Bukavu weather history

24 of the last 24 days were warmer than the historical normal for that date. Average difference: +1.9°C.

Each bar is one day, from morning low to afternoon high. Warm-colored bars are days whose mean ran above normal; cool bars ran below. The dot inside the bar is the daily mean. The shaded band is the typical 10–90% range expected for that date. Normal = the day's mean temperature averaged across every year of record (1940–2026) for that calendar date.

August is the warmest month, December the coolest — a yearly swing of 1°C.

Each bar is the average daily low → average daily high for that month. Color shifts cool→warm by month temperature. The dot is the monthly mean. Normal = each month's value averaged across every year of record (1940–2026).

Wettest month: November (~335 mm). Whole year averages ~2318 mm of rain.

Average total millimetres of rainfall in each calendar month, across the full record.

Average daily peak wind at 10 m, by month.

Average daily incoming solar energy in megajoules per square metre — a measured proxy for how sunny the month is.

Numerical reference: average highs/lows, mean rainfall, and absolute records for each month of the year. Normal = each month's value averaged across every year of record (1940–2026).

Annual mean shifted from 1940–1949 to 2016–2025 by +1.5°C.

Each vertical stripe is one year. Color encodes how much that year's annual mean differed from the long-term average. Normal = each year's annual mean compared to the average of all years (1940–2026). cooler ← → warmer

Days ≥ 25°C per year: 28.6 early in the record → 95.9 recently. Frost days: 0 → 0.

Thin lines are raw yearly counts; thick lines are the smoothed trend that removes year-to-year noise. The hot-day threshold is auto-picked per city so the line actually moves. Normal = a centered 5-year rolling average to smooth weather noise.

All-time high in 1997, all-time low in 1960: 29.8°C / 9.4°C.

One point per year — the single hottest and coldest day recorded that year.

~2318 mm/year on average. Last decade ran −4% vs that average.

One bar per year of total rainfall. Dashed line is the long-term average. Normal = the average annual rainfall across every year of record (1940–2026).

Each tiny square is one calendar day across the full record — ~30,000 days per city. Use the mode switch above the chart: Anomaly colors each day by how far it ran from the historical normal for that date (red = warmer, blue = cooler), Daily mean temp shows the absolute mean temperature for the day (useful to see seasons and heatwaves), and Precipitation shows daily rainfall (useful to spot wet/dry seasons and droughts). Normal = the long-term average for that calendar date (1940–2026).
