National figures need local context
Météo-France’s 3 September review identifies summer 2026 as France’s hottest since 1900, with a +3.6°C temperature anomaly and 53 days of heatwaves. The national rainfall shortfall was close to 40%.
Its detailed report adds a crucial regional distinction: seasonal rainfall in PACA was close to normal because of thunderstorms. National averages cannot describe a particular Riviera address. A near-normal rainfall total does not guarantee comfortable bedrooms on hot nights.
Inspect the home across a full day
Replace a general question about heat with five practical checks:
- Sun exposure: which rooms heat up after midday, and do external shutters and terrace shade actually help?
- Night ventilation: can bedrooms be aired without opening onto intrusive street noise? Is cross-ventilation possible?
- Roof: for a top-floor apartment, request insulation details and roof-work records.
- Cooling: check equipment servicing, condensate drainage and outdoor-unit noise.
- Bills: compare summer expenditure with occupancy, usage and the applicable tariff.
The previous owner’s bill is a starting point, not a forecast of your spending. An empty second home and a continuously occupied apartment have different energy profiles.
Check permissions before budgeting alterations
An installed air-conditioning unit is not proof that all permissions were obtained. Request relevant co-ownership resolutions and planning approvals. Verify proposed new units, awnings and external shading before treating them as straightforward renovation items.
For a villa, add drainage, crack history and address-specific natural risks to the checklist. Check current water restrictions and fire-prevention requirements locally. A climate report cannot replace these checks; our clay-soil guide covers a separate part of the assessment.
Budgeting for summer comfort
Comfort, remedial works and running costs belong in your property budget. A claim that the summer changed insurance premiums, demand or prices in departments 06 and 83 requires local evidence. This article establishes no measured market effect. The useful output is a property-specific list of documents and costed improvements.
