A “hot day” is any day above 31.4°C. Drag to see the rule change what it counts.

26°C35°C

22 of 31 days in Jul 2026 qualify.

Those 31 days collapse into three numbers. That is the whole of what “a month” means on this site:

Add them up: 227.5 mm; Total rainfall. This is the value the Rainfall fingerprint paints for Jul 2026.
Average them: 32.1°C; Mean daily high — not the hottest day, the typical one.
Count them: 22 days; Days over the threshold. A count, so one very hot day counts the same as any other.

Checked against the stored record: the grid below holds 227.5 mm and 32.1°C for Jul 2026. Those are the same three operations on the same days, so they match what is shown above exactly — verified for all 90 cities, not assumed. Multiply this by 12 months and 77 years and you have the fingerprint.

Your baseline

Since 1950, Langsa’s average daily high has moved +1.0 °C.

Compare against1950–2006

An endpoint comparison, not the fitted trend in “what moved most” above — the two answer different questions and will not agree. This compares the 10-year mean starting at your baseline against the last 10 complete years (2016–2025), using monthly average daily maximum. Both ends are decade means so one strong El Niño cannot pass for a trend. Baselines after 2006 are not offered — too few years remain for the comparison to mean anything.
