The wettest month in this station normal is January at 47.2 mm. July averages 5.0 mm. Low annual rain does not establish that a property is free of drainage problems. Ask about the entrance and roof during a viewing.1

The normal records about 4.5 January days and 1.3 July days with at least 1 mm of rain. This definition differs from a day with any trace of rainfall.1

Inspect the home for both seasons

  • Check coolingConfirm the equipment, room coverage and power requirements before summer.
  • Check heatingAsk which rooms are heated and inspect the recent winter bills.
  • Inspect windowsConfirm closing mechanisms, drafts and shading in the actual apartment.
  • Inspect drainageAsk about past leaks and the building's maintenance responsibilities.

Use Rent for the viewing checklist and Utilities for property bill questions. The rental average does not tell you whether a particular room stays comfortable.

What should you do during Zonda winds?

Provincial Civil Protection advises limiting outdoor exposure, closing windows and staying away from fragile trees or damaged cables during Zonda. It also advises against fire-risk activities. Follow the current warning and local instructions.2

  1. Review the warning

    Read the actual provincial notice before setting off.

  2. Secure the home

    Close windows and secure loose items as advised.

  3. Change the route

    Avoid exposed trees, cables and unnecessary outdoor travel.

  4. Recheck the excursion

    Ask the operator about current mountain and road conditions.

The Safety page covers preparing an ordinary routine. The Weekend trips page explains why a city weather chart cannot settle mountain access.

Use a trial stay to answer the housing question

Spring and autumn normals offer a different temperature pattern from peak summer and winter. October averages a 25.7°C daily high and an 11.9°C low. April averages 23.3°C and 10.8°C. Neither establishes weather on a particular date.1

A trial stay is most useful when you inspect the conditions you expect to handle year round. Use Families for school journeys and Remote work for comfort during daytime calls.
