Priority fixes for weawow.com

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   TLS 1.3 negotiated

   Observed: The TLS connection negotiated TLSv1.2.

   Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.

   What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.

   88% of Weather Forecast peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 3 external scripts without async or defer.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   56% of Weather Forecast peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 44 images and none used WebP or AVIF.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   23% of Weather Forecast peers do this.

4. Priority 4 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 44 images and none used loading="lazy".

   What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.

   50% of Weather Forecast peers do this.
