Monthly weather averages & travel planning

Updated: March 2026
February is a fair time to visit Busan (5/10). With 9 daily sunshine hours and only 5 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 3rd sunniest of the year in Busan. Culture-focused travellers and those who prefer lighter crowds will find February a practical choice, with prices running lower than peak April without sacrificing all the good weather. March offers a similar profile at lower hotel rates if dates are flexible. The 8°C highs require proper cold-weather clothing; many visitors underestimate how far the wind chill drops the perceived temperature, particularly near water or at elevated viewpoints. 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 Busan in February: conditions are genuinely cooperative, with 8°C highs and only 5 wet days making this one of the more straightforward months to plan around. Precipitation totals 43mm for the month, spread across roughly 5 days, and 9 sunshine hours per day give you a reliable window for outdoor plans.

The 7°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. Humidity averages 65%, which is comfortable for most visitors. On warmer days, lighter fabrics help with the mild stickiness in the afternoon. The UV index of 2 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Wind averages 19 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 46°F average high, 34°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Busan in February means dressing for 8°C days and 1°C evenings. Layering is key: a thermal base, mid-layer fleece, and a windproof outer jacket for 8°C highs that feel colder in the wind. Evening temperatures settle at 1°C, a modest 7°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Busan's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.
February has no major festivals or public holidays in Busan, 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 8°C average highs and 5 rainy days
February in Busan reflects a mid-latitude climate pattern, with temperatures averaging 8°C by day and 1°C overnight. The city sits at 35 degrees north latitude, where the balance between solar radiation and heat loss drives conditions that are neither extreme nor static. Cold conditions reflect the dominance of polar or continental air masses, which bring dry, stable weather with low humidity. Day-to-night temperature variation of 7°C is moderate and manageable with a single mid-layer. 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.
