Monthly weather averages & travel planning

North America › 🇲🇽 Mexico › Mexico City
Updated: March 2026
April is a good time to visit Mexico City (6/10). With 12 daily sunshine hours and only 10 rain days, this month delivers genuinely reliable outdoor conditions, ranking it the sunniest month of the year in Mexico City. Culture-focused travellers and those who prefer lighter crowds will find April a practical choice, with prices running lower than peak April without sacrificing all the good weather. May offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Mexico City'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.
The single most important thing to know about visiting Mexico City in April: the gap between the 25°C daytime high and the 11°C overnight low is large enough to catch underprepared visitors off guard, so layers are non-negotiable. Precipitation totals 49mm for the month, spread across roughly 10 days, and 12 sunshine hours per day give you a reliable window for outdoor plans.

The 14°C day-to-night swing is large enough to require a deliberate layering strategy, what works at noon will be noticeably cold by 10pm. At 78% humidity, the 25°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. Wind averages 15 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 77°F average high, 52°F overnight low.

Packing for Mexico City in April means dressing for 25°C days and 11°C evenings. A light cotton tee with a casual overshirt works well at 25°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 14°C to around 11°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 10 potential rainy days. At 78% 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 Mexico City. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
April has no major festivals or public holidays in Mexico City, 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 25°C average highs and 10 rainy days
In April, Mexico City sits in the dry season corridor, as the ITCZ shifts away from the region and trade winds bring drier, more stable air. This produces reliably sunny days reaching 25°C, with lower humidity than the wet months. Overnight lows of 11°C offer a pleasant reprieve from the midday heat. 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.
