Question 1

When is the rainy season in Havana?

Accepted Answer

Havana's rainy season runs from May through October, when the city receives the vast majority of its annual rainfall. During this six-month stretch in 2025, Havana recorded 1,004.4 mm (39.5 in) of precipitation — about 75% of the city's full-year total of 1,337.4 mm (52.7 in).

September 2025 was by far the wettest month in Havana, with 351.7 mm (13.8 in) of rain and average humidity of 82.7%. August and October were also notably wet, delivering 220.9 mm (8.7 in) and 157.6 mm (6.2 in) respectively. Across the rainy season, Havana averaged 27.4°C (81.3°F), so showers tend to arrive as warm afternoon and evening downpours rather than all-day rain.

By contrast, the dry season from November through April is much more settled. These months saw just 333.0 mm (13.1 in) combined in 2025, and January was the driest month of all with only 16.8 mm (0.7 in) of rainfall.

If you want to avoid Havana's heaviest rains, the dry season — especially December through April — is the most reliable window for sightseeing, beach trips, and outdoor activities. Travelers visiting during the wet months should plan around midday and early-evening storms, which are usually brief but intense, while still enjoying plenty of sunshine between showers.

Question 2

What were the temperature extremes in Havana in 2025?

Accepted Answer

In 2025, Havana's temperatures ranged from a low of 14.2°C (57.6°F) to a high of 35.1°C (95.2°F), giving the Cuban capital an annual swing of roughly 21°C (37.6°F) between its coldest night and hottest afternoon.

The hottest day in Havana in 2025 came on **August 9**, when the temperature peaked at 35.1°C (95.2°F). The coolest reading was recorded on **March 12**, when the thermometer dipped to 14.2°C (57.6°F) overnight. Across the full year, the average temperature settled at a warm 25.6°C (78.0°F), with typical daily highs near 29.6°C (85.3°F) and overnight lows around 21.9°C (71.5°F).

These extremes reflect Havana's tropical climate, where heat is the dominant story rather than cold. The city logged 183 days with highs of at least 30°C (86°F) in 2025, and 29 of those days reached 33°C (91°F) or hotter. August was the warmest month overall at 28.2°C (82.8°F), while January was the coolest at 22.1°C (71.8°F).

For visitors, this means Havana stays comfortably warm year-round, so light clothing is suitable in every season. The narrow temperature range makes the city a reliable warm-weather destination, though the peak summer months bring the most intense heat and humidity, best managed with shade, water, and midday breaks.

Question 3

What is the sunniest time of year in Havana?

Accepted Answer

The sunniest time of year in Havana falls in mid-summer, with August and July recording the most sunshine in 2025, though spring offers the best mix of sun and dry weather. Across the full year, Havana enjoyed roughly 3,200 hours of sunshine, averaging about 8.8 hours of sun per day.

In 2025, August led with 348.5 sunshine hours and July followed closely with 346.6 hours — both delivering around 11.2 hours of sunshine per day. These peak summer months, however, came with heavy rain: August alone saw 220.9 mm (8.7 in) of precipitation, so bright spells were often broken by afternoon downpours.

For consistent sunshine without the heavy rain, spring (March to May) stands out. Havana averaged 307 sunshine hours per month across these three months, peaking at 319.1 hours in May, while monthly rainfall stayed low at about 53 mm (2.1 in) on average. The least sunny month was October, with just 193.3 hours.

This pattern means the brightest raw sunshine in Havana arrives in the hot, humid summer, but visitors chasing reliable sun are usually better served by the spring window. With warm averages near 25–27°C (77–81°F) and abundant light, March through May combines plenty of sunshine with comfortable, drier conditions ideal for sightseeing and beach days.

Question 4

What are the average summer temperatures in Havana in 2025?

Accepted Answer

Havana enjoyed warm, consistently hot summer temperatures in 2025, averaging **27.9°C (82.2°F)** across the meteorological summer (June 1 to August 31).

For visitors, summer 2025 in Havana meant steady heat with little day-to-day variation, ideal for beach trips and water activities. The high humidity and frequent afternoon showers, however, made early mornings and evenings the most comfortable times for sightseeing and outdoor exploration.

Question 5

How humid is Havana throughout the year?

Accepted Answer

Havana is consistently humid all year, with an average relative humidity of around **77%** across 2025. As a coastal Caribbean city, Havana rarely dips into dry conditions, even in its more comfortable months.

Humidity in Havana peaked in **September 2025 at 82.7%**, the most oppressive point of the year, and stayed high through October at 81.0%. The driest stretch came in spring: **April 2025 was the least humid month at 69.7%**, with March close behind at 71.0%. That gives Havana a fairly narrow annual swing of just **13 percentage points** between its most and least humid months.

Grouped by meteorological season, the pattern is clear:

- **Spring (March–May 2025):** ~71.8% — the most comfortable
- **Summer (June–August 2025):** ~77.3%
- **Autumn (September–November 2025):** ~80.4% — the muggiest season

The autumn humidity spike in Havana lines up with its wettest period, including 351.7mm of rain in September 2025, when warm 27°C (81°F) air holds large amounts of moisture. For travelers, this means the early-year months of March and April 2025 offered the most pleasant, drier-feeling conditions, while late summer and autumn felt sticky and sultry. Lightweight, breathable clothing and good hydration are advisable year-round in Havana, but especially from September onward when the combination of heat and humidity is most intense.
