Month by month
4°C / -2°C · 12 rain days · 4.0 h sun
Days stay cold, with highs around 4°C and lows near -2°C. Rain or snow falls on about 12 days, and sunshine is scarce at just 4 hours a day. This month scores low, and January 1 is a public holiday, so expect quiet streets but also short, dim days.
7°C / -1°C · 10 rain days · 5.8 h sun
Highs reach about 7°C, with lows just below freezing at -0.9°C. There are around 10 rain or snow days, though sunshine picks up slightly to 5.8 hours daily. The month still scores poorly for a visit, mostly because of the cold and grey skies.
10°C / 1°C · 10 rain days · 7.7 h sun
Temperatures climb to a 10°C high and 1°C low, with rain on about 10 days. Sunshine rises to 7.7 hours, a clear improvement over winter. The score still lands in the weak range, as early spring weather can swing between mild and chilly.
15°C / 4°C · 10 rain days · 9.6 h sun
This is where conditions turn favourable, with highs of 15°C and lows of 4°C. Rain falls on about 10 days, but sun hours jump to 9.6. Easter weekend, with Good Friday on April 3 and Easter Monday on April 6, adds a cultural reason to visit during this good-scoring month.
20°C / 9°C · 12 rain days · 10.7 h sun
Highs reach 19.5°C and lows 9°C, making for pleasant, mild conditions. Rain days rise to nearly 12, with 66mm of rainfall, so pack a light rain jacket. Sunshine is strong at 10.7 hours, and the month scores among the best of the year, helped by Labour Day on May 1 and Liberation Day on May 8.
25°C / 14°C · 12 rain days · 12.3 h sun
Summer heat arrives, with a 25°C high and 14°C low. Rain is frequent, with almost 12 rainy days and 75mm total, often from short thunderstorms. Sunshine hits 12.3 hours daily, and this month ranks among the best for visiting.

Conditions turn tougher, with highs of just 8.5°C and lows of 2°C. Rain falls on about 10 days, and sunshine drops to 4.3 hours, among the lowest of the year. The month scores poorly for weather, though Struggle for Freedom and Democracy Day on November 17 marks a key national holiday.
