Month by month
8°C / 0°C · 8 rain days · 5.8 h sun · sea 9°C
Burgas highs reach just 7.8°C with 8.2 rain days and only 5.8 hours of sun a day. The sea sits at 9°C, so this is a cold, grey month with a score of 2.7 — a tough time weather-wise. New Year's Day and Currency Change Day fall now, but this is really a month for ski resorts inland rather than the coast.
11°C / 2°C · 7 rain days · 6.9 h sun · sea 7°C
Temperatures climb slightly to a 10.6°C high, with 6.8 rain days and 6.9 hours of sun. The sea stays cold at 7°C. The score rises to 4 (ok) — still chilly, but drier than January, making it decent for city breaks rather than beach time.
13°C / 4°C · 9 rain days · 8.0 h sun · sea 9°C
Highs reach 12.7°C with 9.3 rain days, the wettest count so far. Sun hours rise to 8 and the sea warms a touch to 8.8°C. The score of 5 (ok) reflects a transitional month. Liberation Day on March 3 is a public holiday worth knowing about if you're travelling then.
17°C / 7°C · 9 rain days · 10.2 h sun · sea 12°C
Spring arrives properly: highs of 17.2°C, 9 rain days and 10.2 hours of sun daily. Sea temperature reaches 12.2°C, still too cold for swimming. The score jumps to 6.9 (good). Easter falls in April, with Good Friday through Easter Monday all public holidays.
21°C / 12°C · 11 rain days · 12.0 h sun · sea 16°C
