Monthly weather averages & travel planning

South America › 🇵🇪 Peru › Lima
Updated: March 2026
March is a good time to visit Lima (7/10). With 11 daily sunshine hours and only 7 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 5th sunniest of the year in Lima. Culture-focused travellers and those who prefer lighter crowds will find March a practical choice, with prices running lower than peak September without sacrificing all the good weather. February offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Lima's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
Based on 30-year climate normals (1991 to 2020), March in Lima averages 26°C by day and 21°C overnight, a range that places it firmly in the warmer tier of the annual calendar. The month records approximately 11 sunshine hours per day and 22mm of total rainfall across 7 wet days, giving it a sunshine-to-rain ratio that is decidedly favourable for outdoor travel.

The narrow 5°C gap between daytime and overnight temperatures, characteristic of coastal cities with maritime moderation, means a single mid-layer works across the whole day. At 82% humidity, the 26°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Winds are calm at an average 14 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 79°F average high, 70°F overnight low.

Packing for Lima in March means dressing for 26°C days and 21°C evenings. A light cotton tee with a casual overshirt works well at 26°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 21°C, a modest 5°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Layers are more practical than a single heavy garment in Lima. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
March has no major festivals or public holidays in Lima, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 26°C average highs and 7 rainy days
Lima's March climate is governed by the Inter-Tropical Convergence Zone (ITCZ), which draws moisture-laden trade winds across the region, producing the characteristic wet season rainfall of warm tropical cities. Daytime heat peaks around 26°C, moderated slightly by afternoon convective showers. Overnight temperatures remain warm at 21°C because the humid air retains heat effectively. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
