Frequently Asked Questions

Store in Celsius (metric) as the source value and derive Fahrenheit for display. Never store the same temperature in multiple units — the derived value will drift if the source is ever corrected.

Current conditions: every 10-30 minutes. Hourly forecast: every hour. Daily forecast: every 3-6 hours. Cache aggressively — weather APIs charge per call and conditions change slowly.

Use null for fields that the station did not report (uvIndex, precipMm). Do not omit the field — the client should know the field exists but has no data, rather than treating missing as 0.
