Virginia has a statute, not a threshold table. A 2025 law makes heat policy mandatory for every school board in the Commonwealth — and then leaves the actual WBGT levels to each district, which is why no honest page can tell you Virginia's cancellation number.
Code of Virginia § 22.1-271.10 (2025, cc. 478, 493) directs the Board of Education to develop and biennially review heat guidelines, and then requires each school board to adopt its own policies in line with them.
The law tells districts what their policy must contain, not what the numbers are. District policies must "Include parameters relating to the scheduling of outdoor athletics practices or games during different WBGT levels and establishing the WBGT levels at which outdoor athletics practices or games shall be cancelled" — so the WBGT level at which your practice is cancelled is a decision your school board made, and the only place to read it is your division's own policy.
District policies must also "Be consistent with any heat guidelines based on Wet Bulb Globe Temperature (WBGT) levels developed by an organization or entity whose purpose it is to regulate or govern interscholastic athletics programs in the Commonwealth" — in practice, the VHSL's WBGT-based guidance. VHSL's own rule is advisory; the statute is what makes a local policy mandatory.
Every district policy must include a heat-acclimatization and modification procedure with at least 5 tiers, escalating from the mildest level needing precautions up to the level at which activity is cancelled — covering equipment modification, work-to-rest ratios, water breaks and shaded rest.
The statute fixes exactly one WBGT threshold, and it is about supplies rather than activity: ice must be provided to every student-athlete and every coach any time WBGT is 80 °F or higher. Athletes must also have unhindered access at all times to hydration and a cooling space — shaded or air-conditioned.
The statute says nothing about how WBGT is measured — no device requirement, no rule about apps or websites. That silence is not permission: your district's policy may impose one, and it controls.
Districts must also establish a process for reporting and investigating any case where a student-athlete suffers a severe heat-related illness requiring emergency treatment or resulting in death.
This page has no threshold table on purpose. Virginia's numbers live in local school board policy, and inventing a statewide table — or copying another state's — would be the exact failure this site exists to avoid.
