

Avoid These Mistakes

Planning beach days from 1-4pm when thunderstorms are most likely - morning and late afternoon offer better conditions

Booking only outdoor activities without indoor alternatives - afternoon weather can disrupt plans despite sunny morning forecasts

Underestimating hydration needs because temperatures feel moderate - 70% humidity causes faster fluid loss than visitors expect
