The Wikipedia "Read more →" link in the notable-weather section could break
between "Read" and "more" at narrow widths. Join it with non-breaking spaces so
it stays on one line.

The per-month records section listed only the warmest and coldest temperature.
Extend it to a card per metric (High, Low, Feels-like, Humidity, Wind, Gust,
Precip), each showing that calendar month's record high and low with the date.
Precip is special-cased: a per-day record low is just zero, and the dry-streak
helper would bridge year boundaries on month-filtered rows, so the wettest and
driest sides use the month's largest and smallest total accumulation, dated to
the year. Partial current months (< 26 days) are excluded so an unfinished month
can't win "driest" on a fraction of its rainfall.
Reuses the records page's card grid, so it's already vertical on mobile.

The month and season records tables showed only the record high (of the daytime
high) and the record low (of the overnight low) — one extreme each. Show both
ends of both metrics: for the daytime high, its record hottest (▲) and the
coldest a day ever stayed (▼, its record-low high); for the overnight low, its
mildest night (▲, its record-high low) and its record low (▼). All four already
came out of all_time_records; they were just being dropped.
Restructure each table to Period · Daytime high · Overnight low, with each metric
cell carrying two tinted, dated chips (▲ warmest / ▼ coldest). Fits mobile in
three columns; the all-time cards already showed both extremes, so this brings
the per-period tables in line.
The monthly temperature-range visualization now spans the 10th-percentile daily low
to the 90th-percentile daily high (from climatology's p10/p90) — the band most days
fall within — instead of just the average low to average high, giving a truer sense
of each month's spread. The normals table keeps the average high/low figures.
Add a search box to /climate that filters to a flat, alphabetical list of matching
cities (by city or country name), shown with their country; clearing it restores the
collapsible directory. The index is built from the already-crawlable links, so it's
a pure progressive enhancement (no SEO impact). Also sort cities alphabetically
within each country in the directory (were population-ordered).
Two mobile polish issues on the climate pages:
- The season records table's "(Dec–Feb)" span overflowed its narrow first
column (nowrap) and slid under the tinted value cell. Stack the span under the
season name on phones, top-align the record cells, and let the first column
wrap — so the period label sits cleanly in its own column.
- The monthly temperature-range strip stretched edge-to-edge with the values
floating far to the right. Cap the strip width so bars + values pack into a
tight group, shrink the value labels to fit (compact "41°–66°", no reserved
92px column). The overrides now sit after the base range rules so they win.
The all-time-records redesign (#106) removed the min-width floor that let the
wide records tables scroll, so the month and season records tables — still five
columns (value + separate date, twice) — compressed below their content on
phones and overlapped/clipped.
Fold each record's date under its value so those tables become three columns
(period · record high · record low), which fit any width without horizontal
scroll. Also tighten all climate tables under 560px (smaller font + padding) so
a hot city's 3-digit °F values with °C in parens never collide in the city
page's normals table.
* SEO: monthly & seasonal records on the city records page
The /climate/<city>/records page showed only all-time records per metric.
Expand it into a full records page: record high/low for each of the 12
months (each linking its month page) and for each meteorological season,
alongside the existing all-time table.
Seasons are hemisphere-aware — Dec–Feb reads as winter for northern cities
and summer for southern ones (picked from the city's latitude). Records
reuse grading.all_time_records over a month-filtered archive, so no new
data fetching or warming is needed. Adds a Dataset + breadcrumb JSON-LD
block and richer title/description for the expanded coverage.
* SEO: colour-code climate & records pages (heat-map + range strip)
The city, records and month pages were plain muted tables — generic climate-site
styling. Bring the interactive grader's diverging cold→hot palette onto them so
they read as heat maps in the site's own visual language:
- Map absolute °F to the 9-tier palette (temp_class, a Jinja global) and tint the
temperature cells across the monthly-normals, monthly/seasonal/all-time records
tables. The value stays in the ink token; the tint is a wash behind it. Non-temp
rows (humidity/wind/precip) and date columns stay untinted.
- Add a monthly temperature-range strip on the city page: one gradient bar per
month spanning the average low→high on a shared −10..115°F axis, so a city's
whole-year rhythm (and hot-vs-cold character) reads at a glance.
- Tint the month page's hero high/low and its record values inline.
Palette, light/dark, and 390–1920px layouts verified by rendering hot (Phoenix)
and cold (Anchorage) cities.
Replace the 5-column records table (which forced horizontal scrolling on mobile —
only high OR low visible) with a responsive card grid: one card per metric, each
with a red-accented 'Highest' row and a blue-accented 'Lowest' row (tier colors).
Grids on desktop, stacks to a single column on mobile with high/low stacked
vertically — no horizontal scroll. Precip reads Wettest / longest dry spell.
Record-low rainfall is meaningless (always ~0), so the precip row's low side now
shows the longest run of consecutive days without measurable rain and the date that
dry spell began (grading.longest_dry_streak), keeping the wettest day on the high
side. A footnote explains the substitution.
Drop the open-by-default on the first three countries (every <details> starts
collapsed) and order the country sections alphabetically instead of by largest
city's population.
- Climate hub (/climate) now uses native <details> per country — collapsible
expand/shrink sections with a city count and a rotating marker (top 3 countries
open by default). Links stay in the DOM, so crawling/SEO is unaffected.
- Fix nested F/C parentheses in the city lede (e.g. 'July (71°F (22°C) average
high)') by rephrasing so the already-parenthesized temperature isn't wrapped in
another paren.
- Fix the 5-column records table overlapping on mobile: give it a min-width so it
scrolls inside .table-wrap on narrow screens instead of colliding.
Auto-sourcing a notable weather event from Wikipedia search proved unreliable
(wrong matches, low coverage), so city_events.py is a small, fact-checked list of
one iconic event per city (Katrina/New Orleans, Harvey/Houston, the 1952 Great
Smog/London, the 2021 heat dome/Seattle, ...) — 31 cities, each with a Wikipedia
link. The city page shows a 'Notable weather in {city}' callout when one exists and
otherwise just the flavor blurb. Tests check the curated slugs are all valid and the
callout renders (and is absent for uncurated cities).
Add unique editorial content so the programmatic pages don't read as templated:
- gen_flavor.py seeds backend/cities_flavor.json with a short descriptive blurb per
city from Wikipedia's free REST summary API (no key), validating each match by
comparing article coordinates to the city's lat/lon so the wrong 'Springfield'
never attaches. Retries + modest concurrency; ~700/750 cities get a blurb, the
rest render without one. Text is CC BY-SA, attributed with a 'via Wikipedia' link.
- City pages show the blurb under the intro and a travel callout that deep-links to
the compare page with the city pre-loaded (/compare#loc=lat,lon) — the visitor
just adds their own city. Month pages get the same seasonal 'visiting in {month}?'
compare link. Both add unique per-page text and internal links.
- cities.py gains flavor(slug); tests cover the blurb + attribution + compare CTA.
* SEO: generate curated city set for crawlable climate pages
gen_cities.py reuses the GeoNames index places.py already parses to select the top
~500 metros by population, assigns each a stable URL-safe slug (dropping admin1 when
it repeats the city name), and writes committed backend/cities.json. cities.py loads
it lazily with slug lookup, all_slugs(), display_name(), and by_country() grouping
for the upcoming hub + sitemap.
* SEO: rendering core, robots.txt, sitemap.xml, and metadata hygiene
- content.py: Jinja2 environment + HTML responder (ETag/304), dynamic /robots.txt
(disallows /api and /alerts, points at the sitemap) and /sitemap.xml (enumerates
the home/static pages plus every city, month, and records URL from cities.py).
Registered on the app before the StaticFiles mount so the routes win.
- templates/base.html.j2: shared layout with unique title/description, self-
referential canonical, Open Graph, favicon/manifest, header nav (adds a Climate
link) and a footer link graph.
- Give each existing page a unique <meta description> (were 5x identical) and a
self-referential <link rel=canonical>; add WebApplication JSON-LD to the home page.
- Pin jinja2.
* SEO: server-rendered per-city climate page (/climate/{slug})
The keystone crawlable page: for a city it snaps to the grid cell, loads the
archive (fetching once if missing, self-healing), and renders as real HTML — a
'how today compares' block (grade + percentile per metric from grade_day, tinted
by tier), a monthly normals table (climatology at each month's 15th, shown in °F
and °C), all-time records (new grading.all_time_records helper), a breadcrumb,
Dataset+Place+BreadcrumbList JSON-LD, self-referential canonical, and links into
the interactive tool + month/records pages. Content-page CSS added to style.css
(renamed the table class to avoid colliding with the app's .normals flex row).
* SEO: month (/climate/{slug}/{month}) and records (/climate/{slug}/records) pages
Month pages render the exact-month long-tail ('average weather in {city} in
{month}') with that month's average high/low, typical p10-p90 range, month-specific
records, and prev/next month links. Records pages show all-time record highs/lows
per metric with dates (grading.all_time_records). Shared _resolve_city helper; the
literal /records route is registered before the {month} param and month names are
validated (unknown month -> 404).
* SEO: climate hub, weather glossary, and about/methodology pages
- /climate: crawlable directory of all ~500 cities grouped by country — the
internal-link graph that lets search engines discover every city page.
- /glossary + /glossary/{term}: plain-language definitions (climate normal,
percentile, temperature anomaly, feels-like, heat index, wind chill, humidity,
reanalysis) with DefinedTerm JSON-LD and cross-links into the tool.
- /about: methodology page (ERA5 data source, 45-year baseline, +/-7-day window,
percentile grading) for E-E-A-T. All linked from the shared footer.
* SEO: archive warmer, content-page tests, and deploy docs
- warm_cities.py: paced, idempotent offline warmer that pre-fetches each city
cell's archive so /climate pages serve from cache and a crawl can't burst the
archive quota (pages self-heal if hit before warming).
- tests/test_content.py: city-set slug uniqueness/lookup, robots.txt, sitemap
enumerating city/month/records URLs, and that a rendered city page carries the
stats + canonical + Dataset JSON-LD in the HTML; plus month/records/hub/glossary/
about routing and 404s.
- DEPLOY.md: document the content pages, the warm step, and submitting the sitemap.
